A catalogue that sells everything to everyone is not a shop. These pages state, for each part, which standards it needs from your bike — and say "unknown" when we cannot check them.
Parts
Parts
- Bottom brackets
Bottom brackets by shell standard and the crank spindle they provide.
- Brake calipers
Calipers and levers by mount standard and actuation — every brake dimension is safety-critical.
- Brake pads
Brake pads by caliper family — the shape is the fit, and the caliper on the bike decides it.
- Cassettes
Cassettes by speed count and freehub body, each with the largest-cog limit it asks of the rear derailleur.
- Chain guides
Chain guides by ISCG tab standard.
- Chains
Bicycle chains by speed standard — the one fact that decides whether a chain runs on your cassette.
- Cranksets & chainrings
Cranksets by spindle standard, and chainrings by bolt circle or direct mount.
- Rear derailleurs
Rear derailleurs by speed count and actuation, with the largest cog each one reaches.
- Handlebars
Handlebars by stem-clamp diameter (and the tape that goes on them).
- Headsets
Headsets by upper and lower cup standard (S.H.I.S.).
- Pedals
Pedals by spindle thread — 9/16" on adult cranks, 1/2" on one-piece and many kids' cranks.
- Brake rotors
Disc rotors by diameter and interface. Diameter is a safety-critical fit: the fork and frame state a maximum.
- Seat clamps
Seat collars by the outside diameter of the seat tube.
- Seatposts
Rigid and dropper seatposts by diameter and shape.
- Stems
Stems by handlebar clamp and steerer clamp — two safety-critical diameters.
- Inner tubes
Inner tubes by wheel size.
- Tyres
Tyres by ISO bead seat and width, checked against the frame clearance on file.
- Workshop & accessories
Lube, tools, bottle cages and the other universal parts that fit any bicycle.
