have bought for my girlfriend a Trek Session 88 FR from 2009.
It is a very nice and well equipped bike.
The only thing I donīt like about the bike is the Totem fork and would like to change it to a Boxxer.
The bike has a Cane Creek E2 headset with a 1.5 crownrace and for the Boxxer I need a 1 1/8 crown race.
Does anybody have an idea which one I need for the change.
Have no Trek Dealers in the neighbourhood and would like to order the part online.

Cheers Leslie
