The problem is finding a Trek dealer who has one in and lives within an hours drive. Trek won't allow dealers to post bikes, they have to be set up and ready to ride (apparently) otherwise they lose their licence.
The Trek website is pants, I rang up all the "dealers" in Suffolk and Cambridgeshire and none of them were Trek dealers any more or failing that they only carried a limited range and wouldn't get a bike in for me.
There is one just south of Cambridge but they can't get any until the end of October whereas Chevin seem to have them in stock. I'm not driving 3 to 4 hours each way for a £450 bike though.
Pants… I'll have to wait.
I'm quite prepared for the forks to be pants but they'll see me through the winter and then I can get some carbons, maybe putting the bouncy ones back on for the winter. I have got some old XTR cranks, loads of light stems, various sizes and shape of bars and seatposts and pedals just sitting in a box so I can upgrade it without costing me too much. When I get nicer wheels for my Swift I can swap them over and I may end up with a nice light bike. I just have to get my hands on one first though.
