Component manufacturer SRAM have just announced details of some upgrades to their existing product line. XO, X9 and X7 have all been upgraded to XX internals, zero loss shifting and all in a smaller package. The top two lines get ball bearings for the mechanism in the pull lever and the XO shifter now features carbon fibre to save weight.
All in all it adds up to an upgrade to the existing line more towards their premium XX offering and hints at the kind of changes we should expect to see in the future such as 1x systems. Pricing is €236 for the XO, €111 for X9 and a bargain €63 for X7. They should be in stores already.
Also improved is the X7 rear mech which now brings the Type 2 technology to this price point. A roller bearing clutch keeps chain tension high but allows for disengagement to remove the rear wheel easily. It is 10 speed and capable of handling a 36 tooth cassette. Weighing in at 293 grams it is avialable in three cage lengths too – short, medium and long.
These systems are fantastic, virtually eliminating the need for chain devices. It operates on a needle bearing too so it is really smooth and promises great shifting at an amazing price point of just €80! Expect to see it on shelves in May.
