Just bought a rather tasty looking Hemlock frame off ebay (pic below). Planning on swapping as much over from my Dialled Alpine as possible as I can't really afford it - so it'll have to make do with 140mm Pikes for now. Also going to have to get a bigger seatpost, but will find the cheapest possible for now and upgrade to a dropper in a couple of months.
Can you tell me what sort of front mech will work? I have an XT one with the low clamp, but all pictures I've seen have the high clamp. Will the low clamp foul on the pivot? Would a high clamp or a direct mount be best?
Will I get away with a short cage rear mech? Not sure if the movement of the chain stay will cause problems. The short cage is just on the limit of it's range on my hard tail, and I wasn't sure if fs bikes need a bit more throw to account for the suspension.
Finally, what's the best headset to get, bearing in mind I will be using standard 1-1/8th Pikes for now but will try to upgrade to tapered or 1.5" Lyrics in the summer. Is there one which uses the same cups in the frame and just swaps adapters for different forks? Something with low/zero stack height would be good as my steerer is not very long. Want to avoid unnecessary removal/installation of headset.
