I'm thinking there might be something allowing contaminants to enter your hose system, possibly through the pistons.

quick question dudes;. I just picked up a like new Hightower V2 frame and when i went to put my fork on and tighten the steerer tube to preload bearings i noticed that i could barely get the top cap tightened before the fork begins to seize up and bind or something. This is my first experience with integrated headsets so im not sure if i even installed the fork correctly. Coming from a YT Jeffsy that had a Chris King ZS44 headset. The crown race that's on my fork is the Chris King one, could that cause the issue? Heres some pics

You need the crown race for the integrated headset that’s in the frame. They are specific for every headset (or at least manufacturer).

You'll need the Cane Creek crown race.

Possibly part of the problem, but Shimano also refuses to hard ano their master pistons so metal will slowly wear into the fluid regardless. This problem is worse on their lower end brakes especially with hard riding.

Lower bearing looks crooked, and yes, you need proper crown race,they are not a universal standard as many seem to assume. It always cracks me up when someone sells a used frame or fork with a partial headset.

That is some nasty brake fluid it reminds me of a used marzocchi fork I bought back in the day. Don’t think the oil was ever changed in them.

It's an integrated headset, so the bearing can't be crooked unless the bearing seat in the frame is out of spec. It's probably just not fully seated in the picture.

Highly possible shimano pistons are prone to micro cracks in the ceramic

Guys please help.
I over-tighten rear axle on Fuel EX 2020 and I cant unscrew rear wheel, any advice?
Today I put wd40 on the end of the axle and I will wait until tomorrow to try again...
Do you know any other method?

Thanks in advance.

If you can't get it out, or the head strips, you'll have to cut through the hub end cap and cut through the axle.

If the threaded side has a spot for the allen wrench try that side first, sometimes its a bigger hex head with more engagement than the usual spot, can make it easier, plus if that side strips you still have the other side

If you can get good engagement on it with a Allen wrench, try using a 1/4 inch impact driver, sometimes it's the shock of the impact that will save the day. Worst case it strips and you are back to cutting. Hope it doesn't get there for you.

I may have stripped my bottom bracket on my Trek Scratch 9 (2011). It has the Fox DHX RC-4, I want to look for a new frame, how do I get started with compatibility?
