SO I swapped out an old set of TRP Spyres on my 2015 Giant TCX for a new set of Sram Force Hydro discs.
I'm super happy to have them on, they feel great at the lever, but I admit I haven't gotten to ride them yet.
One thing that keeps throwing me off though is that the front caliper spacing (in particular) looks...... weird. It just looks somehow too far out to me, and I noticed that when I look at down through the caliper from above there is quite a bit of space between the top of the disc and the top of the 'cavity' within the caliper.....moreso than I'm used to seeing on other brakes. It almost looks like the pads are only contacting 1/2 of the braking surface of the 160 disc.
I looked at the spacers my mechanic used, a 17.5mm and a 12.5mm, and see that this is the appropriate setup for a CPS Caliper and a 160mm disc on 140mm post mounts. ...it appears that IF my calipers were 'standard' calipers I would only need a 12.5 and a 7.5mm spacer. I just don't know how to tell whether my caliper is CPS or standard to tell whether the mechanic may have made a mistake or not. I looked at the picture on the sram caliper installation .pdf, but the differences between the two caliper types seem too minute for my eyes.
Anyone know how I can check my caliper type and ensure that my spacer arrangement is correct?
