*PHIL* Posted May 16, 2007 Report Share Posted May 16, 2007 (edited) Hi all.Finally got my bike back after 2 weeks in some stinking shop.I'm trying to fit a Rohloff tensioner and as you can see from this photo its not gonna work!The guy in the shop moved the sprocket inwards for better chain alignment when there was no tensioner on there at all.Any ideas on what I can do?I would just move the sprocket back to where it was but then, the guy moved it for a reason, it wouldn't be a good chain line.CheersPHIL Edited May 18, 2007 by himynameisphil Quote Link to comment Share on other sites More sharing options...
Christophe' Posted May 16, 2007 Report Share Posted May 16, 2007 put the spacers the other way round, and u will prob also have to file some metal off the mech hanger to get the jocky perfectly aligned.only way u can get perfect chainline is if u get the spacers custom made.

TomN Posted May 16, 2007 Report Share Posted May 16, 2007 Longer BB i say and move the cog back forward aswell. Quote Link to comment Share on other sites More sharing options...
Ash-Kennard Posted May 16, 2007 Report Share Posted May 16, 2007 or if you used spacers from an old cassette. you could do what i did though and just bend your hanger inwards. Quote Link to comment Share on other sites More sharing options...

weebryan Posted May 16, 2007 Report Share Posted May 16, 2007 move the cog out by using s/s speed spacers dmr do them they have 3 one thick 2 thin or get a old casset and split it and use the spacers from it, also get a longer bottom bracket i had to get a 127mm for the caisso which done the job Quote Link to comment Share on other sites More sharing options...

basher Posted May 16, 2007 Report Share Posted May 16, 2007 Swap the spacers over first and see what the chain line is like if its totally off then, just get a set of spacers that is comprised of smaller ones and not a big and a small one then. With the smaller spacers you will be able to move the spacers around more and get a more accurate good chain line. Quote Link to comment Share on other sites More sharing options...
*PHIL* Posted May 16, 2007 Author Report Share Posted May 16, 2007 the two massive great spacers that are either side of your rear cog,,,one is narrower than the other.swap them so the cog is further towards the dropout simple realy yeah.. i actually suggested that in my first post and as i said it would give me bad chain alignment.ill try and swap them over tomorrow and see what happens..cheers for the help all Quote Link to comment Share on other sites More sharing options...
dave85 Posted May 16, 2007 Report Share Posted May 16, 2007 You could try bolting the Rohloff to the inside of the hanger rather than the outside. Looking at it, it may shift the chainline a bit further inwards, but it'll be better 2 or 3 mil in rather than 10 or 12 out. Quote Link to comment Share on other sites More sharing options...
Krisboats Posted May 16, 2007 Report Share Posted May 16, 2007 Will the rohloff arm not rub on his cassette lockring though edd? Quote Link to comment Share on other sites More sharing options...
dave85 Posted May 16, 2007 Report Share Posted May 16, 2007 Might be a bit tight, can't really see from that photo. Quote Link to comment Share on other sites More sharing options...

Christophe' Posted May 16, 2007 Report Share Posted May 16, 2007 still saying swap the cassete spacers and put some washers inbetween the rohloff and mech hanger to bulk it outwards.thats the bodge anyway, measure it on the monitor and see.

*PHIL* Posted May 17, 2007 Author Report Share Posted May 17, 2007 erm.... anyone know how to remove a sprocket? Quote Link to comment Share on other sites More sharing options...
RobinJI Posted May 17, 2007 Report Share Posted May 17, 2007 Chainwhip and Cassette tool. Can use 2 blocks of wood and a vice rather than a chainwhip on a singlespeed though. Just anything thats gunna hold the sprocket from turning backwards but not damage the sprocket. Quote Link to comment Share on other sites More sharing options...

*PHIL* Posted May 17, 2007 Author Report Share Posted May 17, 2007 Hey just thought I'd post here sayin I swapped over the spacers and now the rohloff is fitted and in a pretty good line with the sprocket.Overall chain line isn't too bad either, still quiet and that. But it doesn't skip anymore!! I can finally ride my bike.--------------The rear wheel is proper dished though (I think).Is there anyway to put a washer/spacer between the hub and dropout on the non drivetrain side and get a shorter spacer on the other with the sprocket?If this is unheard of then my wheel must be dished as it is too far over to the left. Brakes keep rubbing just on the left side.Once again thanks for all the advice.PHIL Quote Link to comment Share on other sites More sharing options...
dave85 Posted May 17, 2007 Report Share Posted May 17, 2007 and the rolhoff 'arm' isnt threaded. so what will it tighten too?then you will need a new nut and bolt?Put the bolt through from the hub side, through the rohloff arm and into the hanger Quote Link to comment Share on other sites More sharing options...
*PHIL* Posted May 17, 2007 Author Report Share Posted May 17, 2007 Put the bolt through from the hub side, through the rohloff arm and into the hanger oh yeah btw i tried this and it just wasn't happening. the rohloff wouldn't fit on inside because of the sprocket spacer.plus there was nothing to keep it from spinning all the way round... if you get what i mean Quote Link to comment Share on other sites More sharing options...
