Greetings Posted March 27, 2007 Author Report Share Posted March 27, 2007 (edited) why not just run a mtb hub built on a 20" rim....how do you mount a brake then?if you have any ideas please write them down by the looks of things you haven't read the 1st post...besides, getting a rear hub would cost me money. got a hardly used funn hub with a disc mount, screw on sprocket and funbolts in return for a set of pads - as i wrote in the 1st post, i don't want to spend any more money....

SCOTTY___ Posted March 29, 2007 Report Share Posted March 29, 2007 (edited) Posting for Jake:219M stdZOO old style bars221Ti 740And a close-up:The ones shown on the pic are for 219M bars which have a thicker sidewall. Bottom one is for 720mm and top one for 740mmThat would have to be a hell of a tight fit...did it take some bish boshing to get them in? i ahve some old monty bars in the shed i may consider doing it to Also steel or a nice grade of alloy to make them from? from the pic looks like steel.

Greetings Posted March 30, 2007 Author Report Share Posted March 30, 2007 I think they're 7075 alu, that's what I asked for but it's apparently hard to get so it could well be PA6 which was my 2nd choice.It is a tight fit, I had to put them on a lathe at home to get them exactly right. Then it was just a WD40 + hammer job. Quote Link to comment Share on other sites More sharing options...

Greetings Posted April 1, 2007 Author Report Share Posted April 1, 2007 QUOTE(deanie-b @ Apr 1 2007, 11:03 AM) ←Any further progress Inur?Looking forward to the finished product Just need to build the rear wheel which will allow me to finish off the brake mount and set everything up. Then it's just a matter of getting a screw on sprocket, freewheel and new brake pads for a Mono Trial. This would have been finished ages ago, I was planning on changing frames but I'm still riding the Adamant. Quote Link to comment Share on other sites More sharing options...
basher Posted April 1, 2007 Report Share Posted April 1, 2007 How have you attached the disk mount to the frame, as theres no whole like mods for the bolt for snail cams. So are you just using the axel bolts as a fixing point. Quote Link to comment Share on other sites More sharing options...

Greetings Posted April 15, 2007 Author Report Share Posted April 15, 2007 Getting most of my parts tomorrow - spokes to build up my wheel, screw on sprocket, a freewheel and brake pads.Got an exam on Tuesday so I'll build it up after that, just need an ISIS bb now Quote Link to comment Share on other sites More sharing options...
Greetings Posted April 17, 2007 Author Report Share Posted April 17, 2007 Let the battle begin!Expect to see some results in the next few hours Unless I'll find an easy way of removing an ACS freewheel, I won't be riding it yet. Quote Link to comment Share on other sites More sharing options...

Greetings Posted April 17, 2007 Author Report Share Posted April 17, 2007 Current progress:Rear wheel builtAdaptor mounted onto the frameHub spacing problem solvedChain line problem solvedStill to do:Remove chainring off crank and replace with ACS (temporary, I hope it can be easily removed as i've got nationals this weekend)Bleed front brakeSet the chain upMount front brakeCheck everythingMount rear brakeThen it's just a matter of cutting the adaptor down to a small size, doing some cosmetics and painting it black.

paul@rettotrials Posted April 17, 2007 Report Share Posted April 17, 2007 that looks mint, i bet it will be a beast to ride. Quote Link to comment Share on other sites More sharing options...
Barbra Posted April 17, 2007 Report Share Posted April 17, 2007 (edited) oh man, get some riding pics. And a detailed explanation on how it rides! looks truly awsomeEDIT: And a video Edited April 17, 2007 by Barber Quote Link to comment Share on other sites More sharing options...
Greetings Posted April 17, 2007 Author Report Share Posted April 17, 2007 Alright then. I have basically finished what you can call the first attempt. I now know what the problems with this setup are (frankly speaking I was expecting them).So yes, I have ridden it, just a few sidehops and things that are not heavy on the drivetrain.The main problem is the stiffness of the setup. There are lots of washers, this thick adaptor which all add up to 20mm (the hub I'm running is 115mm). I wasn't expecting it to work perfectly first time but the hub will definitely need a serious modification. Basically I will need to make a really massive rear 135mm axle with Profile-sized funbolts. And to get that in, I'll need to change the bearings as the inner diameter is too small for a thicker than 10mm axle. This is all because when I press the cranks, the wheel shifts to the left causing immense drag on the brake. It's a bit difficult to sum up how this rides as I've only been on it for 15 minutes. The position is exactly the same as previously on 26", it also feels really long and close to a stock. For me that's perfect since I'm not a fan of mods anymore. The bike is quite strange on the rear wheel, a bit like a pogo-stick. It's also too long - not in terms of cockpit room but for instance when you do a pigeon or something (please let's not argue about what it's called ), you expect the rear wheel to land on the object but it's just not there. Meh, maybe I'm just not used to it, after all the Python has longer chainstays.Here's a pic of it built up, worked my way up to 6 pallets but it's quite difficult to do anything when you know the brake will lock up when you kick the pedal.Going back to 26" wheels now, got the 1st round of nationals this weekend. I think it's a matter of 2 weeks and the 20" will be in full working order again, but with a really stiff wheel/brake setup. Quote Link to comment Share on other sites More sharing options...

Bionic Balls Posted April 18, 2007 Report Share Posted April 18, 2007 surely an old 135mm fixed hub would make your life sooo much easier!like a welded deore?good effort though! Quote Link to comment Share on other sites More sharing options...
