Andy P Posted May 13, 2010 Report Share Posted May 13, 2010 Basically, I remember seeing a website where you could buy various frame components and I fancy welding some 4 bolt brake mounts to the back of some steel disk only forks. Anyone know which website it was? Failing that I'll just make some.... Cheers! Quote Link to comment Share on other sites More sharing options...

psycholist Posted May 13, 2010 Report Share Posted May 13, 2010 I wouldn't weld the brake mounts to the back of the fork legs though. For normal use the back of the fork legs is in tension, so the chance of causing a fatigue crack from where the brake mounts are welded is quite high. I had a set of Echo urbans with the brake mounts on the back snap after about 9 months - many people snapped them a lot faster - and these were supposed to be designed from the factory for trials loads.It's safer to put them on the front of the fork.

I've cracked the 08 model that had 4 bold mount on the front, just were the mount was. Don't recommend welding anything onto a fork, if you want to live, but that just my opinion.

Riding along normally puts very little stress on the forks, it depends more if you gaps to front or tap a lot, or hook/slap more. In terms of braking power, it's supposedly better on the back of the fork leg. Quote Link to comment Share on other sites More sharing options...
Mat Smith!! Posted May 13, 2010 Report Share Posted May 13, 2010 ? they look shit like theres 2mm of thread, and the bolts are worthless aswell, are they a 5mm head? so they wont fit in the groves of your acctual magura mounts. Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted May 13, 2010 Report Share Posted May 13, 2010 They're steel, so the shorter thread won't be an issue Quote Link to comment Share on other sites More sharing options...
Muel Posted May 13, 2010 Report Share Posted May 13, 2010 Never managed to strip a thread out of any I have had, but yeh those bolts are utter shite. Quote Link to comment Share on other sites More sharing options...
Revolver Posted May 13, 2010 Report Share Posted May 13, 2010 They're steel, so the shorter thread won't be an issue My leeson came with those on the back. One hole was stripped, one was nearly stripped, and I think others have stripped since. Quote Link to comment Share on other sites More sharing options...

Mounts on the back should be better, as you apply the brake, twisting the brake and mounts into the wheel rather than outwards and away from the fork as if the mounts were on the front. My Urbans with maggy mounts on the front have cracked to the point I won't ride them any more after just over 2 months of use. Those braze on mounts should be fine, they use them for the Pashley bikes don't they? Were fine when i had mine. Quote Link to comment Share on other sites More sharing options...

I think he is mainly referring to the greater stress running through the forks when mounted on the back, leading to a much short life of the forks. I personally would have reverse mounts any day of the week, and run the risk of shorter fork life. Quote Link to comment Share on other sites More sharing options...
psycholist Posted May 14, 2010 Report Share Posted May 14, 2010 (edited) I agree that brake mounts on the back of the fork are better for out and out braking performance. The problem arises because most of a fork's time is spent with the rider's weight putting tension in the material at the back of the fork legs. I can neither hook or tap and my fork failed anyway (Snapped completely through both legs) landing off a drop about 6" high. Fatigue cracks need tensile loads to start, so the less you interfere with the grain structure in the metal and the shape of the back of the legs the longer the fork will last. I've had other forks fail through either bending forwards or through cracks forming at the back of the fork legs even without brake mounts being welded there, but they were steel forks, they gave plenty of warning and I'd been using them for over 2 years in all cases...
