Well i've been on the TRP Spyre's for a while now... SOOOO insanely happy.

Dont both with Hy/Rd - the Spyre's are cheaper! and dont require all sorts of bodge/additional expense to get them working

I originally wanted the Spyre's but they were not available at the time, and the HY/RD's were on special. If I had known about the issues before I bought them, I would have just waited for the Spyre's to come back into stock. My own fault for not researching enough!

Anyway, now that I have fitted the short pull arms, they are working like they should. So unless they have some other fault that shows up, everything seems to be in order.

I am only on my first set pads, so waiting to see how the self adjusting pads work out. If everything goes pear shaped, I can always swap over to the Spyres later. The short arm conversion was $USD40, so it's not a huge loss if things don't work out.

bled them twice & got all the spongyness out of them, now they're also not requiring any shims too - feel great & lots of bite at the top of the range.

Either way - SUCH a pain to have to do this, it would've been a 5min job (if that) to adjust mechanical spyre's.
so i'm putting an order in for some spyre's for the front & i'll do a comparison


Quite like my HyRd's available at a time when full road Hydro' was very limited availability - was a bit put off by dual nature - seemed illogical but does work and no faffy cable pull issues using 105 and Ultrega.....anyway just looked at front to check wear and notice a piston is stuck :-( - had a stuck one on rear last time changed pads so maybe its common - bike is well used so a bit of a surprise...as to pad wear not really been a problem for me - I run cx/interupters and just use the adjusteron these to tighten the cable - only time been near to bleeding is left bike upside down on back seat of a car overnight and turned upright had a horrible whistling noise - TRP confirmed they will vent if left upside down......replaced some BB7's which had to adjust that impossible to turn dial weekly think still got scars on knuckles Given an option now would go full hydro as it has crept down but if on a budget with a good set of cable levers already in hand I'd buy another set

I immediately had the same issues as everyone else with the lever pull, and through further research found that the HY/RD is specifically designed around the cable pull of SLR-EV Shimano Levers, which pull a lot more cable.

If you have older Shimano levers (before DA7900/Ultegra 6700, you’ll have issues, but they are really only designed for 11-sp systems, and Tiagra 4700 (which is SLR-EV).

Anyway, I have just fitted a pair of aftermarket short pull actuator arms, and I now have magnificent braking with the levers coming about half way to the bars under full braking.

Much better than the hacksaw fix I have seen suggested, or the shims behind the pads.

So, if you have SRAM or older shimano levers, or Campag, the replacement arms are perfect.

I ordered direct from the guy who sells them on Amazon (above). Apparently they sell out rather quickly every time he makes more of them.


Timely response! just pulled the trigger on some HYRDs so ill be sure to also grab the short pull arms!

cheers!

After a couple of months of commuting, both wet and dry, im a big fan!

I didnt buy the short arm conversion though (yet?)

Majority of my riding, and therefore braking is from the hoods, and i find i dont mind the travel at all.

If i pull from the drops, with the added flex of the lever i could see how that would be unsettling, but seeing as i brake from the hoods it dosnt both me at all.

Have had a few unsuspected lockups with what i thought wasnt much pressure from my fingers!

Happy days.

Mine are going great. Ironically my first commute to work after being off injured was in the pouring rain. Happy to report that the TRP HY/RD provide excellent braking without any squealing like the Avid brakes & Rotors.

I have not had to adjust the pads at all as yet, and lever feel has stayed the same. So far so good.

This close to pulling the trigger on some HY/RD calipers to replace my Spyre's (sacrilege, I know, based on this discussion!) The front Spyre pad adjuster bolt is frozen in, and the 3mm hex is now rounded out. I guess that's what you get for not undoing them every three months...pretty naff. I will shelve them (literally, not metaphorically) and keep an eye out for replacement adjusters to rebuild them at some stage. I need a little more clearance between spokes and caliper body too, the arm on the Spyre brushes the new front wheel under load and can't be moved across any further.

I'm convinced enough. Also I can't afford a full hydro replacement for this bike.

Do you use them? I have seen them but they look like they have a very tiny oil reservoir? They also look wider than the HY/RD which may not solve my spoke issue. Will do some reading.

Had them for about a year or so. I've got about an 8mm clearance between the caliper body and spoke.
Best with a compressionless housing.
