Shimano: components for road, gravel and mountain bikes

Shimano was founded in Japan and built its history in bicycle engineering. Today it produces drivetrains, braking systems, pedals, footwear and e-bike systems. Its ranges include Dura-Ace, Ultegra and 105 for road, GRX for gravel and XTR, Deore XT, SLX and Deore for mountain biking. Di2 identifies the electronic shifting technology found in several families.

The Shimano catalogue at Evolution Bikes includes 1334 products. You can search for both components to upgrade your bike and spare parts for maintenance: from cassettes and chains to shifters and derailleurs, through to rotors and disc brake spare parts. Check availability in each item's product details.

How to choose a compatible Shimano component

Start with the code on the component fitted to the bike and the intended use. The family name helps you find your way, but compatibility also depends on the groupset generation, number of speeds and mounting standards.

  • Cassettes: check the number of speeds, wheel's freehub body and rear derailleur capacity. The Ultegra CS-R8000 cassette is an option to consider for compatible 11-speed road drivetrains. Choose the tooth counts with your routes and climbs in mind too.
  • Chains: choose according to the drivetrain and the model's compatibility guidance. Available products include the Shimano CN-M8100 chain. Before fitting, also check the length and connecting system.
  • Pedals: the SPD PD-M520 are suitable for shoes with the SPD attachment system, commonly used in MTB and gravel. The Ultegra PD-R8000 SPD-SL require shoes and cleats from the SPD-SL system, designed for road cycling.
  • Brakes: for rotors and pads, check the calliper model, rotor mounting, permitted diameter and compatible braking material. When replacing a system, also check the levers, hoses and fittings.

Evolution Bikes is a family-run shop near Caserta, established in 1974 and now in its third generation. A workshop, bike fitting and e-bike support complement sales, with shipping throughout Europe. To choose a Shimano spare part, ask us for advice in store or via chat, keeping the code of the component to be replaced to hand.
