Shimano 105 5800 11sp Groupset
Shimano 105 5800 11 Speed Groupset The Shimano 105 groupset continues to evolve. This Shimano 105 5800 11-Speed Groupset has successfully narrowed the gap between 105 and Ultegra. Whilst both groupsets undeniably benefit from the joys of trickle down technology of the elder statesman Dura-Ace, the performance of Shimano's 105 11-speed groupset is precise, efficient, and reliable. Crisp, Light, and Stiff Every facet of Shimano's 105 groupset has been updated from earlier models to deliver an accurate, crisp, and stiff performance. Lower weight, and now featuring an 11-speed drivetrain, this Shimano 105 groupset opens the door of pro-level technology to part-time racing enthusiasts and recreational cyclists who enjoy clean, crisp, and accurate shifting each time they change gear. Featuring excellent durability, this groupset will keep you shifting for thousands of miles. 5800 Crankset: The new 5800 Crankset features a new four-arm Hollowtech II design similar to that of the current Ultegra and Dura-Ace. The new chainset is stiffer and lighter than the five-arm design it replaces and Shimano have reinforced construction around the chainring area to further improve the stiffness-to-weight ratio.105 FC-5800 Chainset 53.39t or 50.34t Crank Arm Length: 172.5mm HOLLOWTECH II design: optimum balance of lightweight and stiffness New gear dimension for great improvements Improved gear for less chain touch in small/small combination Hyperdrive SG-X-chainrings DUAL-SIS-compatible Includes Press Fit Bottom Bracket Dual Control Shifters Set STI 105 ST-5800: Shimano 105 now gains the light and responsive shift action found in Dura-Ace and Ultegra Levers, with a new compact shape that's been borrowed from the levers of Shimano's more expensive groupsets.

My latest Cycling Groupsets
Shimano are a Japanese manufacturer primarily known for their cycling components, and to a lesser extent shoes and clothing. Founded in 1921, Shimano is widely believed to be the largest cycling component manufacturer in the world, having reached this status through a combination of innovation, reliability and value for money. Whatever your style of riding, whether it be road or MTB, Shimano will have a component range to suit your level and budget, from the low end Alivio and Tiagra to the professional standard XTR and Dura-Ace. Over the years, Shimano have revolutionised bicycle gear, brake and pedal systems, such as the recessed SPD, Hollowtech crank arms and smooth shifting Hyperglide sprockets. Initially their component range faced competition from Suntour, whereas nowadays their primary rivals for market share are SRAM and Campagnolo.
