1handedluke Posted August 6, 2007 Report Share Posted August 6, 2007 (edited) Hello guys, after the dilemma with my braking system never working, and use hydraulic isn't working, I'm deciding to give duel disc's ago, I've been looking at these Odyssey M2 levers, but to run 2 brake off one lever, I'm going to have to extend the lever so there is more power! also i don't understand the difference in cables! and why in my other topic he said about getting the road BB7? also because I've got a adamant A3 I'm going to have to build or buy a disc adapter, I believe I've seen them selling somewhere, but i can't remember!any help would be appreciated!thanks Luke Edited August 6, 2007 by 1handedluke Quote Link to comment Share on other sites More sharing options...
Brian Bleech Posted August 6, 2007 Report Share Posted August 6, 2007 Vee brakes need levers that pull more cable than Road/U Brakes/Cantilever brakes. MTB BB7s are designed for use with v brake levers, so the odyssey lever won't pull enough cable for it work properly. The road BB7 is designed for use with road levers*, which work the same as the M2 lever.*i have never used a road bb7 or modern road bike, so all this is an educated guess.

Muel Posted August 6, 2007 Report Share Posted August 6, 2007 I would go for twin hopes with a monty splitter if I were you mate. Quote Link to comment Share on other sites More sharing options...
Greetings Posted August 6, 2007 Report Share Posted August 6, 2007 I think Luke already tried using a splitter. This system would create lots of problems, like a very spongy lever and having to pull it right to the bars in order for the pads to touch the rotor. Using a closed system like the C2 lever might eliminate this problem, but will not give as much braking power as two BB7s. The main issue here is to have enough braking power to lock two wheels with one lever. So Luke's got to get the most powerful brakes he can, and those undoubtedly would be 8" BB7's. Secondly, if he can adjust them so the pads are in constant contact with the rotors but don't create a lot of drag, he could modify the lever to give much more mechanical advantage. I think Danny Swindlehurst welded a disc adaptor onto his GU, you might want to talk to him about that. Quote Link to comment Share on other sites More sharing options...
Tom_ Posted August 6, 2007 Report Share Posted August 6, 2007 yea, vee brakes pull less cable (maybe more i cant remeber, either way its a different cable pull) to lock the brake than u brakes (road and bmx) so since the m2 lever is a bmx lever designed for a u brake you will need to run a road version of the bb7 so that the brake doesnt feel crap and spongey.the oddysey comes in a long version i think? for flatland i guess thats a pretty long lever, although you might need somthing longer to pull both brakes without loads of effort.I have seen quite a few sucsessfull disk mounts on non disk deng frames, shouldnt be tooo hard to do.

1handedluke Posted August 6, 2007 Author Report Share Posted August 6, 2007 what about one of these jobbys! linky!would i be able to get this to work on a avid lever? then just extend the lever? Quote Link to comment Share on other sites More sharing options...
Fixed Pants™ Posted August 6, 2007 Report Share Posted August 6, 2007 Good find Luke, that looks perfect for the job!I'd say go for it, no harm in trying.Good luck fella. Quote Link to comment Share on other sites More sharing options...
JT! Posted August 7, 2007 Report Share Posted August 7, 2007 What setup are you using now and what are it's problems? Quote Link to comment Share on other sites More sharing options...
Muel Posted August 7, 2007 Report Share Posted August 7, 2007 I'd go for the primo pervert thing matey. Looks like you can adjust the cables while on the fly, and also it can roll so they don't have to be exactly the same legnth.Go for it, worth a try, then you can use an xtr lever or whatever.

Captain Scarlet Posted August 7, 2007 Report Share Posted August 7, 2007 What setup are you using now and what are it's problems?Check Lukes Adamant in the bike pictures thread.He has two seperate levers on one side, so obviously its gonna be a bitch to pull both at the same time, therfore only one brake can be used at a time. (I think).I had an idea, what about a giro kind of system?, that works as it splits one cable into two to go into the giro so the brake can be transferred to the back and still work whilst the handle bars are being spun.Adopting that kind of idea, as BB7's only need one cable to work, why not just try the little giro thing and send one cable to the front?Surely that should work as the splitter is comonly used on BMX's that wish to have giro installed.

JT! Posted August 7, 2007 Report Share Posted August 7, 2007 (edited) Would a couple of hope mono trials work? If you used a splitter?Or would using a splitter just mess up the open system? Edited August 7, 2007 by JT! Quote Link to comment Share on other sites More sharing options...
Has anyone seen my shoe? Posted August 7, 2007 Report Share Posted August 7, 2007 Cant use hyrdo brakes on one lever as it makes it super spongey. Quote Link to comment Share on other sites More sharing options...
RobinJI Posted August 7, 2007 Report Share Posted August 7, 2007 Yeah, that primo pervert thing looks ideal for what you want. to be honest I dont see why you couldn't use a Vee on the back to save the complication of getting the mount, as long as it was a stiff vee with a good booster it should be fine.

Fixed Pants™ Posted August 9, 2007 Report Share Posted August 9, 2007 (edited) Anyone remember the 6 piston disc brake a while back? It's lever must have a huge resivoir, which would be enough to power 2 discs.But, the thing Tart found you looks quite promising, would probably beast up a normal magura for some serious breaking.

Elmo =) Posted August 11, 2007 Report Share Posted August 11, 2007 i know you have probaly thought about it but i think it might be possible to use a giro splitter sort of thing, link << that might do the trick. Quote Link to comment Share on other sites More sharing options...
gianttrials Posted August 11, 2007 Report Share Posted August 11, 2007 (edited) Cant use hyrdo brakes on one lever as it makes it super spongey.not neccesarily, if the hosing length from the t-adapter (cross-over) is the same for each cylinder then it would work at even pull an should prevent spongeyness, in theory (i think) Edited August 11, 2007 by gianttrials Quote Link to comment Share on other sites More sharing options...
Has anyone seen my shoe? Posted August 11, 2007 Report Share Posted August 11, 2007 It really isnt, i've seen Luke try to use two brakes of one stand lever. It doesn't work! Otherwise he would have stuck with it.The best soloution at the moment is two seperate brakes on one side. Quote Link to comment Share on other sites More sharing options...
Greetings Posted August 11, 2007 Report Share Posted August 11, 2007 Please don't get hydro brakes, it just won't work properly. Double 8" BB7's set up with minimal drag (both pads touching the disc) and a bmx lever with an extended lever blade, you can't go wrong with that and it will be super powerful!
