Newcomer here. This is my first attempt. I just won an eBay auction for my starting point, and won't get the bike for another 10 days or so. But I thought I should identify the obvious areas to address first.
The bike is an OX Platinum Kelly Deluxe Single Speed. Comfort is my #1 priority, and I've been assured that Chris Kelly made a very compliant, very comfortable ride. I believe the frame weight is ~ 4.5 lbs.Current build list from the eBay listing:
Kelly Deluxe single speed. Size large. True Temper OX Platinum steel.
Salsa Cycles CroMoto rigid fork.
Shimano Deore LX crank. Generic (Shimano, most likely) bottom bracket.
44 tooth Blackspire chain ring, generic 16 tooth cog, both new.
Aluminum BMX VP platform pedals.
Shimano XTR V-brakes and levers with new Kool Stop pads, generic cables and housings
Chris King NoThreadSet headset
Bontrager RaceLight 620 bars with new generic ergo grips
Ritchey WCS seat post
Specialized Fizik Tundra saddle with carbon rails
Specialized front hub, unknown model, 32-hole.
Shimano XT rear hub, 32-hole, with aluminum spacer (It was a nine-speed cassette).
Mavic X517 SUP rims
Serfas Drifter tires 26x2
With my limited knowledge the obvious first steps will be to replace the tires and the fork. A Trigon carbon fork at 520g instead of the 1130g CroMoto. And 440g Compass 26x1.75 tires instead of the 850g Serfas tires. Just those items will drop it 1430g, or 3.15 lbs.
Are there any other 'easy' steps that will take the weight down in large chunks? Can I get it under 19 lbs?
Thanks for any assistance.
