My new TT bike has the regular Dura Ace 9000 shifters on it, but they're not ideal in terms of UCI regulations, as I'm not able to get the proper reach with the measurement going to the end of the shifter in a horizontal position.

I've previously used SRAM R2C shifters on my old TT bike, but I want to be able to use the 11 speed derailleurs. As far as I can see, nobody is making R2C shifters for Shimano 11 speed - correct? Are there any shifters that are shorter than the DA 9000 that will work with DA 9000 dereailleurs?

My other options are to go either electronic(will cost quite a bit), or swap the drivetrain to SRAM Red and then use the R2C shifters for 11 speed.

Tinea Pedis knows this set of rules better than I do so hopefully he chimes in but are you able to use the 80cm reach exemption without the need for proof of Morphological exemption? Could eliminate the need for equipment changes.

• For pursuit events (individual pursuit, team pursuit): the position is identical to that
for road time trials with the saddle withdrawn at least 5 cm behind a vertical plane
passing through the centre of the bottom bracket and an advanced position for
handlebar extensions of a maximum of 75 cm in front of the centre of the bottom
bracket. An exemption for morphological reasons is possible for riders of small
stature who want to bring the tip of the saddle forward up to the vertical plane
passing through the centre of the bottom bracket. Furthermore, an exemption for
morphological reasons is possible for riders of large stature who want to advance
the handlebar extension to up to 80 cm in front of the centre of the bottom
bracket. Only one exemption for morphological reasons is allowed per rider.

Yes, the 80 cm rule is in full effect for me. The trouble is that the shift lever is about 4-5 cm long, which means that I have to decrease the real reach to 75-76 cms as the total reach is 80 including the levers. So shorter levers could be the solution.
