My trek runs wtb laserdisc with unmarked hubs my free hubs nasty. I've regreased it and 're shimmed it however the bearing surfaces are nasty so if I can replace the free hub the rims will go for a bit longer.
I think it might be a sram body

Any ideas people

Looks like a joy tech one. Very much like Spesh , trek and cannondale use on there oe wheels
Best bet is a trip to a dealer with body in hand
They can have some very slight differences
If it's the original, take it to a Trek dealer,along with your frame number, and they should be able to identify the exact model using Trek's tech site (not sure if it's a public site).
I bought the bike 2nd hand and its a bitsa, it might be an original but I am not sure
I have a Bontrager Race Disk wheel and a Kooka rear hub. Both take a freehub that looks remarkably similar to yours. I got the last one from a Trek dealer. Swinnertons in Stoke.
