If you haven’t done so already, it’s likely that the component parts of your drivetrain – the bottom bracket, crankset, hubs, cassette, shifters, chain and derailleurs – are some of the things you’re likely to replace or upgrade before most others.
If you are thinking of upgrading your current drivetrain or its parts, the range of choice out there can sometimes feel a bit overwhelming - should you replace like-with-like? Would it be worth upgrading to a higher spec part? What's the difference between part (a) and part (b)?
We’ve put together the various levels on offer from SRAM, along with their intended use and features…
An entry-level model in SRAM’s drivetrain selection, X5 is by no means one to ignore. It’s inspired by the company’s more race-ready offerings, and delivers smooth and precise shifting to take your off-road riding to the next level. It’s pretty common to find SRAM X5 parts specced entirely or mixed with other parts on many new hardtails and full-suspension bikes.
Things get more serious on X7, with trickle-down technology featuring heavily from higher up in the range. A Type 2 rear derailleur boasts SRAM’s Roller Bearing Clutch and Cage Lock, all complemented by X-Glide shifting – all this translates to a new level of control, precision and reliability whether you’re shredding your local trails or smashing the singletrack on a big mountain adventure.
A more lightweight, stiff and reliable option, X9 is the choice of many when upgrading to something that’ll tick both the performance and price boxes. Clean and crisp shifting is the epitome of X9, which is built to last and will look after you on thigh-busting climbs, technical descents and all day missions in the hills.
At the higher-end of SRAM’s drivetrain collection, X0 offers dependable performance and maintains accurate smooth shifting for hundreds of trouble-free miles. A smattering of carbon, CNC machined aluminium and other weight saving features makes X0 the choice of performance riders. For the more gravity-oriented out there, an ‘X0 DH’, downhill-specific option is available here too – bombproof, lightweight and durable – ready for gnarly rides in the rough.
A recent addition to the SRAM family, X01 adopts the 1x11 gearing setup (single front chainring, no front mech and a large 11-speed cassette at the rear), and promises a similar level of flawless chain management, light weight and precise shifting as the more expensive XX1 group. Because of its versatility and durability, it’s perfect for all riding styles. Read more about SRAM X01 here.
One for the weight-conscious cross-country riders, XX is a feature-filled, highly adjustable group which comes with a top end price tag. Shift performance via the company’s X-Glide technology is flawless, with a mix of carbon fibre and CNC-machined lightweight aluminium combining to produce some of the most crisp and dependable gearing you’ve experienced.
Using a 1x11 gearing setup (single front chainring, no front mech and a large 11-speed cassette at the rear) XX1 is the top end of the company’s drivetrain collection. Simpler, lighter and more durable than anything before, XX1 is driven by a cutting-edge, single-ring carbon crank and delivers fast, precise shifting for 100% performance when the going gets rough.
SRAM XX1 uses an X-Horizon rear mech with Type 2 technology alongside a super wide range cassette. It’s a race-proven piece of kit too – Swiss rider Nino Schurter has recently secured his second XC Elite Men’s World Championship title on board his XX1-equipped Scott Scale.
