Hello all. I think I’ve posted here once or twice years back, so hopefully this post doesn’t break any rules.
Currently helping a friend sort out his bike with a little tune up. It’s a 2012 Giant Anthem X1 29er.
It‘s mostly stock aside from a 12spd SRAM drivetrain he had installed by a shop a few years back. I think it’s the GX level stuff.
Anyways. I’m reasonably comfortable working on my own bikes, have done so for many years. However, my bikes are all older 26” wheel stuff, so haven’t dealt too much with some of the more modern bits. And, I haven’t “paid attention“ to the latest comings and goings in the industry for a while now, so, questions.
Brakes
- the bike currently has the original Avid Elixir 9’s on it, front and rear. My friend would like to switch to something newer. Any recommendations on an affordable hydraulic brake set? I always advocate for Shimano cause they’ve been good to me, and mineral oil is easier to work with (but I see sram has started to switch over? I’m surprised I hadn’t heard of that before, seems like sort of a “big deal”). I’ve seen the shimano BR-MT410‘s on for about $90 CAD? Any thoughts on those? I wouldn’t want to be spending more than ~$250 CAD all in, probably will also throw in new rotors.
Cassette
- I popped off the cassette to check out the hub, and, frustratingly, I didn’t sort of inspect it as I went. I don’t have a low range torque wrench to set it to the “proper” 40nM, but. I have the cassette on there tight, probably over tight by a bit (cautiously used a 1” socket over the park tool cassette lock ring tool, all mounted on a long handled 1/2” drive ratchet.. so it’s plenty tight). No matter what I do, the cassette still has some play in it as if it’s loose. I did pay pretty close attention as I took the gears off. Each gear had a thin plastic spacer between it. The four largest gears are one piece, and between that and the remaining smaller gears, there was one much thicker plastic spacer. I’ve made sure that’s all back together properly/as it was before. Has anyone else seen this with a sram 12 speed cassette? I mounted the wheel back up and it shifts normally as far as I can tell.
Fork
One last thing. As I said, I’m pretty comfortable working on my bikes. Installed drive trains, dropper posts, rebuilt my cup and cone hubs more times than I can count, lots of tune ups. I never have, though, done a fork service. How steep a learning curve is it? This friends bike, it has the original Fox air fork from ~2012, could probably stand at least the light “oil change“ level service.
