OK. So I've been getting really frustrated with a riding problem I've
been having with my 29er. I tend to ride it pretty crooked. I'll be
cruising along down the road, and in order to keep it straight, my
body's twisted WAY to the right with my left arm pointing ahead and my
right arm pointing behind. This is really starting to p*ss me off. I
don't have this problem with my 24" Torker but it's prevalant w/ my
homebuilt 29er. The uni is straight. I put it on a super flat welding
table we've got at work and used precision gage blocks under the forks
and there is no twist at all to the frame. The wheel is nice and true
and I've got a friend who's ridden it and he said it feels just fine to
him. Oh yeah, the seat is on as straight as I can possible get it by
eyeball.
I've read in other posts that the Schwalb Big Apple seems to be
sensitive to little things like the road crown but I've tried riding on
both sides of the road and this doesn't seem to help. Yesterday, I
decided to mess around with tire pressure.
I weigh 180 lbs. and I tried the following pressures. I would start in
my garage and use a hand pump with a built in pressure gage and then
ride around a couple of blocks always going the same route and on the
same side of the road just for consistency.
25 psi (lowest my gage would read); Tire was very soft and mushy. Just
plain old difficult to steer. Decided I just couldn't ride here. Soft
enough that I think I'd pinch flat if I dropped off a curb.
30 psi; Couldn't tell any difference from 25 psi.
35 psi; More controllable but still felt like I'm riding 'crooked.'
40 psi; Slight improvement over 35 psi.
45 and 50 psi; These pressures felt the best to me. I still felt like
I'm riding a bit crooked but it was the least pronounced at this
pressure.
55 and 60 psi; I'd say that these pressures were the worst. I
couldn't tell a difference between the two and my crooked riding was
the most pronounced.
I still beleive that I've got some riding technique 'issues' going on
but I also think that this tire is fairly sensitive to pressure. Too
low and it's just mushy. Too high and I think that I end up with too
much of a point contact at the road and the round tire profile wants to
kind of roll off to the side a bit. I dunno, it's just a
theory🙄
Anybody got any suggestions or comments? Something I might have
overlooked? Should I maybe try a Nanoraptor or just keep riding 'til I
figure out how to overcome this whole crooked thing?
It kinda sucks 'cause I'd love to ride my 29er more but I keep
gravitating to my 24 because I ride it so much better.
