Some disappointment this morning after another test ride around the garage (it's been a week of rain).
I noticed the first time I rode it that the bars had a tendency to wander, especially to the right. Handling was a bit nervous and required constant input to the bars.
I put this down to a few possible causes- tyre choice, pressure, incompatible tyre on rim, headset bearings.
After making sure both tyres were at 80 psi I rode it again and noted little change.
This morning I swapped in a known set of wheels (Araya 700c) with good tyres (Maxxis Refuse 700 x 23 @ 100 psi) that I knew were fine on other bikes.
Results were the same.
It was then that I noticed that despite the wheel pointing straight ahead there was a twist in the forks, slightly to the left. This explains the tendency to countersteer to the right so with little invested ($100) for the bike plus parts I can use elsewhere I may have to cut my losses.
It may be a case of using the Deore driveline on another bike and converting my "throwback" bike with it's relaxed geometry into a light touring rig- the long wheelbase would be a good fit.
The front fork limits me to a 25mm tyre but that's ok, with a 28mm on the back it's comfortable and has eyelets on the rear dropouts for a rack.
The 13-28 7 speed on the back should be a good match for the Deore triple and the upright riding position is already comfortable.
