Archie H Posted November 26, 2017 Report Share Posted November 26, 2017 How much is it actually rubbing by? Does the wheel not move at all or is there just a lot of friction from it? If it is the second one then you could just spin the wheel for a while and let the disc sort of eat away at the caliper. Might weaken it but it may be better then grinding down bolts a lot which could snap and leave you in a tricky position. Or carefully grind or file down the edge of the disc so it doesn't rub. Best of luck anyway. Quote Link to comment Share on other sites More sharing options...
Hoba Posted November 26, 2017 Author Report Share Posted November 26, 2017 (edited) I think the bolt will hold better than it looks. 6 hours ago, Archie H said: How much is it actually rubbing by?

I found a shop in switzerland, they have a 173mm hope rotor in stock:https://www.trendcycles.ch/shop/shop/Bremsen_HOPE_Ersatzteile/Bremsscheibe_HOPE_Trial_Zone_173mm/de/2/1722 Can i use this? Its 52 Euro without shipping :/ Another alternative is, i get myself a shimano IS to IS adaptor for a 203mm rotor and than install a normal 200mm rotor.

Luke Rainbird Posted November 26, 2017 Report Share Posted November 26, 2017 Sod paying that much for one rotor - draw it up and have it laser/water cut. Hell, you get get a dozen of them for that money But yes, that should do the trick Quote Link to comment Share on other sites More sharing options...

Can you get a 200mm rotor? I thought they were all 203 as standard? Would you not have the same problem but with a bigger rotor? One idea though is that you could get a bigger rotor and get a bespoke IS to IS adapter made up if you know someone who can do that sort of stuff. Might be easier than milling you current rotor down.

grenosteve Posted November 27, 2017 Report Share Posted November 27, 2017 Take the caliper off, and get someone to spin the back wheel while you hold a file on the edge of the rotor. Take off just enough... Still a bit of a bodge, but safer than filed down bolts... Quote Link to comment Share on other sites More sharing options...

The plain (non threaded) part of the bolt hasn't changed thickness, it's the same as the minor thread diameter of the standard bolt Quote Link to comment Share on other sites More sharing options...
Ross McArthur Posted November 28, 2017 Report Share Posted November 28, 2017 Even if that was in fact "ok", there is a high chance of the calliper drifting under load and pulling itself closer to the frame, and in turn making the calliper rub.

AdamR28 Posted November 28, 2017 Report Share Posted November 28, 2017 I guess so in theory, but in practice it doesn't shift. In my experience the bolt doesn't fit tight into the hole on the frame normally anyway, so I guess this is no different? Quote Link to comment Share on other sites More sharing options...
Mark W Posted November 28, 2017 Report Share Posted November 28, 2017 Especially true in frames that have slotted IS mounts. Quote Link to comment Share on other sites More sharing options...
Daviesdt Posted November 28, 2017 Report Share Posted November 28, 2017 Removing threads on bolts is fine so long as you don't actually reduce the shank diameter. Quote Link to comment Share on other sites More sharing options...
