Hi,

Could anyone tell me if the saddle height should be changed when one goes
from SPD-R to SPD-SL?

TIA, Derk

Probably.

....but not too much...

I'm not sure about the saddle height vs those 2 pedals. I do know
that the saddle height changes depending on which shoes you wear. My
Specialized Mtn. Comp have a nice,thick cushiony insole. My Shimano
T091s have thinner insole. When I change shoes I need to change
saddle height.

How can you be that exact about saddle height? I'm not beinmg sarcy, I'm
genuinely curious.

I'll answer that since I've been known to be an anal-retentive [censored] about
this stuff.

I tend to notice things like seat height 'cause it makes my knees feel
different. Too thick a sock/shoe sole and I feel it. Some times it means I sit
on the saddle in a different place too.

I've noticed that since I'm not riding 2-3 hours every day right now (back
problems) that I don't notice the smaller changes as much. Gross changes I
still feel. Just not the smaller ones.

HTH,

M

I don't know about anyone else, but my knees make me extremely fussy about
saddle height. My seat needs to be pretty much exactly 785 mm above the
center of the bottom bracket with my present bikes and shoes. If I drop the
seat height to or below 780 mm I get aches in the front of my knees at the
top and/or bottom of my knee cap, while if I raise it to or above 790 mm I
get really nasty pains in the tendons behind my knees. At 785 mm I am
happy spending all day in the saddle.

This is with 170 mm cranks and the Dura-ace version of the SPD-SL pedals,
actually. The Ultegra version of the same pedals made me push the seat
3 or 4 mm higher, if I remember correctly. I once spent a month with
175 mm cranks on a bike, based on a bike shop recommendation that a lot
of good climbers (not me) my size tended to prefer them, and found there
was no saddle height at which I could get comfortable. At my prefered
seat height I got pains both front and back of my knees simultaneously.

When I take a bike for a test ride I can tell within about 30 seconds
that it has cranks which are longer than 170 mm. Beyond tire levers
the only tools I feel a need to carry on my regular rides are a small
tape measure and an Allen wrench for the seat clamp, in case the seat
post slips a bit. I am just fine riding bikes with a variety of geometries,
and find things like handle bar height and cockpit length to be
non-critical, but I seem to really, really need the saddle height and
crank length to be right to be comfortable.
