Build number three

This is my latest effort

Features include home made 40 tooth rear sprocket, a BMX chain, no tensioner, and high pressure tires.

The tires are rated for 90psi, running them at 75psi.

The 40 tooth sprocket used to be on the chain ring!

Its just a cheap old mountain bike fitted with 27" wheels.

vmax as of yesterday was 35 mph

Would probably go near 40 but I fear a meltdown, seizure or explosion.

A lockup at 40 would not be pretty.

what size sprocket? i imagine the 27" wheels make a big difference

It has a very elegant look about it. I just can't see my big butt on something so refined looking.

This bike is running a 10t front and a 40t rear.

The wheels are 27.5" diameter

6000 rpm calculates to 30mph

But it feels like 50 !

That is a very clean looking bike. I've got a couple of old frames about like that. Hmmmmmm......................

I like it! I like it! I'm building one with a similar frame. Did you change out the drive sprocket or does the BMX chain fit the existing sprocket?
