Started experiencing frequent slipping from my drivetrain - the chain is about due to be replaced and the cassette with it as they just now measure 0.75 on my chain checker. However, that shouldn't be worn enough to slip like this in every single gear, and the N/W teeth seem too tall to have the chain be skipping there.

Could it be the star ratchet rings in my 240s hub? Have had the hub for 5 years now, they look like they're in OK condition but maybe the wear isn't super visible on those small wedge teeth.
It definitely could be, are you running the 54t ratchets?

Rockshox Recon TK silver solo air FS-RCNS-TK-A2 not sure of exact year,
question: can I use a newer compression damper cartridge in an older fork?
my damper has a broken lip at the bottom that holds the seal in place, and I can't find an exact replacement,

Probably. The inner stanchion diameter is very unlikely to have changed. As long as the new damper is the same length, same diameter, and has the same threading on the top cap you will be fine.

Watch out for the top cap threading though. Thats the most likely thing to have changed. If it has changed you can probably combine parts from the newer and older damper to cobble something together. It's hard to be any more specific without more info though.


You can work out what year the fork is by looking at the code on the back of the csu. The first number after the T is the year of manufacture.

thanks for the reply, so T3 would be 2013 then? is there any type of color code on the dampers?
just guessing, blue 30mm, yellow 32mm steel, black 32mm alloy, and threading would follow that? with 32 steel having a larger ID than 32 alloy due to wall thickness? or did they use the same thread on steel and alloy?
my old damper is yellow plastic with 43-4015-016-010 on it, steel 32mm tubes for 29" wheel
and I found for sale at several on line dealers a 2011 damper 11.4015.306.000 just not sure that it will fit
I am also guessing the 26" damper is shorter than a 29" damper?
this is an old fork I just want to make work for a beater bike, so I dont care if going from a 2013 to a 2011 damper is a bit of a downgrade, from the pics it appears the only change is the lockout lever went from being held on with a snap ring to a screw

had this happen on a cheap nukeproof rear hub, thought it was the chain also went to stand up to pedal one day and stripped 75 percent of the teeth off the ring gear

Wear would be very visible on the Star Ratchet.

18t. I took it apart again, I think I can see very slight wear on the edges of the ring teeth.

a-aha,

Contact Stans. There's a chance it's an off-the-shelf part, but I'm not optimistic.

I was changing my brake pads then when I was tightening up the pin the top piece broke off on one of the sides. I over torgued it I guess, It still got threaded on one side. Will this be okay when braking or should I get a new caliper asap?

new caliper

Likely, but there's a chance it's functional if it's just a pad retention tab. Photos would be helpful.
