Thanks for the input!The critical thing will be your chain line. The 170 hub width combined with your 164 BB axle width should do it. Not familiar with the rear tire, so I don't have much to compare with, but if it's less than 4.5" or so wide, you should be able to make it work.
The short cage rear der will handle your reasonably tight 11-25 cog spacing, and make for snappier shifting.
** Edit** I just saw the 20 x 4 Vee Apache that should work fine for a good chain line.
And, WOW is that CooL!
You might want to consider a larger chain ring, like maybe a 42 t, to get the benefit of that gear range. Otherwise it is going to be geared pretty low. And remember, you can always stand up and crank for short steep climbs.
Speaking of cranks, I would also consider a longer crank arm length. 140 is fine for single speed 'kids leg length', but if you want to ride this beautiful build, I would go longer.
Otherwise TJ, you definitely have my attention on this one! As always.... RaT oN~!
Thanks for looking out for me. Yup, not only heavier but it will be a little taller too.That big heavy wheel will be a lot to spin. You may want an easier gear than your Fastback, as the same ratio will be more work. The Worksman trike I roll at work is a ton, but its lower gearing really works for accelerating.
Edit: oops, I was thinking about another bike, forgot you are using 10x. You'll have plenty of gears!
I'm putting these tubes under a *big* squeeze. Believe it or not I did fill them with sand before bending! I'll be able to use some of the flattening and dimpling to me advantage for the chainstays... another *big* squeeze. I thought the first pass bends had just a little too much and wanted to try to tweak them a bit. I plan to use the same set-up for the seatstays / cantilever tubes. Those will be half inch. Hopefully between the die tweaks and smaller diameter tube there will be less flattening on those.
Never tried salt only sand. I have a small funnel that I use to fill the tubes. I've also switched from welding plugs into the ends to using duct tape for all bends. The heavy duty tape seems to work as well and is a lot faster.Sand is commonly used when bending freestyle with no mandrel. I use salt because it's easier to manipulate (pretty easy to pour down the tube from the container) and it's cheap.
Where are the curved mandrels supplied with that bender,
and why aren't you using them?
Totally honored to even be mentioned in connection to this. That looks like a killer selection. 10 speed is a great way to go. Not as expensive as 11 and better selection than 9.
