One: find the mounting points
A conventional rear rack uses four: two eyelets at the rear dropouts and two on the seatstays.
Look before you buy. Two minutes there saves a return.
Two: the lower mounts first
Bolt the rack’s legs to the dropout eyelets loosely. Everything else is adjusted against these, so leave them slack until the end.
Three: the upper stays
The stays are usually adjustable in length. Set them so the platform sits level — not nose-up, which throws the load backwards, and not nose-down.
If the seatstay eyelets are missing, P-clips around the stays do the job. Put something between the clip and the paint.
Four: heel clearance
The check people skip. Sit on the bike, or turn the cranks by hand with a pannier fitted, and watch where your heel passes the bag.
Racks with several mounting positions let you move the platform back; some do not. This is worth checking before you tighten anything.
Five: tighten in order
Uppers first, then the dropout bolts, working toward even tension. Use the figures your frame publishes for the eyelets if it publishes any — they are small bolts in aluminum and they strip easily.
Thread-locking compound on rack bolts is worth it. They vibrate loose.
Six: check the load limit
Published by the rack maker. Frame-mounted racks carry far more than seatpost-mounted ones, and the figure matters if you carry a laptop and a lock every day.
After the first loaded ride
Re-check every bolt. Racks settle.
The questions riders ask
What if my frame has no eyelets?
P-clips around the seatstays work for the upper mounts and are a long-standing solution. If the dropout eyelets are missing too, a seatpost-mounted rack is the remaining option, with a much lower published load limit.
Will a rack fit around disc brakes?
Racks intended for disc bikes have a different stay shape or supplied spacers, because the caliper sits where a stay wants to go. Check that the rack states disc compatibility before ordering.
