the666ers Posted March 7, 2005 Report Share Posted March 7, 2005 Ok I have come across a problem in building up my bike. On the ashton forks, with the dual boss part for 24/26 inch forks, when you run them for 24 with the studs on the lower brackets, the brake caliper cannot go all the way on without hitting the top one. There is no way I am changing forks (having just had them professionally sprayed) or taking a grinder to the top mounts, so I was wondering if anyone has any solutions.... I also can't run a disc as I don't have a disc hub. Having a quick thought, this would fix it (quick artists impression) but I've neither the materials or tools to make it... It would need to be 1.3-1.5cm deep to enable the calipers to clear the forks... Any help or suggestions appreciated. James Quote Link to comment Share on other sites More sharing options...
tank_rider Posted March 7, 2005 Report Share Posted March 7, 2005 what calliper are you trying to use? it seems a bit silly to put brake mounts on for 24" forks if you cant use any/many brakes with them (N) Quote Link to comment Share on other sites More sharing options...
Tomm Posted March 7, 2005 Report Share Posted March 7, 2005 Hmmm, Ashton doesn't seem to be too hot at making forks does he? Anyway, you need 1-2mm more clearance, right? Can you just use a simple washer under the brake? If it's not LX/XT/XTR brake, then I don't think you NEED the little stud to be in the little hole.

the666ers Posted March 7, 2005 Author Report Share Posted March 7, 2005 It's a XTR vee, so it's about as generic as the come.... Shit design i'm thinking, I can't believe this hasn't come up before (N) James Quote Link to comment Share on other sites More sharing options...
The Dude Posted March 7, 2005 Report Share Posted March 7, 2005 by the looks of things your running a V. you could do that or get a magura washer, and cut a little slit into it witha hacksaw for the spring to sit in. that will bring it up 3mm and keep the tension on the spring.

But that's certainly not a bad idea, although it might be a bit fiddly to set up (You'd almost need to "glue" the washer onto the forks, to hold it in the right position) Quote Link to comment Share on other sites More sharing options...

James ← It's not just about not clearing. Its fookin miles off. It needs to come out about 10mm to clear (just measured it) James Quote Link to comment Share on other sites More sharing options...
Fishwog Posted March 8, 2005 Report Share Posted March 8, 2005 (edited) My friend has this exact problem, he found some realy old gay v-brake (which although is decrepid and ugly, works really well!) that has a strange shape and spacing, and it worked, but yeah it is really shit (N) Edited March 8, 2005 by Fishwog Quote Link to comment Share on other sites More sharing options...
Brisa Posted March 8, 2005 Report Share Posted March 8, 2005 I think this happened to Mitch on his ashton. Result was a brake without all that parallel push stuff... Quote Link to comment Share on other sites More sharing options...
SebJT Posted March 8, 2005 Report Share Posted March 8, 2005 I have something at home that would fix that perfectly... like exactly as you have drawn. I had a pair of the mission v brake adapters, but they were far too long, so i cut them in half. Making them about the size you want. Youd have to drill a deeper hole in one of the spring holes, so you can put a post in it to hold it in place. Im at uni now, so cant really get them to you.. Although if you are interested in them i might be able to get my brother to find them, if not im home in 2 weeks... Theyre also available from bikedock, so you could just buy some from there and modify them. Seb Quote Link to comment Share on other sites More sharing options...
the666ers Posted March 8, 2005 Author Report Share Posted March 8, 2005 I would be eternally greatful if you could send me those. They look as though I could definately sort the problem with a bit of handy work. Let me know if you manage to find them, I'll wing some great porn your way or a bit of money or whatever if you like. Thanks a lot James Quote Link to comment Share on other sites More sharing options...
Brisa Posted March 8, 2005 Report Share Posted March 8, 2005 I have used some mission vee adaptors and my brake was horrible, wasnt even suitable for the front. The bosses that go in only have a thread the same size as a four bolt anyway. Im assuming the ashtons mounts are the same as any canti mount? Your best solution wouls be to go for a sd7, ultimate etc... Quote Link to comment Share on other sites More sharing options...
the666ers Posted March 8, 2005 Author Report Share Posted March 8, 2005 I'm only using it to space it out, I'd rather try this than go spending loads of money on a new brake if theres a chance this will work. James Quote Link to comment Share on other sites More sharing options...
Brisa Posted March 8, 2005 Report Share Posted March 8, 2005 ah, get you now. Thought you were gonna try and use the posts that come with the mission things. You will need to drill the inside of the spacer out to fit your own posts.. Quote Link to comment Share on other sites More sharing options...
the666ers Posted March 8, 2005 Author Report Share Posted March 8, 2005 Yup, I'm pretty sure of what I'll need to do, I'll let people know how it goes. James Quote Link to comment Share on other sites More sharing options...
Bucky Posted March 8, 2005 Report Share Posted March 8, 2005 (edited) :angry: :angry:" :blink: in stead of setting the brake further away from the forks so it flex's more why dont you just get rid of the offending materials??? IE: hack the useless bits of with the biggest angle grinder or saw you can find!!!!! Proper Job!!!! :angry: Edited March 8, 2005 by Bucky Quote Link to comment Share on other sites More sharing options...

the666ers Posted March 8, 2005 Author Report Share Posted March 8, 2005 It's fouling the upper canti boss mount. Imagine the studs on the lower ones, and the calipers hitting the top ones. Quote Link to comment Share on other sites More sharing options...

george_seamons Posted March 9, 2005 Report Share Posted March 9, 2005 Can't you just unscrew them? ...or am I getting the wrong end of the stick? :blink: Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted March 9, 2005 Report Share Posted March 9, 2005 ...or am I getting the wrong end of the stick? :blink: ← :angry: You move the stud to the bottom hole for 24" wheels... which means the brake arm fouls the top half of that huge chunk of alloy.

The Foamoi Refresher Posted March 9, 2005 Report Share Posted March 9, 2005 use an sd7, it works fine i know this because i am running one at the moment on the front of my ashton with ashton forks, on the lowers, luisio Quote Link to comment Share on other sites More sharing options...
