Technology transfer at Sram

While individual mountain bikers keep fitting road components, individual road cyclists are now bolting mountain bike components to their bikes: at this year's Giro d'Italia, there were some real road bike hybrids on show.

For the steep Dolomite climbs at this year's Giro, David Millar's Cervélo S3 bike was equipped with an XX cassette with an 11-36 gear ratio in combination with an XX rear derailleur. The remaining shifting components came from Sram's Road-Top Red groupset.

Due to the identical gear ratios on the shifter and receiver on the road bike and the bike, this mix of components works perfectly with Sram. With Shimano, the combination of STI brake/shift levers with mountain bike components does not work without exception, based on the mix of 10-speed MTB crankset/derailleur and STI.
