You don't need to be an 'investor' to invest in Singletrack: 6 days left: 95% of target - Find out more
I was trying to remove the inner chainring to try 1*10 and I sightly mangled one of the inner chain ring bolts on my new SLX cranks (my fault for using what I thought was the correct tool, rather than read the instructions). I drilled the bolt head off but couldn't get the full bolt out. Is it possible/safe to only use the the other 3 to hold it on and ride it, or will I die?
Any help appreciated
Thanks,
Dave
no - i tried once - under heavy chain tension the ring folded badly in a V at that point
If you've only got 1 chainring won't it be in the middle position, so inner bolt mangling irrelevant?
Edit: I'm surprised you're not dead already
I've seen one fold like that too. Some particularly stiff rings may work but it'll be a bit of a chance.
also instead of trying to bodge - why not take it to a shop to repair your screw up - its a REALLY easy fix with the right tools - if your near aberdeen im back next week and will do it for you !
You won't die, but the chainring might well. I find it very easy to bend or snap 4 ring chainrings and I'm a lightweight wimp.
As mentioned above, should be easy to fix.
Thanks all.
