ULTEGRA R8100 – Join the Pursuit of Next Level Speed
Where Science Meets Real-World Performance The new Shimano ULTEGRA R8100 series builds on the DURA-ACE design philosophy, delivering pro-level innovation with real-world accessibility. Now featuring a 12-speed drivetrain and refined Di2 wireless shifting, ULTEGRA embodies the pursuit of next level speed.
DURA-ACE Shared DNA Engineered with the same performance-focused DNA as the flagship R9200 series, ULTEGRA offers uncompromising speed, control, and reliability—helping competitive riders push their limits further than ever.
Shimano’s Fastest Shifting Yet The ULTEGRA Di2 platform incorporates advanced electronics with improved processing efficiency between motor, gears, and drivetrain.

get this or the mint and lime one and you won't be disappointed. chews are far better than gels. has the texture of like Turkish delight (not spicy tho). disposing of gels is stillcky tube in your pocket (if you litter then you're doing wrong), this one is just a wrapper and a little bit of cardboard back in your pocket no problem for later.
