What rims do you have now?

I have had good luck running Stans Flow EX3. They have been pretty bomb proof for me and the few rock strikes I have had haven't done much damage. I am also not hard on wheels though so others may have a different opinion.

Just had my bearings replaced on my dtswiss 350 rear hub by my lbs went home put the freehub back on everything spins ok soon as it's fitted back in the frame under tension it won't freewheel and keep the cranks spinning ??? Undo the axle and it spins fine any ideas

There should be a spacer that goes into the freehub. If it’s missing, you’ll have the problem your describing.

If they used the wrong lube (too thick), it can cause problems.

Could it be too much grease behind the star ratchets, meaning they can’t disengage properly?

It's not tried that as well it's like it's been compressed to much

Probably one of the bearings not fully pressed home. If there is a gap between the bearings and the center spacer that lives between them, the bearings will get stiff when preloaded by the axle when you tighten it up. It's easy enough to accidentally leave a bearing .5mm away from being fully pressed home, and it's kinda hard to tell theres any problem until the wheels back in the bike.

Id take it back to the shop and they'll probably just tap the bearings home and send you on your way. If you are confident doing it and you need your bike running soon, this isn't too hard a jobe to do at home.

Hey guys, First time posting here. Just cracked the damper body on my vivid coil shock. Does anybody have any suggestions on what I could do? https://imgur.com/a/PHCLnno
Hello again, So I think I am going to have this piece CNC'd Does anybody know where I could find the files for this kind of stuff?

That sounds like a massive pain, unless you already have the equipment and want a project. I would just save the headache and buy a new shock. Shop used if budget is a concern.

Ya, I don't think you're going to be able to track down files for that.

I have never CNC'd stuff before, Is there a way to somehow scan the broken piece?

There might be a way to scan but most people measure the parts by hand to try and replicate it 3D cad like solid works. It would probably cheaper to either buy a replacement part or shock than spend the time machining a new part.

Well a new shock costs about 300 euros for me, How much does CNC'ing cost?
