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. The result: Shimano’s fastest, most precise shifting system ever, with enhanced wireless security and ultra-low power consumption thanks to a proprietary chipset.
Smoother Drivetrain Performance Two new 12-speed HYPERGLIDE+ cassettes (11-30T and 11-34T) feature ramped profiles for seamless, shock-free gear changes—whether upshifting or downshifting—keeping you smooth and efficient under acceleration.

Extended inner plate improves chain engagement and retention
Absolutely my go-to shop for everything triathlon. From gels to bike service, Graham really knows his stuff and gives honest, practical advice rather than just trying to sell the most expensive option. Service is consistently excellent and I would highly recommend paying him a visit.
These are great, much better than gels. They have the consistency of something like Turkish Delight. I find them a lot easier to eat while riding than the sticky gooey ooze of gels. The mint and lemon flavours are also good.
