help with a new build to save my aching back
At physical therapist and doctor's recommendation, I need to seek a bike with a smoother
ride than provided by my '07 Jamis Aurora with 32mm tires. With these tires (max I can fit), I need to ride w
high pressure to avoid pinch flats due to my considerable bulk (235#). Because of MY body
geometry, short legs for my 6'3'' height, frames with horizontal top tube also do not provide enough
seat tube extension to use a thudbuster. In principle, I can "unweight" when I encounter
poor pavement. I do this when I can, but my commute takes me through Somerville and
Cambridge Mass. I would need to fly to unweight enough on some of these roads.
I've tenatively identified the Salsa Fargo as a candidate because it meets five criteria:
1) allows wide tires for better ride on poor Massachusetts roads
2) frame geometry allows use, when needed of a thudbuster
3) appropriate for my two weeks of unsupported touring each summer
4) disc brakes to provide better control (specially while touring or wet weather)
on steep downhills
5) I must have drops. In the drops is my most comfortable position.
I'd like to buy a frameset and move most of my components over. I have some compatability
1) I have a set of handbuilt wheels with disc hubs for the Jamis. The Jamis rear spacing is 130,
while the Fargo is 135. Can I change out the rear wheel axle and use spacers for the new
bike? I realize the wheel would be stronger if I have it re-dished, but I might start just by
adding 2.5mm on each side.
2) The Jamis and Salsa both use a 68mm bottom bracket. The length is not specified for the
Fargo. Is that length actually determined by the crank, so I should be able to transfer the
BB/crank/chainrings from the Jamis to the Fargo?
3) My Jamis uses Shimano Tiagra dual control STI, and I also have interruptor brake levers.
Yes- I use my "safety levers" often when negotiating heavy traffic. I would like to use these
brake levers with Avid bb7 road brakes. Are they compatable? I don't expect to have the
great brake feel that a mountain biker demands, but I do need to be able to hold to a slow speed
and stop on very steep grades. With my weight, this is an issue with the cantis on the Jamis.
I love my Jamis, and I spend more time on my bike than in a car. However, I can feel the
aggravation of my disk from the harsh ride. I tried bigger tires, and it helped a lot. Unfortunately,
I couldn't quite fit them and they eventually ended up rubbing the frame. So I need to look
for other options.
I (and my aching back) thank you in advance for any help.
