Shimano 105 chainsets are known the world over for their reliability and performance. Having been refined from the previous version the 105 R7100 furthers this reputation. For this edition, Shimano have carefully engineered the R7100 crankset to offer an excellent balance between stiffness, strength, weight, as well as rotational performance. The result is a chainset equally suited to big days riding in the mountains, as it is fast bunch rides. Trickledown Performance Thanks to the benefit of trickle-down technology, the difference in quality between a 105 chainset and the more premium Dura-Ace or Ultegra versions is closer than ever. Now, with the addition of Di2 to the 105 R7150, the decision to purchase anything more expensive is even less justifiable. That is, of course, unless you simply want to spend the money on the flashiest tech around! All The Tech As with any product from the Japanese component giants, the FC-R7100 chainset employs some of the company’s top tech. Shimano’s famed Hollowglide technology means the outer chainring is hollow, to reduce weight but is engineered to do so without diminishing strength. This is the same technology employed on a number of the brand’s cranksets, including the top-tier models: Dura-Ace and Ultegra. Additionally, Hollowtech II technology is used to keep weight to a minimum, while maintaining strength and stiffness. The result is a crankset that won’t leave you bogged down on a climb and ensures maximum power transfer from your legs to forward motion. Again, this is the same technology employed in Shimano’s top-of-the-range models. Whether it’s the perfect chainset for big days out on the saddle or something for racing your local criterium the 105 R7100 is the perfect option, particularly for those slooking at a more affordable price range. It offers smooth shifting, an excellent balance between weight and stiffness, and won’t break the bank. Product Features: The Hollowglide structure reduces weight but maintains strength Crank Arm Lengths: 160, 165, 170, 172.5 and 175mm Gear Combination: 50-34T Q-factor: 148mm Weight: 765.6g (50T, 172.5)
Enjoy quicker, more precise front shifting and efficient power transfer thanks to its HOLLOWGLIDE structure. It cuts weights yet maintains stiffness, strength and performance. What’s more, the crank arm length starts at 160mm so smaller riders can benefit from SHIMANO’s legendary shifting.An attractive aluminum crank with hollow arms for lightweight, rigidity, and durabilityThe newly designed crank arms offer an optimized balance between lightweight and efficiency. The crank, formed with hollow aluminum technology, is anodized with a beautiful gloss black anodized finish, giving it a luxurious look. The resin ribs on the back of the chainrings are SHIMANO 105's unique structural design that achieves both thorough weight reduction and crisp shifting performance.Key Features:Optimal balance of stiffness, strength, weight and rotational performance,HOLLOWGLIDE structure cuts weight yet maintains strength for better power transfer and quicker, more precise front shifting,Crank arm length: 160, 165, 170, 172.5, 175 mm Gear combination: 50-34T, 52-36T Q-factor: 148 mm.

Many top features are packed into the Centaur crankset. The four-arm design allows for independent bolt circles, offering greater stiffness and structural integrity, and also provides additional versatility, as a single crankset is compatible with both standard compact and semi-compact chainrings. Add these features to the first aluminium crankset with an ULTRA-TORQUE axle and the result is a component that is very similar to the top-of-the range part.Key Features: Four arm design,Two chainring combinations: 52/36 and 50/34,One single crank for both chainring combinations,Optimized inner surface on both cranks,Ultra-torque™ axle,Chainring inner design optimized per each combination,Three crank lengths available: 170, 172,5 and 175 mm,Campagnolo ultra-torque bb cups required .
It's also very versatile, as if you want to change from a 50/34t to a 53/36t or vice-versa, there's no need to change the entire crankset as the spider is compatible with either chainring combination. Smooth Performance The Centaur's chainrings have a special anti-friction coating to encourage smooth chain operation. The chainrings also feature Campagnolo's "MPS™" technology, which enables quick and accurate shifts no matter how hard your pushing and in all weather conditions. Also, thanks to the use of the "Ultra Torque™" bottom bracket system, you'll enjoy consistent, rigid performance and optimised power transfer. Technologies: MPS™ (Micro Precision Shifting System): Optimised design of the up-shift and down-shift zones and of the profile of the teeth – enables fast and precise shifting in all types of conditions. 8 chain upshifting areas and 2 chain downshifting areas result in faster and more precise shifting, even under stress. Ultra Torque System™: Six years after its introduction, this system is still considered the best performing crankset spindle in terms of stiffness, low weight and efficiency of power transmission. Campagnolo found a way to permanently conjoin the semi-axles of the bottom bracket to the respective crankset arms. This redesign made it possible to considerably reduce the lateral dimensions at the axle level and prevent annoying contact with the ankles when turning the pedals. Furthermore, despite the narrow side profile, Campagnolo has been able to position the bearings outside the bottom bracket shell, resulting in greater axle rigidity from the increased axle diameter.
Campagnolo Centaur Ultra Torque 2x11 Speed ChainsetThe Campagnolo Centaur Ultra Torque chainset brings top-end features and technologies to the masses. Featuring the same four-arm spider as seen on Campagnolo's "Super Record" model, the Centaur has the extra strength where it's most needed, ensuring excellent rigidity for efficient gear shifts, sprinting, and climbing.

Named after a brutal 4 mile, 1800ft climb called Alba Road in Santa Cruz, California, the Praxis Works Alba X crankset is designed to laugh in the face of such climbs, with an excellent range of gearing options & lightweight construction all without a heavy weight price.Lightweight solid forged arms are incredibly stiff for efficient power transferM30 spindle is compatible with BSA, BB86, 386EVO, BB30, PF30, T47, BBRight & OSBB bottom bracket shells BB's sold separately10/11spd LevaTime II chainrings are cold forged for supreme shift quality & durabilityVersatile modular design can accept 2x or 1x DM chainringsLightweight at just 800g (170mm w/ 50/34T Chainrings)Where most cranksets can only be fitted with a small selection of chainrings, the Alba X is designed with versatility in mind. While equipped with 2x chainrings as standard, the direct mount design can easily be swapped out for a 1x chainring or another 2x combination in a different ratio. Praxis wants you to have control. Add in to this compatibility with pretty much any bottom bracket shell on the market when used with the appropriate bottom bracket, and you have an incredibly versatile crankset that is happy to grace lightweight carbon race bikes or tough steel gravel bikes. The crankarms themselves are solid forged, which gives them immense strength and stiffness, so you can be sure every watt of power your legs can muster isn't wasn't with flex. Despite this, the crankset is extremely light at just 800g. The M30 spindle also helps to keep weight low and stiffness high.Whereas most chainrings are stamped or machined pieces of aluminium, the Alba X's chainrings are cold forged from 7075 T6 aluminium and then hard anodized. This unique method creates chainrings that are just as light, but are much, much harder wearing and provide slicker shifting for longer. Further improving the shifting performance is Praxis Works LevaTime II Shifting Technology. LevaTime II Shifting boasts a series of synchronised ramps and strategically placed shift pins to help deliver perfecting every time. Lightweight, stiff, smooth shifting and extremely versatile, the Praxis Works Alba X crankset is perfect for riders who want maximum performance without breaking the bank.
