Trek Rail upgrades, what have you done?

[hongeorge]

I agree that it doesn't sound right unless that's an aftermarket fork of some sort and then with some kind of an adapter headset for the bottom. All Rails have the 1.5 bottom and 1&1/8 top head tubes which is pretty much the industry standard for bikes at this level and category.

Newer Gen 4 carbon rails have a 1.8 lower, mine has the same

@bfletch2006 - if your existing fork is a zeb, you could leave the crown/steerer in place, and swap the internals and lowers of the new zeb ultimate onto it. And you can rebuild the leftovers into a 1.5 steerer fork which will be easier to sell on.

Yeah, we haven't seen or gotten any 2024 carbon Rails, but I see in the spec sheet what you're saying. It says "1.8" oversize tapered steerer". I must admit ignorance of this new to me standard for a bottom steerer size of 1.8" vs 1.5"...wasn't aware of it. Oh boy...another "standard" to deal with. I see it appears to be an emtb specific issue...I think. Oh well...time marches on...LOL!

The EMTB hubs aren't that much different, I think swapping the freehub is probably all you need to do - only difference is the EMTB hub engages all 6 pawls at once (54 points), whereas the regular bub has them offset, so it's 3 engaged at a time (104pts). Easier/cheaper than a whole new hub and build

The wheels are built with Chris King hubs. They are centerlock and the Rail doesn't play well with with centerlock.

@hongeorge -that is a great idea.

I've been running Hope Pro 4, J spoke style on my HT Roscoe 8 for almost 4 years now. They have been 100% flawless. I do like the 108 engagement on my Shimano Rail 7 hub. I might do the Hope Pro 5 or some I9 Hydra's next time around.

The 2022 gen 3 Rail 9.8 were first to have the 1.8" lower headtube diameter. I use the FSA baseplate reducer to run a Fox 38.
I have never been a fan of trek and specialized proprietary suspension designs. C-dale even more so.

Another "standard", bummer.
