flas12345 Posted March 5, 2007 Report Share Posted March 5, 2007 its peoples own personal preference really. some might like to have a disk on the rear aswell as on te front or some might want to have a magura on the rear. all depends on wha they prefer best.cheers lou.

Bearded Midget Posted March 5, 2007 Report Share Posted March 5, 2007 most frames dont have rear disk mountsmost people dont want to spend that much on both diskssome people are cautious wether or not they will bend it on a wall if they smack ita few reasons reli lol Quote Link to comment Share on other sites More sharing options...

011001000110010101110010 Posted March 5, 2007 Report Share Posted March 5, 2007 The problem with a rear disc is all the force it applies to the rest of the frame. If the frame isnt upto it, it will fell horrible and flexy and eventually snap/crack. But if you can get a frame that will handle it, then a rear disc is a waaay better option than a crummy magura.

spmcfadden Posted March 5, 2007 Report Share Posted March 5, 2007 Not had any experience with rear discs but it would stress the left hand side of the frame a lot more obviously, so a light competition frame could have its life shortened.As for bending the rotor, if you don't hit your mech much then shouldn't hit the rotor much either.

Muel Posted March 5, 2007 Report Share Posted March 5, 2007 Not had any experience with rear discs but it would stress the left hand side of the frame a lot more obviously, so a light competition frame could have its life shortened.I agree, but my mate has a 221PR with dual hope mono trials, in his first set of wheels it nearly pulled all the spokes out of the rim. I think that this is because a disk will completely stop the hub from mving, but the rim can still move and twist as the spokes bend and strech.

I think that this is because a disk will completely stop the hub from mving, but the rim can still move and twist as the spokes bend and strech.What utter bull!I run dual disc, am 6'6'' and weigh just over 14 stone. My disc hold perfectly and never have wheel problems (apart for some unlucky hub problems at the moment)KOT MS 2 frames really hold up to the discs and just a good strong wheel build. Give all your spokes and extra turn to stop any flex.Rob Quote Link to comment Share on other sites More sharing options...
spmcfadden Posted March 5, 2007 Report Share Posted March 5, 2007 Sounds right. Force applied to the wheel by tyre and rim, calliper clamps the rotor stopping hub moving, so rotating force transfers through the spokes twisting them. Then either snap the spoke or rip it out of the hub flange. With the rim brakes stopping the rim directly stops this problem. Also with discs only being on one side it stresses the disc side spokes more so twists and feels flexy as has been mentioned.Some hubs (like the Mavic Deemax) have the spokes coming into the hub straight without the curve on the spoke, stops the force concentration on the curve of the spoke near the flange to stop them snapping there. Never seen any hub like that on a trials bike though! Quote Link to comment Share on other sites More sharing options...

Not sure if you have seen them in the UK but we had alot of them out here in Australia a while ago.www.biketrialsaustralia.com has a picture of one under products I think.

trialsboy_06 Posted March 6, 2007 Report Share Posted March 6, 2007 hi most people like to run a rear maggie because they are more responsive. but rear disk is good for comp. Quote Link to comment Share on other sites More sharing options...
Dave Lowe Posted March 6, 2007 Report Share Posted March 6, 2007 The problem with a rear disc is all the force it applies to the rest of the frame.

But if you can get a frame that will handle it, then a rear disc is a waaay better option than a crummy magura.I agree with you there, there is no doubt about it the disc is better, that’s why they put them on cars, busses, lorries, motor bikes, aircraft etc, but like it says above the frame has to be up to it and the rear wheel, as for bending them well I side hop both ways and in 4 or 5 years I have bent one and I was able to bend it back.Maybe it’s personal preference or maybe its people being scared of being different.
