They're different bikes. They'll ride differently. Don't compromise the
handling of the Sam to try to make the two bikes handle similarly.

[RBW] Trail (I know, I know) and handlebar width

2010-02-08 Thread Earl Grey
Bear with me for a moment:

All else being equal, should a bike with more trail have wider bars to
harmonize with the handling of a bike with less trail? (In terms of
switching back and forth between two bikes.)


Here is my situation:

I have been riding my newish Hillborne and am loving it, and recently
rode my 1990 Fisher Sphinx monstercross again, whose handling used
to seem perfectly fine. After getting used to the Sam, the Sphinx
feels like it's running on bushings rather than headset bearings,
requiring a surprising amount of effort for even minor directional
changes. The headset was overhauled 2 years ago, and I do not think
there is anything wrong here. I think it's just an example of the
range of handling characteristics that one can get used to and that
work fine.

But switching back and forth sure feels strange. I don't know the
geometries of the Fisher, but guess that it's fairly standard 1990 mtn
bike geometry. I assume the issue is a high amount of trail on the
Sphinx (correct me if you think I am wrong). Here is a photo (fork
offset seems low, but I haven't measured it):

In terms of relevant parts, the Sam is sporting 42mm knobbies, the
Sphinx 33.3mm Jack Browns. The Sam has 46cm noodles, the Sphinx 42cm
Bontragers.


Here is the question: :)

I have a 44cm noodle that I am about to put on the Sphinx, but am
wondering if it would be better to move the 46 noodle from the Sam to
the Sphinx and use the 44 noodle on the Sam, to partially compensate
for their different handling characteristics?

Thanks,

Gernot
