ORBO Klunk That! (based on a true story)

[us56456712]

Temporary fit up of new crank. The 24T chainring was the only one that fit without filing around locating pin hole. I will need to add a spacer to get everything to tighten up.

Plenty of clearance, Clarence.

How are you going to get the tire to fit? I wonder if you could extend the drop length enough by lap welding drops from a kids bike on top of the existing drops?

Robbed this Brooks B-66 from another bike.

Will need a 5/8" to 7/8" shim. Ordered on on 2/10, still not here. Looks like I'll have to steal one from another bike.

I’ve had problems with those double rails slipping on klunkers. It doesn’t seem there up to that level of abuse. You can weld up a simple seat sandwich to make it bomb proof.

Sorry, my pictures are misleading. I had the wheel slid all the way forward in the dropouts temporarily. Tire clearance shouldn't be a problem after I get my drivetrain sorted out and the chain tensioned.

That’s good news

I had briefly looked into doing this on another bike that I was trying to use a micro adjust seat post.

I borrowed a shim from another bike, got my seat mounted.
