I appreciate all the comments, but here's the thing. I'm old, OLD...69 years, and the weight of the bike matters a lot to me because I will be carrying it a lot. I currently have a 20" BF and it's around 26 pounds with seat/pedals and I can't carry it more than a small flight of stairs. My son lives up 3 flights with no elevator and I ride to visit and then we go riding. And, no, I don't want to ask him to carry the bike up the stairs for me, that's just the way I feel. So, I configured the bike with a titanium seat post, elite fork, velocity rims, and other weight saving items. The SS is partly for weight but also I ride my BF in pretty much one gear - I hardly ever shift so the gears are pointless. Finally, I've a Shareroller friction drive coming eventually which will provide motorized climbing gears for the rare times I need them (just when I want to bike to Tilden Park).
I get you all think the price is crazy but it meets my needs perfectly (but any weight savings is good), I'll be able to take in stores on all my errands (been very car-lite for 5 years) so I don't have to lug a heavy u lock anymore, etc. etc. So - don't judge me =).
I upgraded the cranks on my current BF (bought used and restored by me) from these same cranks to FSA Sora's with a hollowtech BB and the difference was remarkable in smoothness. So I'm already familiar with the stock crank and I know I would appreciate a nicer one. the stock one is 750 grams, I'd like to go lighter but definitely not heavier.
Any reasonable replacements would be appreciated.
Thanks,
Granny on a SS
