DR ◣◢ Posted July 28, 2020 Share This sounds almost as hard as finding a replacement bolt for a seat post. Good luck. If you're in Jhb you might find something at Reliable Bolt in Edenvale. Link to comment Share on other sites More sharing options...

I've been told to try both Reliable Bolt and Robot Hardware, both are close enough to the office. Link to comment Share on other sites More sharing options...

If you're in Jhb you might find something at Reliable Bolt in Edenvale. it looks like you were right. Did a tour of the nut & bolt places, no luck. i dont think Reliable Bolt wanted to help, as soon as I showed them the pic of what I want they said they only have m6, then they sent me to Gelmar of all places.

DieselnDust Posted July 28, 2020 Share new bolt and nut didnt work, simply not enough clearance between the big cog and the spokes.I shaved it down as much as I was comfortable with, anything more and I'm not confident there is enough left of the nut to do the job. I'm going to go look for a sleeved nut today. That way I can enlarge the hole on the cage and the sleeved nut can slip in there out of the way.Did you try the bolt through the back plate First and nut on the outside?

Did you also find their lack of mask wearing to a bit shocking? Link to comment Share on other sites More sharing options...
The Ouzo Posted July 28, 2020 Share Did you try the bolt through the back plate First and nut on the outside?Still not enough clearance with the bolt I am using.But, the plate has a slight recess in it, I'm going to try and machine the diameter of the bolt head slightly smaller to fit in the recess, and maybe trim the dome slightly so its not so pronounced.This is similar to what I'm using on the outer side with the way I've trimmed the nut there is sufficient clearance to the stopped pin.

The Ouzo Posted July 28, 2020 Share Did you also find their lack of mask wearing to a bit shocking? to be honest it didnt even cross my mind, was more shocked at how quickly they determined they could not help. Link to comment Share on other sites More sharing options...
DieselnDust Posted July 28, 2020 Share Wow OK I'm really surprised there isn't clearance. There's generally more than a centimeter, around 12mm gapis your hanger not bent? Link to comment Share on other sites More sharing options...

There's generally more than a centimeter, around 12mm gapis your hanger not bent?this is a road bike with an 11 spd cassette, I think the tolerances are pretty small.(and its the upper jockey wheel so its really close to the spokes on the biggest cog) DieselnDust 1 Link to comment Share on other sites More sharing options...

DieselnDust Posted July 28, 2020 Share Ah I thought it was the lower pulley somehow Link to comment Share on other sites More sharing options...
Rocket-Boy Posted July 28, 2020 Share If it was me then I would just drill out and tap up to the next size bolt.Might not be the prettiest thing but would be fully functional. Link to comment Share on other sites More sharing options...
The Ouzo Posted July 28, 2020 Share If it was me then I would just drill out and tap up to the next size bolt.Might not be the prettiest thing but would be fully functional.wont work, the bolt passes through the pulley wheel, so that would mean drilling out the bushing of the pulley wheel to accommodate the thicker bolt., I'm not keen to do that with something that spins so fast.

Shebeen Posted July 28, 2020 Share otherwise you're looking for something like a chain ring bolt that fits into a sleve so can be flish both sides? Link to comment Share on other sites More sharing options...
