TRP Spyre Post Mount Disc Brake Caliper


The TRP Spyre is a dual sided mechanical brake where both pads actuate providing even and precise clamping force. This translates into even pad wear and, with the addition of a simple cable barrel adjuster, the pads can be adjusted easily and hassle free. All of this in an incredibly thin 40mm wide, 154g slender package that works with any of the mechanical drop bar brake levers on the market. Sold as singles - one required for each lever.

Please note: Post mount fitting and rotor sold separately (not included)



  • Dual sided actuation for even pad wear
  • Simple adjustment and set up
  • Works with ALL cable actuated road levers.
  • Includes ultra-grippy TRP semi-metallic pads
  • Manufacturer recommends use with 160mm rotor
Mr Sato Cambie el freno de disco Tektro. Mira que son de los mas simples,y en relacion al peso no cambio nada ,ya recorri mas de 100Km con el TRP y no encuentro una gran diferencia,solo el aspecto mejoro, valio la pena pagar ese precio?
GARY Super fast delivery & communication from Merlin as usual, brakes are fantastic, easy to set up with easy adjustment. Easily as good as the hydraulic set up I had, no difference in stopping power. Buy with confidence !!
Headwesty I bought this to replace a seized, leaking TRP Hy/RD and so far I can't tell the difference. Progressive and just as much stopping power at less than half the price.
K Great brakes. Be careful with setting them up, but get it right and they are going work really well. Merlin’s service as good as ever.
Sophie Broad Second one I bought, great brake.
Sophie B Look great and really easy to set up. Found them equivalent to to the avid bb7 in terms of stopping power and have the clearance for a centre lock brake disc.
Paul Roman The disc brake calipers on my gravel bike were of very poor quality so I decided to change them for these TRP Spyres, which has made a big differnce. I am very pleased with their performance and they were relatively easy to fit, although adjusting them is not so easy.
Mr Paulywog Pretty nice upgrade over cheaper brake calipers. Happy with the purchase. Much quieter as well, no squealing.
Dr D My 2nd time to buy TRP Spyre, still think this is the best cable disc brake. On my first ride I was able to avoid a collision wtih an unattentive motorist crossing my way thanks to its brake power - already returned its money.
Freddie Omg! So much better modulation and adjustment than the old bb7 Road!
Dr Mitchell Easy to fit & adjust. Pretty good braking response.
Michail I did not want to buy hydraulic brakes for my Gravel bike. I wanted the mechanical brakes. Who has the same considerations as me, has the only choice - the TRP Spyre brakes. In my opinion - the best mechanical brakes on the market. Highly recommended.
Mr Heuer For many years I only bought expensive hydraulic disc brakes, but they often had trouble with clearance and they were difficult to adjust without having an expensive bicycle dealer doing it. Then I tried TRP and I was sold! Now I have them on 3 of my bikes and will probably not go back on the hydraulics again :-) Merlin cycles have the cheapest TRP I've been able to find, and the service is super. Good info on mail along the way and fast delivery.
Mann Previously had Avid BB5 calipers which just would not allow the brake pads to be set up parallel to the disc rotor. Decided to try these out and they worked like a charm. Easy set-up and no more disc rubbing. Should have switched sooner. Fast dispatch time and excellent packaging as usual from Merlin Cycles.
Sam Easy to install and adjust, great stopping power compared to Avid BB5.
Henry Easy to install and adjust and excellent braking performance. A great upgrade to my existing (Tektro Lyra) mechanical braking system.
Jordan I bought these to replace my TRP HY/RD hybrid hydraulic disc brakes, and the Spyre performs better than them in all respects. Having the dual action along with large 160 rotors makes for a smooth and confident stop. The barrel adjuster makes life easy when you want to fine tune stopping power. While I run Shimano on all my bikes, I prefer these calipers to theirs.
Ian The Mystery surrounding fitting and adjusting Disc Brakes is finally over ! These brakes are very easy to mount and get set up and adjustments can be made simply to keep things running smoothly. Performance wise these are just as good as hydraulic brakes and can be field maintained .
Mr barton Easy to install, just remember to buy new cables as well.
Ade Great value - probably the best low-cost mechanical calliper. Easy to fit and adjust and importantly both pads move for even wear
MattM So far so good. TRP recommend the use of compressionless cables and having swapped out my old cables this certainly seems to help matters with these brakes. I used Jagwire cables, which seem to work well. Can`t really comment on how these fair long term, but have my fingers crossed.
david Great! I have hydraulic brakes on my other bike and these are almost as good. Easy to set up and once bedded in work really effectively. They also have better clearance than my hydraulic brakes and are therefore well suited to adventure / gravel type bikes as they cope with mud/muck better. Better than expected and well worth the outlay!
Mr Jordan Product better than I had expected and fast delivery :)
Jay Perry Replaced some old Avid calipers with these and they're amazing. Modulation and feel is so much better, and they're so much easier to adjust. No more squeaking and rubbing. They came with pads pre-installed and were already adjusted to good default clearances, so installation was just a matter of bolting them on and then fine tuning for a few minutes. A great, affordable upgrade for a mechanical system.
Dr Mitchell Good quality product that is easy to fit and adjust.
Mr Slattery Easy to fit and adjust. Big improvement in braking power and modulation over one sided mechanical calipers. Price and service from Merlin excellent
Mr Corridon Early days, but more positive braking than single-sided cable disc caliper. Also quite light.
Mr Skubala Considering how much problems I've had setting up with other disc brake calipers recently (Shimano RS805 and TRP hy/rd) these were ridiculously easy to set up in comparison. Easy to centre, easy to set the cable tension right so it bites at the mid stroke of a lever pull, and most importantly, no disc rub!! Obviously the modulation is not as good as the previous two mentioned calipers, but they're hydraulic or part hydraulic. But they'll still stop you, you just have to pull the lever a tiny bit harder. If you end up with cable stretch, its easy to adjust this and there's instructions provided to tell you how to do this. I'd say this is an ideal for a commuting bikes. Fuss free and cheapish option.
Ernesto Best purchase ever: very easy set up, rock solid, firm braking and very good modulation
Stewsie Bought this as a replacement for TRP HY/RD Caliper. Yes I know this is one level down but I had already replaced the rear Caliper with one of these bought from Merlin and when the front one failed a few months later I bought another. Very easy to setup and adjust and I find the brakes powerful enough for off road use. I had already recommended these to a friend even when the HY/RD were working. Excellent price from Merlin and excellent delivery service
Mr Spearman-Oxx A definite improvement in braking over the Shimano calipers which came with my bike originally. Pads feel softer and action much more precise. Fine with cables supplied with Ultegra 8000 groupset fitted at same time.
Bobbins Chosen to replace original front cable operated single moving/fixed pad on 2011 Croix Der f to these dual moving pad. These avoid the expense / faff of hydraulics, keep it simple and give a better feel overall action. Use shall be the same 20-25 mile all season comute as on another bike previously fitted with the same 2 years ago and that caliper has been fine.
Mr Vedel Bought to replace the other TRP Spyre calipers that were stolen off of my bike, because my lock prevented them from taking the whole bike. They were out of stock in almost all other places I found or cost twice as much, but I wanted these, because I find them to be the best mechanical disc brake calipers there are.
