Shimano 105
Shimano 105 borrows technology from Ultegra 6500 and Dura Ace 7700 and is fully compatible with both. Features such as Hollowtech crankarms and Octalink splined bottom brackets are identical to Dura Ace and give Shimano 105 a fantastic performance to cost ratio. In pure functionality terms, Shimano 105 is equal to the higher groupsets and offers sporting performance and dependability. Shimano 105 is perfect for all round road use, ergonomical enough for epic all day rides and with the performance for the occasional race. Shimano 105 is available as a complete groupset in both triple and double configurations.
