The front fork is something I found on Alibaba, I needed a very long steerer and this one was the only one I could find. Next time I will make one, I got a fork fixture recently
Today I brazed the front triangle, I did it in two passes
Do I need a longer BB? Using 113 right now, it seemed short to me but Microshift calls for it and I just followed along, I wonder if I should swap it out for a 118.
Clearance is around 3mm
Brazed cable guides and got it all quickly together and got out around the neighborhood.
The goods:
It didn’t break on me, no weird noises, rides good.
The bads:
The crankset is too close to the chainstays for comfort, I will have to notch the chainstays, just to be safe.
The rear triangle is perfectly centered, however, the wheel is not dished symmetrically, I could re-align the wheel or possibly move the rear triangle to the right a bit, that would also give me a better chainline so I am trying to strategize on what is the best approach.
I am not sure how a minivelo is supposed to feel, it rides good, the frontend is very quick, I assume it’s the 20in with “smooth” tires combo
Not sure if I missed it but what tubing did you use for the steerer and headtube? I’ve been thinking about building something like this as a cargo bike for a while now.
It shift wonderfully, it’s the smoothest gear change of all the bikes I own.
I was worried about the chainline as well but so far it’s not been a problem, given I have only ridden ~10 miles on it, the weather in Norcal is awful right now.
I am planning another build for my wife and I will use a boost hub to get the back out a little more, however, keep in mind that with a 20in wheel, smaller cogs gets more use than the big ones, I can push a 11-40 without issues while I would not be able to do that with my 29+ bike, not in the same way anyway.
and this does look like a lot of fun.
