MTB drivetrain and brake parts in Auckland
Chains, cassettes, brake pads and rotors from BRM Cycles in Westgate. Before you buy anything, check whether yours are actually worn. Below are the numbers our factory trained mechanics work to, and some of you will find out you are fine for another season.
The numbers
These are what we actually measure, so you can check yours before you spend anything.
Chain stretch
0.5%
Then it's done. Leave it longer and it starts wearing the cassette to match it.
Brake pads
1–2mm left
And they're done. Past that you are braking on metal and taking the rotor with it.
Rotor
Check the stamp
That's your minimum. Every rotor carries its own, and we go by that rather than a rule of thumb.
Cassette
The chain knows
There's no gauge for it. We judge the tooth profile, and a new chain settles it.
Not sure? Bring it in and we'll tell you straight. Workshop bookings can be made online or over the phone.
Or let us fit it.
Factory trained mechanics, OEM parts, done in house. The workshop is booked about a week and a half out at the moment, so get in early.
