Just a story to share...
I've been riding a modern "upright" Trek for my daily commute going on two years. Before that I had a 12 speed Bianchi that has been hanging from my various garage rafters for more years than I care to remember.
I've cleaned it up, brushed the dust off it, made it commuter ready... The weather has finally broken around here, so I rode it to work yesterday.
Initial thoughts: I was very uncomfortable on this bike (Which is funny because I loved riding it for years). In my short commute of 7 miles, my hands and wrists seemed pretty fatigued. While riding, it felt much more "twitchy" (most cyclists would probably describe this as more "responsive") than my Trek tank. I'd actually say it was like I haven't ridden any bike in years (but I have been daily).
I've looked at more modern drop bar bikes, and noted that the hoods seem to be placed "higher" on many, than they were years ago. So this morning I tilted the bars back slightly (not a huge amount). This put the hoods at more of a 10 o'clock position within the drops, rather than in a 9 o'clock position. I also, slid the seat forward a bit.
Result: I felt much better today. This seemed a much more natural position for me.
I'm sure 17 year old me, would look at "pushing 40" year old me and shake his head ruefully. I'm just happy to give the bike a new life.
