While full details and photos of the new XTR drivetrain are yet to be released,  information on the new 2014 XTR brakes and wheels has been put to the press.

Things are looking impressive, with clean lines, further cooling improvements on braking systems and even a MTB first from Shimano with Carbon fibre rims!

The new XTR brake promises to take hydraulic brakes to the next level. Improvements over the previous generation include -

  • Material switch from Aluminium to Magnesium
  • Titanium hardware throughout.
  • Carbon fibre level blades
  • Finned rotor technology borrowed from the Saint downhill group to further improve heat dissipation on long descents (claimed up to 40°C)
  • Claimed weight savings of 40g per end - Shimano's lightest hydro brake to date!

Although Carbon wheel sets have been standard equipment on high-end road bikes for years, only recently has there been a demand for them in MTB. With their incredible stiffness/strength/weight to ratio they offer everything a racer wants at the top level. Featuring -

  • 28 spokes
  • Centrelock only
  • 29inch only
  • 100x15mm front, 142x12mm and 135x10mm rear configurations
  • Claimed weight of 1298-1349g per pair

Shimano bottom brackets are among the best in the biz, lasting for years. The new editions bearing the XTR name are claimed to have a weight saving of 20g and further reduce friction by 50%.

New XTR chain is a directional, hollow-pin design and wait for it - 10 speed. This might bring much disappointment to Shimano fans hoping for an 11 speed MTB offering from the other "Big S". Looks like it might have to wait another 3 years...

Although the new crankset, shifters and derailleur details are yet to be released it's pretty safe to say we are going to see electronic shifting. Well proven in the mainstream with the Dura-ace and Ultegra group, Di-2 XTR will offer mountain bikers the same instantaneous, incredibly precise shifts, even in the muddiest, most gruelling conditions.

Exciting stuff!
