Gone Fishin'

HEY!

I'm not actively blogging here anymore. But if you got here because you were searching for something about bikes, you might want to check out my latest project, Vermont Goldsprints. In summer of 2014, I bought a used goldsprints racing setup and have made it a mission to get more bikes in more people's faces by putting on fun races in unexpected places. Come join me!

Dan's Stimulus package CVT Road Bike II: The Ground-Up Build

Dan commented on my last stimulus bike project post that he'd be interested in exploring the "scratch" or "ground-up" build of a CVT road bike some more. So, I'm going to take a stab at it here.  He also mentioned that he could do without the rack, fenders and chain guard, so that opens up a little budget money for some other things.  In an attempt to see what we might be able to do, I headed over to the super-secret discount bike parts store and put together a shopping cart. I started with the frame, and for each part, I sorted for the cheapest compatible part and went with that.  here's what I came up with:

That covers all of the parts except for the CVT Hub, spokes for the front and rear wheel, and maybe some headset spacers and grease. I can't belive the cheapest 700c rims on Nashbar were Velocity Deep V's. but so goes it and they would look pretty sweet in this application anyway.   So, What's our total:

Nashbar Bits:    773.72 (I'm guessing 40 bucks on the shipping)
Nuvinci CVT:      350.00  
Spokes:                42.25 (for both wheels, I checked what I paid when I built my most recent set)
Hubub Adapter    70.00 (shipped, again an estimate)
Chain tensioner   40.00 (shipped- we might be able to get away without this, but I'm reservinf judgement for a bit there)

Total:                 1275.97

More than the Cadillac we started with, but we're now talking about a CVT road bike with hand-built Velkocity Deep-V wheels and pretty nice parts. (a carbon fork, even!)


Some ways we could save some bucks on this would be to source parts a little more carefully, perhaps mixing in some eBay purchases and things from some other retailers. We could also hit Nashbar on one of their (very few) "20% off everything" sales, which would save us about 140 bucks.

Oops- There's one more thing:  we may have to use a cross or touring frame.  Conflicting web research suggests that the NuVinci needs 135mm dropout spacing.  Many cross frames come that way, and Surly also does a bunch of frames with patented "gnot right" spacing of 132.5mm, allowing the use of 130mm road hubs or 135 mm mountain hubs.  Just a nagging detail to sort out. Nashbar does the same 132.5 spacing, and a touring frame and fork combo is 199- which would save us a few bucks.  A cross frame and fork combo right now would add a few bucks to the build.
