SRAM Force D1 DUB Chainset - 172.5mm43-30T
  • £199.00
  • RRP £247.00
  • Saving you £19

More than just a chainset, SRAM's new Force DUB Chainset forms a crucial part of the Force eTap AXS drivetrain. Combined with the XG-1270 cassette, the Force DUB chainset forms SRAM's new X-Range gearing technology, offering smoother shifting and a wider gear range.X-Range gearing provides more range and smoother gear progression, so you're always in the right gearCarbon crank arms are lightweight and incredibly stiffDUB bottom bracket system adds durability, simplicity and broad compatibility (DUB BB sold separately)Crank arms are power up-gradable with separate chainrings/power meter (Sold separately)NB: 43-30 uses Wide fitment and is only compatible with AXS Wide front derailleursThe highlight of the new Force DUB Chainset is the X-Range chainrings. The X-Range rings work in conjunction with the X-Range XG-1270 cassette to provide a wider gear range and smoother progression between gears, meaning you'll always be in the right gear. The unique 10t start of the XG-1270 cassette means the Force DUB chainset can use smaller chainrings than normal while retaining a similar gear for top speed. The smaller chainrings also mean you'll have a lower bottom gear for punishing climbs.The chainrings also feature closer ratio spacing than traditional double or compact chainsets, so you have a smoother progression between ratios, keeping your cadence more consistent and requiring less rear shifts to compensate, further improving the smoothness of your cadence and speed. The smaller gap also means shifting is faster and crisper.The Force DUB chainset uses SRAM's carbon crank arms that are both lightweight and extremely stiff. The use of the DUB bottom bracket system improves durability, simplicity and compatibility over the older GXP and BB30 designs; no more wondering what crank/BB system will fit your bike, DUB works with most frames and bottom bracket shells on the market. The cranks use a unique, modular direct mount chainring interface that syncs perfectly with the new X-Range chainrings. The modular design further improves versatility; you can fit the DUB AXS Power Meter if you desire and if you want to switch from a double to a single 1X or Aero chainring you can do that too. Lighter, stiffer, more durable and with a better gear range than ever before, the SRAM Force DUB Chainset perfectly complements the Force eTap AXS groupset to create the ultimate, versatile road bike drivetrain.

Shimano XTR Trail M9020 Double Chainset Chainsets
  • £199.99
  • RRP £369.99
  • Saving you £46

This stunning model integrates your bottom bracket and chainset into one strong, robust and lightweight workhorse. Furthermore, it is compatible with all new XTR chainrings thanks to its integrated design which makes installation and adjusting easier than ever before. Its precision bottom bracket bearings are spaced further apart and are therefore more stable and longer lasting. What's most impressive, is its super-lightweight HollowTech II cold forged Dualumin crank arms deliver an excellent strength to weight ratio, so you can conquer every technical trail without any unnecessary weight holding you back. If your existing cranks are old or worn-out, this is an ideal choice of a replacement for getting back to fast and precise acceleration and shifting out on the trails. Please note: Bottom Bracket is not included   Technologies: HollowTech: Hollow forged crank arms. A lightweight crankset not only reduces the bike’s weight but decreases rotating mass to aid in acceleration. The challenge is to reduce the weight of the crank without reducing its strength and rigidity. Shimano's advanced forging technology has solved the problem through the HollowTech crank. Just like high quality frame tubing, a hollow crank arm can provide amazing strength and rigidity at very lightweight. HollowGlide: Hollow technology on the outer chainring. High rigidity hollow structure cuts down on weight yet maintains strength. Better power transfer and quicker and more precise front shifting.

SRAM Force1 12 Speed Chainset Chainsets
  • £199.99
  • RRP £225.00
  • Saving you £11

This race-ready 12 speed chainset features a carbon crankarm build, which means that riders will enjoy increased stiffness when climbing and an overall lower weight when accelerating on the flat. Its impressive strength to weight ratio is further enhanced thanks to its single X-SYNC aluminium chainring that provides exceptional durability and longevity as you tackle whatever the course throws at you. Coming equipped with X-SYNC technology, this model's chainring uses its wide/narrow tooth profile to deliver maximum chain control for an extra confidence boost on race day. One final highlight is its kitted out with a DUB compatible spindle interface for a simpler, stiffer, and more secure connection between your chainring, cranks and bottom bracket.  SRAM originated the 1x drivetrain, and the SRAM Force 1 crankset evolves the innovation. It's lighter, stronger and simpler—non-aero chainrings can now be installed with a single tool. For cross, time trial (TT), triathalon and crits, this is the king of 1x. - Single-ring drivetrain simplifies functionality and reduces weight - 48t variant has direct mount aero chainrings for better aerodynamics - Non-aero chainrings can be installed with a single tool, making gearing changes a breeze - SRAM X-SYNC™ wide-tooth, narrow-tooth chainring technology provides maximum chain control - DUB™ bottom bracket adds durability and simplicity - Can be upgraded to a power meter Technologies: X-SYNC: SRAM X-SYNC 1x chainrings provide the highest level of performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle-shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC rings are an integral part of the SRAM 1x drivetrain. Accept no imitation. DUB: The relationship between bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler—better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete system that equals better drivetrain performance. Bottom bracket sold separately.
