Rich Posted May 4, 2009 Report Share Posted May 4, 2009 Hi All,After not riding for about 3 or 4 years I am trying to get back into riding. I recently replaced my old cracked forks with some Trial Tech ones. This has caused a problem with my front break though. As the new forks are wider than my old forks and I am using a narrow xc rim my maguras are not close enough to the rim. When I pull the front break the pads do hit after pulling the lever a long way, but the power is pathetic, I cant even lock it using 2 fingers! I was wondering what the solution to this would be, Im hoping I dont have to buy a new rim as the one ive got is reasonably new and in good condition. I've looked at the offset 4 bolt magura mounts but I dont think they would help me move the pads closer to the wheel as the "L" shape of the slave cylinders wont be able to move past the mounts to take advantage of the offset (hope that makes sense).I guess I will have to buy a new wider rim but thought id check to see if theres a cheaper solution!? I'd forgotten how expensive trials can be, you buy one thing and then it turns out you need another!Thanks for any help. Quote Link to comment Share on other sites More sharing options...
fatty r Posted May 4, 2009 Report Share Posted May 4, 2009 hey man there is a solution which involves gettin a pair of old pads and removing the brakeing material from the backings. Then glue the backings onto the backings of the pads that you are useing this will move your pads in a further few mill closer to your rim. Make sure you glue the backings on good though hope this has helped Quote Link to comment Share on other sites More sharing options...
Mikee Posted May 4, 2009 Report Share Posted May 4, 2009 (edited) I guess I will have to buy a new wider rim but thought id check to see if theres a cheaper solution!? I'd forgotten how expensive trials can be, you buy one thing and then it turns out you need another!I think a new rim will be best. Have a look on ebay and see if you can find a cheap rim going. Or if you can wait untill you get validated, have a look in the forsale section. These are probably your best bets if you want to save yourself some money.

Cowman.S Posted May 5, 2009 Report Share Posted May 5, 2009 i agree a new rim would do the trick, however it could be costly for a new rim and a wheel re-build, up to you mate Quote Link to comment Share on other sites More sharing options...
Rich Posted May 5, 2009 Author Report Share Posted May 5, 2009 Thanks for the replies. I think the new rim option is my best bet then, i'll have a look on ebay and hopefully I can sell my current front wheel so it doesn't hurt my wallet as much Hope to be riding again in the next few weeks!Cheers Quote Link to comment Share on other sites More sharing options...

Alex Dark Posted May 10, 2009 Report Share Posted May 10, 2009 Get an Echo Tr 26" front wheel from Tarty-bikes rrp: £ 77.32 .ew, no...i say get a tryall front rim and get that built onto your current wheelOr, for a quick bodge...screw an old pad backing using some short woodscrews to your current pads > thus extending the pads outwards Quote Link to comment Share on other sites More sharing options...
Ben John-Hynes Posted May 10, 2009 Report Share Posted May 10, 2009 (edited) Explain why you can't use offset mounts? You got the TPA all the way in? Is it a smooth rim? If so, maybe buy some new(full life) pads? Edited May 10, 2009 by Ben John-Hynes Quote Link to comment Share on other sites More sharing options...
Simpson Posted May 10, 2009 Report Share Posted May 10, 2009 2 Solutions. 1 - Magura overbleed techniquie. - so your pistons stick out before you pull the brake. 2 - get some old power pad backings, cut off the material, screw the backings to the back of your pads your using.

Rich Posted May 10, 2009 Author Report Share Posted May 10, 2009 Get an Echo Tr 26" front wheel from Tarty-bikes rrp: £ 77.32 .Hmm I had a look at that but ive just spend £150 quid on bike parts already, not eager to spend another £80!Explain why you can't use offset mounts? You got the TPA all the way in? Is it a smooth rim? If so, maybe buy some new(full life) pads?Because of the shape of the offset mounts the slave cylinder won't be able to move any closer to the rim, only further away (if the offset mounts are positioned the right way). Tried to explain it in my first post, a diagram would be easier! I have the TPA all the way in (well the TPA broke years ago, using the TPA bolt bodge on both levers!). It's a smooth rim and the pads are pretty new. Its just because ive got such a narrow rim, trials parts have moved on since I last rode!2 Solutions. 1 - Magura overbleed techniquie. - so your pistons stick out before you pull the brake. 2 - get some old power pad backings, cut off the material, screw the backings to the back of your pads your using.The overbleed technique sounds promising, I was hoping something like that would be possible. How is it done step by step? Been a while since I last bled my brakes...What are power pad backings, do you think any old magura pad would do?Cheers Quote Link to comment Share on other sites More sharing options...
Jackibrap Posted May 10, 2009 Report Share Posted May 10, 2009 Take a look on the freecycle part of the forum. I'm sure theres a 26" rim on there. And you only need to pay postage. Quote Link to comment Share on other sites More sharing options...

Been a while since I last bled my brakes...Urm just screw the plasic backings, onto the back of the backings of the pads you wanna use. Overbleed is a long winded worded explanation, basically, do a bath bleed with the lever blade off, pop out the piston, do up the bolts then push the piston in. Sure someone will explain it more i cbb right now. Quote Link to comment Share on other sites More sharing options...
