I certainly can I'll get some as it gets made anyway.... probably a video too. Yep quite possibly, depends on the diameter of their bolt holes....I suppose it would be 46mm like a standard disc hub? If so then maybe not....as the inner ring ( lockring ) on some burns is 42mm... It would nearly definitely work with a custom cnc'd / routered one however

I'm just being cheap and drilling a standard 18t singlespeed cassette sprocket....but I'm sure I could find out where Steve gets his from...or London Fixie has some that were designed to take the IS disc mounting. That is very true Luke, like I said this is just a... 5 holes may as well put another 5 there as they fit nicely in between the spider If i ever made them I'd run 6 10.9 bolts probably. I'm not worried about the sproket giving out at all...after all disc rotors have massively more leverage, smaller bolts and shit loads of material removed from in between the holes E.g I'm definitely going to properly model this with a chain and sprockets as soon as I'm back at college if I've got enough time between doing end of year coursework Best case scenario is I'll have the first one finished and on the bike for a ride in Plymouth on Sunday where you can have a look if you wish Haha yeh it is pretty cool, love playing with the Mill and lathes to make this interesting shizzle Just aiming to make as much as possible for my project bike really, or at least modify it so I've put my own twist on it.

Fail....I can't stress test an assembly at home, but I can assure you nearly all the force is acting through the splines... Erm, I have this...but I don;t think it really shows anything as the crank isn't mounted, and the force is only perpendicular, not a cyclical torsional force. Got a picture below of the latest revision, but without the drilled holes, only the large scoop Cheers

Give me literally two mintues and I'll model one Without holes and with....

Hmm I suppose, although he bolts will be machined down so they aren't sticking out. The heatsink cloud9 uses the same m6 standard pitch bolts...and that never seems to be an issue? I appreciate they have more of them though I have a couple of other ideas, but I Guess the only way to find out is to test them really. I still have space to tap and thread 5 longer than usual chainring bolts through, so that's still an option. Any other comments please keep them coming I can model one in a mo...and yup less holey is no problem at all

RB designs lever...I think that version is the older style? Although you can get hold of them here : braking stuff Bikes look lush, incredible spec on all, pretty dengtastic. Gone are the days when that meant 11kg+ though Love the gold slate2 so much......really want one to replace the Coustellier

It's a definite possibility, I do have access to a CNC router that I could use The lockring fits fine actually, as the sprocket is spaced away from the cog. I'll show you a picture of the original actually drilled in real life Nope, tap straight into, but because of the scoop into the crank arm all the bolts can pass straight through. If this turns into an issue I may just have bolts going from the front side and neat little allen nuts on the t'other / normal chainring bolt style Sure If i can actually use the CNC router...which hopefully I wills and yep, that's no problem at all, I may change the design so it suits both anyway. Cheers man, appreciate the feedback from you all

Just do it...works well.

Interesting idea....I think I'd stick with roadie grip tape though, personally

Here we are...scooped and drilled 46grams according to solidworks. On target to be the lightest complete Burn setup with steel cog?

Tis alright...original but not the best way of going about it. I'd sandwich the booster as used by TNN.

From 180g ( Solidworks says 226g ) to a predicted mass of 76g ( bash only ) Thanks man, well I'll keep you posted... the only hard thing is lining up the drilling of the bash and cog to be honest....modding a cloud nine is very easy by comparison If you were to do that, I'd say fly cut the circles off...half ring it then drill straight through. Also, weight to be saved on the back too. Yup, I'm thinking about milling a channel round the front edge, kind of a scoop...and drilling in between the bolt holes. I'll model something up now to show you what I'm banging on about . 18T cassette chainring, drilled out to fit five 10.9 Hi-ten bolts. And yup, smallest size for 5-arm is 20t Yup... Bingo, but I reckon the cloud9 is wayyy too much overkill Hence stronger bolts, but less of them. Think disc rotor...6 m5 bolts with a 23cm lever acting on it...compared to 5 high tensile bolts with a 17cm lever. I know which I'd trust more

The UCI world championships?

Ew to rims on three counts...but bike looks nice and set-up pretty well

Right,..... basically I've turned into a bit of a weight fag now and have really started to try and ditch some pudge off the Coust ( 10.3 ). The obvious place to start was the crankset... a tanky set of Echo CNC's, Surly steel cog and Echo old bashring. After having a lil nose around I decided on either some Burns or Try-alls....as a mate had some burns on an old frame I want down that route. After a few hours and copious amounts of sweat and tears I finally managed to get them off, only to discover just how silly heavy those Pro trials bashes really are ( 180g ). So... either buy a TNN bash, or Heatsink. Trouble is neither fitted the bill.... the cloud 9 was a full ring , and the TNN were all steel and non-replaceable cog. So why not make my own? Decided to recycle the old bash as I couldn't find an easy way of making the spline without CAM routering it ( which is cheating ). Lots of milling, some careful drilling ( cog and bash ) and i should have a damned light, strong crankset if I don't balls it totally. Soo..... 5 bolt M6 design, 18t bolt on cog and a half bash....Below are all the models I made for it , and all the revisions that got it to the final stage. I realise that the bolts are the wrong size, as I later changed them, and the spline is wrong in the centre....but these were just reference models to see what It'd look like. I'll post up pics as I go through it, and some weights when I can be bothered 180g starting weight. Just the standard Pro trial bashring Same as above, just with the 5 holes drilled for the new, smaller 18t cog. Just after milling the excess to give a half ring kind of shape. Shows the rear with the original 5-arm mounting milled off. This is the final one, shows the bash has been fly-cut right down from 14mm profile to a lightweight 6mm. Final version, but assembled with cog and bolts. So far.... I've drilled the 5 mounting holes, but should get on the main milling job in the next couple of days. Any comments welcome, especially to make it look naice.

Depends where they crack...there's around 3 different places

Yeh Viz forks fo sho....bike looks naice

BB yolk has now been fully milled for the weight savingz Still looking a little rough though, will be sanded, polished, then wet 'n' dried. Bottom bracket shell has been professionally threaded and turned down.....still 3 slots to go in to save some weights Headtube has been taper turned, internally bored and milled....still two slots to go in though. Mark1 of my plastic prototype brake area Mark2 with milled down custom magura mounts ( think Echo TR/TNN, washerless )

New stock forks are being tested, or are en route at the moment

Adam is guilty of hot linking....

I'm sure Muel will be in here shortly to talk about his homebrew creation....that's what I'd do

Looks really good, incredibly clean
