TRP Flat Mount to Post Disc Brake Adaptor 140mm - 160mm rotors
  • Adaptors for fitting a post mount caliper to a flat mount frame
  • Each adapter is front or rear specific and rotor size specific



Mr McLeishThey do what they're supposed to. Usual great service from Merlin.
Mr ArmataPerfectly described product.Outstanding quality and service.Now new post mount brakes are fitted to my Cannondales Quick flat mount frame and fork.Bravo.Well done .Merlin.
Mr FitosI ordered both front and rear adaptors for 160mm rotors. The rear one worked fine, but the front one positioned the brake caliper where a 180mm rotor supposed to be. I'm only guessing that somehow it doesn't fit specificly with my GT rigid fork and it does look like the 140mm adaptor will be the one working with a 160mm rotor. I thought I'd point it out so someone else in the future could avoid a few days not riding the bike because of this specific mismatch.
Mr horneTop product at a very good price. Not fitted yet but used previously. Bolts for frame are quite short. But still worth 5 stars
Tom MDoes the job, comes with bolts. Used it to mount a SRAM Rival post mount caliper to a post mount frame.
Mr LukFits perfectly
DamienPerfect - exactly what I was looking for to fit TRP Spyre (Post mount) & 160mm discs to flat mount fork designed for 140mm discs. Comes with all fittings required.
Mr BennionDoes the job, sturdy, can't complain.
AdrianAs well as factoring in that you need this to fit a larger rotor to your bike (160mm in my case) you may also need a specific length bolt on top of this depending on your frame. however it is a great quality and value part, and the performance on the bike is flawless
Mr Scott-CollinsDoes what it says on the tin supplied with all the bolts for fitting and arrived next day.
Mr RoopsBit clunky, but does the job well, unlike shimano flat mount adapters. And for excellent price.
Mr Kocyigitgood product. did its job to mount my TRP HY/RD post mount brakes to my new bike with flat mount
Mr mckenzieInexpensive & lightweight adaptor
DavidBought to fit on a Malt frameset with Shimano Road post mount calipers & 160mm discs. Perfect fit!
Mr ClokeWorks perfectly enabling me to extend the life of the older disc calipers and shifters.
marcusA simple well made adapter bracket, light in weight and cheaper than the shimano equivalent.
Mr BaekWorks good with Shimano caliper and cheaper than Shimano mount.
WhiteAdaptor is performing flawlessly. No issues with fit or mount. Can't ask for anything more.
JimOrdered these to replace the 160's I was running as the back one meant the rotor was far too near the chainstay. Bit fiddly to fit but have done the job well and gives better clearance all round.
