Shimano

I got this adapter to allow me to use a pair of Shimano SH-IC100 indoor cycling shoes with Spin bikes at my gym that have SPD cleats on one side of their pedals. The Shimano shoes had 2 bolt and 3 bolt mountings, but were not walkable. The adapters have raised sides that keep the cleat recessed, making it easier to walk. They suit my needs very well, though I wouldn't use them for walking outdoors, because the hard plastic wouldn't provide good traction.

The standard 8.5mm screws have always worked well for me with Giro shoes. I recently bought a pair of Quoc Escapes and, when I tried to mount the cleats, the rear bolts went in fine, but the front bolts were slightly too short to engage in the threaded insert. That was unexpected, but consistent across both shoes. I do have a set of the longer 13.5mm bolts, but they would have been too long and I wasn't in the mood to try to cut them down. So, I ordered the 10mm bolts and solved the problem.

Ideally, all shoes would work with the standard bolts. But they don't, so I'm jusy happy that Shimano offers three lengths, and BTD stocks them.

I've worn Shimano shoes in the past, so I had a good idea about the size to select. The continuous elastic upper with the Boa system provides a good snug fit without my feet feeling pinched or compressed. They are great shoes for walking. I haven't used them on any long rides yet, it's winter here in Michigan, but I've been wearing them indoors on the trainer and haven't had any issues. I would say that they are NOT a big compromise from my 'gravel' specific shoes for riding.

Cassettes just aren't worth spending a ton of coin on, they shift the same, and weigh slightly less for an expensive one, why bother?

Shifts perfect, under load too, it's perfect. Whatever Shimano did with Hyperglide 2, it's incredible. Never misses, never really does anything wrong either. I always replace after 3 chains, so they get usually 15000 miles on them and even in the middle/common gears, they are still fine, but that's just my rule.

No issue. Like the 11/34 spread with my 54/40 up front, got gears on all sides that way and almost never need more.
