The best lightweight bikes can now give yಞou a great mix of low-weight 🅺and aerodynamic performance.
Gone are the days when you had to sacrifice efficiency and on-the-flat speed for an easier ride in the hills, with many lightweight bikes featuring among the 168澳洲5最新开奖结果:best road bikes. The majority of these bikes and the components with which they're fitted give you aero benefits while still often coming close to or below the 6.8kg weight limit that the UCI imposes on its s💖anctioned competitions.
After a few years of disc brake-eq🌱uipped race bikes being a little on the heavy side, it now seems the best race bikes are heading back down around the UCI weight limit mark whilst still retaining aero features and designs. The excep✃tion below is the Specialized Aethos, where aero gains have been sacrificed for out-and-out low weight. Specialized has carried over design features of the Aethos to the new Tarmac SL8 though, where you do get both.
The low overall weight of the best lightweight bikes is despite the general shift to 168澳洲5最新开奖结果:disc brakes, which still weigh more than their rim brake counterparts. Bike brands have learned how to use the properties of disc brakes, and the thru-axles with which they almost always come, to build a lighter frame that's still as stiff as one using rim brakes. There are fewer physical constraints on disc brake wheel rims, with the 168澳洲5最新开奖结果:best lightweight wheels saving even more weight.
Below, we ruဣn through our pick of the best lightweight bikes available today, followed by a short b𒀰uyer's guide on what to look for when choosing.

Rather than aiming for a bike that fitted conveniently with the UCI's rulebook, Specialized went all-in for a lightweight machine with the Aethos, resulting in a frame weighing just 585g ꦺ+/- 5g for a size 56cm, and a full build,ꦯ here with Shimano Dura-Ace, that weighs just 6.1kg.
Specialized has also majored in building a frame that's stiff in all the right places but shunned the ♓lightweight/aero idiom with round tube profiles to keep the frame's weight to a minimum, resultin☂g in what's claimed to be the lightest disc brake frameset available. It's also a pretty good-looking one.
The brand has bolted as many lightweight components as it can muster onto the S-Works model, with a set of 1,265g Roval Alpiniste CLX II wheels, a 9g 4iiii 168澳洲5最新开奖结果:power meter and titanium bolts everywhere. It has retained a threaded bottom ᩚᩚᩚᩚᩚᩚᩚᩚᩚ𒀱ᩚᩚᩚbracket though.
Geometry is the same as the Tarmac S🥂L8 (see below), resulting in a ride that's as fast downhill and through corners as it is when the road tilts upwards.

A happy conjunction has seen Cannondale update its 168澳洲5最新开奖结果:SuperSix Evo and release its premium LAB71 series bikes together at the start of 2023. The result is a fourth generation of Ca🍒nnondale's lightweight/aero machine that's, well, more lightweight and more aero.
The LAB71 SuperSix Evo hits the UCI 6.8kg limit, with a painted size 56 frame weighing 770g. Although the geometry hasn't changedꦗ - no bad thing - aero tweaks have saved 12 watts. Cannondale incorporates a battery slot ahead of the bottom bracket, allowing it to fit a skinnier seatpost, for example. Like the Aethos, the SuperSix Evo also now sports a threaded bottom bracket.
Our first ride on the SuperSix Evo 4 around Girona displayed the bike's all-around characteristics: light on the climbs, fast on the flat💯, great handling on descents, lively when you want it to be but mellow when you ride easy.
The latest version of Specialized's hugely popular Tarmac retains the fantastic efficiency and handling of the SL7 while shedding weight. It's also more aero, thanks to the one-piece cockpit on higher spec models and the 🌸'Speed Sniffer' headtube.
At the rear, Specialized has slimmed things out, using its expertise from the Aethos to reduce the seat tube's w♔idth. It says that aerodynamics are less of a priority here than at the front of the bike and that the skinnier sections add extra compliance.
With a size 56 frame weighing a claimed 685g, a full build at S-Works spec level has a claimed 6.8kg weighꩲt ready to ride, complete with pedals and bottle cages. Our short first ride suggested that the Tarmac SL8 is fast both on the flat and when climbing, with great power transfer.
Although the pric𒈔e tag is still hard to swallow, it's actually cheaper than its predecessor. There's not much depth to the range for those lookin🅠g for a cheaper build though.
Bianchi has reworked the Specialissima, with improved aerodynamics and a weight that🌠 now sits at 6.56kg for a size 55 in top RC spec.
As with the Tarmac SL8, the front end is where the aero treatment has been greatest, with a one-piece cockpit and nose cone to the head tube, while weight is saved at the rear. Bianchi claims that the Specia♚lissima will be faster than its Oltre aero bike at a relatively shallow gradient of between 4 and 🎃6 per cent.
With its weight, it's no surprise th🍌at we found the Specialissima a formidable climber. Its aerodynamics also make it feel fast on shallower climbs and o🐬n the flat, while the inertia feels lower than when riding an aero bike.
Bianchi's wheels weigh a claimed 1,380g and the bike rolls on 26mm tyres, both of which help, although the tyres don't provide the feeling of cornering confidence or the comfort of wider options. The ride feels slightly jittery and the Specialissima feels more generic than Bianchi's hღeritage would indicate.
While the latest 168澳洲5最新开奖结果:Teammachine R aero road bike grabs the headlines with its Formul🦩a One-derived tech, BMC will continue to sell the Teammachine SLR alongside it as a lighter-weight climber's bike.
Dropping the seat stays for improved comfort and a🌊e⛄rodynamics is now a bike-design must-have, but the BMC commitment to progressive bicycle design is such that it debuted this feature back in 2010 on the Teammachine.
The latest generation Teammachine SLR inherits that bike's DNA but with an integrated cockpit and the usual lighter, faster, stiffer, more compliant combination. It's more aero thanks in part to the bottle cage design, but also the ICS c♌arbon cockpit, although this only comes in two widths and six-length options, limiting adjustability.
BMC's D-shaped seatpost adds comfort - youꦜ can fit 30mm tyres if you want more. The frame design offers impressive power transfer thanks to its chunky down tube and bottom bracket, while the stack and reach are in the middle of the pack,ᩚᩚᩚᩚᩚᩚᩚᩚᩚ𒀱ᩚᩚᩚ making for a not-too-racy ride.
The Factor O2 VAM Disc can easily hold its own against the segment's best road bi⛎kes. It's seriously light, more than fast enough on the flats and descends with a level of confidence. Sure, there are faster bikes out there but unless you're riding at the highest level of the sport or testing it back-to-back against its rivals in a controlled environment, those nuances are imperceptible📖 to us mere mortals.
We said most people would probably be better served by the brand's more aero Ostro model, but if you are in the market for a stunning, lightwe𒐪ight bike that makes you feel sprightly every ride, the O2 VAM may be just the ticket.
We've completed our review of the latest generation 168澳洲5最新开奖结果:Factor O2 VAM which launched in late 2023. Factor claims that it improves on its predecessor's aerodynamics by 12 watts in its wind tunnel tes🥀ts and that it is 35 per cent stiffer than the previous generation bike.
The fifth generation of the Canyon Ultimate is available in three guises. We tested the SLX with Canyon's mid-spec carbon, but head up to the CFR frame and you can expect a weight of around 6.3kg - and it's still not as expensive as most of the bikes ♈here.
Our test bike came with Ultegra 12-speed (with a 4iiii power meter) and DT Swiss ARC 1400 Dicut db wheels but still weighed in at a featherweight 7.4kg with pedals. All specs get the same adjustable-width bar/s💯tem as used on the Canyon Aeroad, there's a D-shaped seatpost and 32mm tyre clearance. There is also a wide range of sizes available, with smaller frames coming with 650b wheels for similar handling to the larger sizes which run on 700c wheels.
We found that the Ultimate shone uphill, particularly when things got steep, with a stiff frame and weight distribution that gets you more overꦿ the pedals than some other options. With aero flourishes, it ticks along happily on the flat too, although the handling is on the edgier side.
The Cervelo R5's latest makeover has resulted in a 16 per cent reduction in frame weight to a claimed 703g. It is also perhaps the only bike to have got less stiff in its latest iteration, Visma-Lease a bike 💝riders demanding more comfort. Although pedalling efficiency hasn't decreased, the new headtube and fork design are claimed to increase compliance.
Otherwise, the R5 has the classic looks of a road bike, even as other bike makers have moved on to dropped stays, and despite the slightly retro looks, this is still a high-pe𝓡rformance bike.
The frame is electronic groupset co💜mpatible only and tyre clearance is now 34mm. Carbon wheels come from sister brand Reserve, with a claimed weight of 1,300g a set.
Replacing the Wilier 0 SLR, the new revamped Verticale SLR is an impressive lightweight all-rounder, stiff and 🥃punchy with aggressive geo🧔metry and reassuringly surefooted stability.
The Verticale SLR doesn’t quite have the all-day comfort of the Factor O2 Vam, nor is it quite as fast on the flat as the Wilier’s own Filante. It isn’t even the most lightweight bike on the ma🔯rket, with both the Tarmac SL8 and Giant TCR sitting at a similar weight point without pedals. Despite this though it still packs a punch, offering a nimble and eager acceleration, excelling particularly in both steep technical ascents where its stiffness and light weight are particularly beneficial and instilling confidence on fast twisting descents. It is an extremely enjoyable way to spend a fast afternoon.
A bike that combines modern performance with a traditional aesthetic (notwithstanding the green paint job that surprisingly grew on me), the Wilier Verticale SLR stacks up well against other lightweight bikes and blends high performance with a playfulness that you don’t often get in such s♒eriously competitive bikes.
Skinnier, lighter, faster and more aero than its predecessors, 168澳洲5🃏最新开奖结果:Trek’s new Emonda-killing Madone Gen 8 is claimed to be one of the be🍌st ultra-lightweight climbing superbikes, and the new upgrades certainly point to it being a formidable clim👍ber.
Riding the Ultegra Di2-equipped SLR 7 we found it blisteringly fast on the flats and exceptional on descents, with the IsoFlow system significantly improving the ride quality by maintaining a connection to the road without compromising comfort, a distinct improvement over earlierꦦ models. In a nod to gravel versatility, the Madone has upped the tyre cle🧔arance from 28mm in previous iterations to an impressive 33mm.
In the top-spec SLR 9, Trek has managed to hit the 7kg mark, integrating an exceptional stiffness wඣe couldn’t have dreamt of even 5 years ago. It’s a great all-rounder as a race bike, bridging the gap between the needs of some of the 🃏best of there world’s athletes and normal everyday enthusiasts.
The Addict RC Ultimate unsurprisingly sits at the top of Scott's lineup. The frameset, which has been 168澳洲5最新开奖结果:ridden by Roman Bardet and the rest of the DSM team, is built from Scott's HMX SL C🎶arbon and forms aerofoil tube shapes for improved aerodynamics. Following the aero trend, Scott has also completely hidden all cables within a Syncros Combo Creston iC cockpit.
The Ultimate spec model comes with a pick of the best road bike components and features an SRAM Red AXS groupset (including power meter), Zipp 353 NSW wheels and Syncros carbon finishing kit. If the heavy price tag of the Ultimate is off-putting, Scott offers the same frame in a range of build specs down to 🐽mechanical Shimano Ultegra 11-speed to cater for more reasonable budget𝓀s too.

Heavy wheels
A touch over the UCI weight limit of 6.8kg at 7.7kg, the Van Rysel Road Bike EDR Ultegra Disc still offers an impressively lightweight and high performance at a fraction of the cost: perfect for those who want a racy lightweight bike but aren’t bothered ab🧜out keeping to the UCI’s numbersꦐ.
Designed for endurance racing and capable of tackling all ꦇconditions, the EDR provides clearance for 30mm tyres for additional comfort across gravel but with 🐭a remarkably stiff frame for more aggressive climbing.
As with all Decathlon bikes, the EDR o🗹ffers a high spec for its low price, featuring a Shimano Ultegra R8000 mechanical groupset with a semi-compact 52/36t chainset and an 11-28 tooth cassette. It also includes the Ultegra hydraulic disc brakes for powerful precise braking, complemented by a Deda cockpit and a Fizik Antares saddle.
The Fulcrum Racing 3 DB tubeless wheels are on the heavier side but do offer both the stability and durability you would expect from an endurance racing bike aimed at tackling both roads and a bit of the r👍ough stuღff.

The integrated seatpost makes flying with the TCR difficult, but not impossible
The Giant TCR has b🥂een around for a long time now and has taken all manner of victories on the road in this time.
Earlier in the year168澳洲5最新开奖结果: Giant updated the TCR platform and as we reported at the time time, we felt it was a case of 'If it ain't broke, don't fix it'. The 10th generation TCR received integrated front cabling, as well as lowering weight and becoming more aero. Tyre clearance was also boosted as well as the frame stiffness-to-weight ratiꦿo. So think of a programme of improvements across the board rather than dramatic changes.
Giant offers a whole suite of TCR models incl👍uding a rim brake option and frameset. Specs go right the way up to the top-end Advanced SL models which come with Shimano and Sram builds, something previous bikes didn't do.
If you're looking for the best lightweight bike, here are the things that mark out a lightweight bike from alternatives among the 168澳洲5最新开奖结果:best road bikes.
What's the significance of the 6.8kg UCI weight limit?
With the UCI weight limit seemingly stuck at 6.8kg, 'lightweight' has been largely defined at that point, and brands have been able to focus their attention on improving other areas of the bike, instead of simply chasing grams in a race to the bottom (although, naturally, 168澳洲5最新开奖结果:that is still a thing).
Where aero bikes often have to make compromises on things like ride quality, fit and💫 user-friendliness in pursuit of all-out speed, lightweight road bikes have tended to become the all-rounders of road cycling, with development focused more on these important, but often undervalued characteristics.
The data tells us that aerodynamic bikes are faster on flat and rolling courses and on all but the steepest climbs. But let's be honest – the hills are still where it really counts. The important Strava segments are, generally, not boring sec𒆙tions of flat or rolling road, they’re hills, and, on the proper hills (once you dip below about 15kmh), lower weight still beats aerodynamics.
Most of the best lightweight bikes now sport disc brakes. Rim brakes have long been favoured because of the difference in weight, but the gap has narrowed considerably, to the point where disc brake-equippe♔d bikes are regularly skimming or bettering the 6.8kg limit.
Should I choose a lightweight bike over an aero bike?
The good news is that today you don't have to choose - many lightweight bikes are also aero. To keep their weight down, they may not have quite such developed aero features as the 168澳洲5最新开奖结果:best aero road bikes, but many bran🦋ds' lightweight bikes have aero ꩲtube profiles.
Couple that with aero seatposts, integrated one-piece cockpits and deep-section 168澳洲5最新开奖结果:lightweight wheels and you don't have to sacrifice watts on the flat to save wa𝕴tts on the 💖climbs.
On the other hand, there are now plenty of aero bikes that are not that far off the UCI's magic 6.8k🦩g, so you've꧃ got even more lightweight choices. A full-on aero bike will still be the more rapid option if you want to ride fast though.
Does a lower weight provide a tangible difference?
Perhaps more crucially, lightweight bikes still retain the power to impress your friends or family members, because weight is tangible. Show them an incredibly expensive aero bike and the first thing they'll do is pick ♋it up and complain that, "It▨'s quite heavy… How much did you say this cost?"
By the time you've started explaining that "over a typical 40km rolling coཧurse, performance modelling shows that this bike is 45 seconds faster at 50kph than an equivalent lightweight bike…" they'll likely have lost interest and wandered off, thinking that you got royally ripped off.
A lightwe꧂ight bike provides an obvious tangible difference, and, sometimes, that provides a greater psychological benefit t𝐆han the few intangible seconds offered by manufacturers. It's fair to say most of us will still get excited by a really light bike.
Do I need to spend a fortune on a lightweight bike?
Unsurprisingly, carbon fibre dominates the scene for lightweight road bikes. Its unique, tuna🌺ble characteristics make it the perfect material for making light and stif🐷f bikes that excel when pointed uphill. The downside is that these lightweight frames and components tend to come at an exorbitant cost.
As the great 168澳洲5最新开奖结果:Keith Bontrager once said: "Strong, light, cheap. Pick two." That said, if the UCI limit is what you're looking at, you don't necessarily need to buy the top-of-the-range model these days, which will often actually be lighter than the UCI's minimum weight limit. Some brands are even able to offer builds with Shimano Ult𓆉egra that can still hit the 6.8kg benchmark; just don't expect them to be particularly ch🔴eap.
Of course, bikes are readily discounted, so it's worth taking a look at our roundup of the 168澳洲5最新开奖结果:best road bike deals to find the best bike-to-price ratio.
