Hello all, I've searched for something about this, and haven't had any luck..
I have an old Trek 1000 that I had a LBS put a new fork on.
Before installation they told me the handling might change so much that it could fell "un-rideable" and I "might not like it" etc. because it'd lower the whole front of the bike a few MM (i forgot now, it was something between a 4-10mm difference.)
He explained that Trek forks are "special" and a bit higher than most other forks and it'd be best to use another Trek fork (I was going with a no-name cheap one < 1/5 the cost of a new trek fork).
I accepted the risk, got the work done, and the bike handles/rides excellent with the new fork (also feels very "soft".. it's carbon from 2012 replacing aluminum)
I rode it before getting the work done, but not very much or for very long..
I have a commuter bike and a race bike, this bike serves as the backup for both (it's quick and light, but still has eyelets for rack mounting)..
Every time i ride it, it feels great at the time and just after, but i wake up with incredible neck/upper back pain the next morning.. we're talking short commute rides 10mi round trips for work here.. around 20-25min on the bike each way..
could the slope of my top tube (a reverse slope or "forward" slope, down from the seat tube) really screw up my posture/body? i'm wondering if i just need to keep playing with the fit (i've already adjusted the stem length/angle and experimented), or if this bike just won't really work well because of the geometry. i specifically try to keep weight off my arms, and i'm accustomed to riding 60-100mi rides weekly and i don't own a car or ride the bus so all other transport is via bicycle.
The frame size is the same as my other (also Trek) racing bike that fits perfectly.
is this all in my head (a coincidence?)? a matter of playing more with fit? or do you think a "reverse" top tube slope is actually causing harm here?
thanks, and sorry for the lengthy post.. maybe i should've put this in the frame builders section?
