Atelier 700

Nobody walks into a bike shop asking for an 11-speed HG-splined 11–34T cassette. They point at the bit making a noise. This shop works the same way: pick a bike, pick the region, read what fits — with the two spec sheets we read to say so.

Every bike page lists its regions; every region page lists the parts that belong there with a verdict — fits, fits with an adapter, does not fit, or unknown. A bike we have not finished verifying says so at the top of its page, and only universal parts are sold for it.

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.

Why your 11-speed chain fits — and the 12-speed one does not
Chain compatibility comes down to one standard most boxes print as a speed count: the chain width. Here it is for the two KMC chains people ask about most, and what it means on an 11-speed and on a 12-speed bike from the fleet.
