Rail (625Wh) Zeb ultimate clearance with knock block removed

[scott.kibbler]

Sorry if this has been covered but searching im finding different answers.

We know a zeb ultimate hits the frame on a medium, what about a large.

Is it also material dependant? if it clears on a large is it carbon and alloy?

Thanks

Hi Scott. Maybe you’re aware of this but Trek has a specific Zeb Ultimate fork available from rock shox that fits the steering tub size/outside diameter on Trek’s only. The fork will fit but there is no “step” difference. If you know what I mean?
Since I have a medium Rail I’m not sure if the fork needs a knock block for a large size Rail. Someone here may know.

Yea i know about the trek specific version with the wider crown. I have a set on a levo sl and looking to buy a rail to transfer all my parts too. Looking to know if they clear on a large carbon or aluminium.

I have a large Rail 625 with a pair of aftermarket Zeb Ultimates and there is plenty of clearance. I still run a knock block on mine as I have no reason to remove. Buy it could easily run without on the large.

apologies for the pic quality, the bike is in the rack locked up

Thanks for that. Is yours alloy or carbon?

I can confirm that there is plenty of clearance on a carbon L.

Brilliant. Thanx everyone for your help.
