Interesting effect of wheel change
« on: May 13, 2017, 09:33:24 pm »
I've been running the M5 on a 700C/28mm rear and 26"/40mm front dynohub for a while. Swapped the front out for the original 700C/25mm this evening.

Found the forward vision less of a problem than I remember.  Definitely felt easier progress/less rolling resistance as might be expected, but I wasn't prepared for the reduced feel/response in the steering.

Interesting.

Years ago, when I used to build and race recumbents, I built a SWB that I used an original Raliegh Chopper front wheel & tyre in for the first outing, as I didn't have a brake that would work with the intended wheel.

On this set up, I could ride laps of Herne Hill velodrome, no hands!

When I put a lighter, narrower and slightly bigger wheel in, and a better headset, it got into a shimmy when I tried to ride hands off.

Maybe running a heavier dymano wheel in your bike was having a similar damping effect which gave a better feel to the steering?
If it ain't broke, fix it 'til it is...

could be, I'm also thinking the much bigger contact patch of the 40mm marathon vs the 25mm slick will have a large effect.
