TRP Spyre sticking

JesseD

On Saturday halfway through the club run my rear brake lever went a bit loose, upon closer inspection the TRP Spyre caliper had locked in the clamped position so the cable had gone loose. I managed to free it up but it seems it had clicked and stuck in the clamped position. Has anyone had this and if so how did you fix it. (apologies if my description isn’t particularly clear)

I've done this a few times, follow this guide:

Make sure you have a bowl to put all the bits in...

It's easy though, you just need to take them to bits, clean off all the shite, put a load of fresh grease in, do them up again.

Don't get a load of grease on the brake pads ;-)

awesome, that's a job for tomorrow night then!

so attempted this last night and only got so far as I realised i couldn't find my T40 torq key, still managed to get the caliper off and cleaned and working again which is a bonus, also took the opportunity to replace the pads on the front and back as well and its nice to have working brakes again!

One thing I did notice is the pad adjustment screws on the front have rounded off (done prior to me owning the bike) so the left pad on the front is rubbing slightly but not enough to notice, I am sure as the pads wear down a bit this will stop.

The stopping power now is pretty good which has got me thinking about how good hydraulic brakes must be, any recommendations for a cheap but good Hydraulic set up (must work with Shimano shifters)

Presume you mean you want to retain your mechanical cable shifters but have a hybrid style disc brake system. ie hydrailic actuation provided by mechanical cable pull.

For that you are looking at TRP Hy/Rd or possibly Juin Tech

I seem to recall that Bendertherobot did a review of the Juin Tech's on his blog - found the link

The alternative is to go full hydraulic which will mean thowing away/selling your existing mechanical shifters and buying a hydraulic set - not cheap

For proper full hydraulics on drop bars you will have to change the shifters as well. I've got a TRP Parabox convertor connected to mechanical Shimano shifters. Works a treat and has a very short cable run and is hydraulic from the stem down so no problems with sticky cables. They are no longer made unfortunately, I got a used demo unit cheap. You may be able to find one somewhere. Hope did a similar thing but I don't know if that is still available. The next step is something like the HyRd calipers which are cable all the way down to the caliper then hydraulic, so they are supposed to self adjust. Not tried them but most people seem to rate them highly.
Interrupted by work and was beaten to it.

The Hope V-Twin is still widely available although quite expensive (but cheaper than full shimano hydraulic swapover).

The Giant Conduct is another hybrid solution which looks very promising and is priced very reasonably although availability at the moment seems nonexistent - it is still in stock abroad though and used in some of the forthcoming giant models (which would imply it isn't disappearing).

I hadn't really thought that far ahead to be honest, but if the performance is very good with cable pull hydraulics such as the Juin Techs R1's then i would probably go that route instead of spending a fortune on a fully hydraulic system. The R1's look promising and for £125 (ex vat) they are cheap as well.

May wait for the Spyres to pack in completely and go for a set.

I see reading the review provided by arolwood that the discs arent recommended, anyone have any idea why and which discs would you recommend?

I like the look of that, and at £250 not earth shattering (HyRd's work out at £180).

Just my 2 penneth...I've used Juin in the past and an on Spyre's now. Juin were good, nice bite and much better lever feel than the Spyre's, but the rear caliper seized on mine in not much time and after looking about online it's seems a common problem.
