thought you would have learnt about buying tat from here mike!
from putting in Trek remedy 8, 2009 model, steerer tube 1 an 1/8th (so top of the tube is the same size as on your other bike??)
and if it is fatter at the bottom (crown) it is probably 1.5"
which gives you:
TOP) SHIS:ZS44 - 1-1/8" ZeroStack (ZS) Threadless
Bottom Headset) SHIS:ZS56/40 - 1.5" ZeroStack (ZS)
So not much use
have a look here too?
If not (i hate saying this!) but take it to a shop! only way i got mine was by taking it to Evans...could always buy hope tapered headset...
Wheels:
this looks like a good place to start?
Sorry out of time at comp, post up a pic on FB when you get a chance, and let me know what its like...want a full susser after what i saw on a mountain round here
cheers bro!
