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

to translate the product of the translator... Click below, on the link there is a better translator that I'm showing you because people aren't understanding what you say.

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

Tensile 60 click out of personal experience...Echo SL from what everyone else says

Exactly what Kris said ( by the way I met you on Sunday morning when you were walking the section

Looks really good, incredibly clean

Meh I still like inch-pinching....was considering trying it on a mod, but now everyones jumped on the bandwagon I don't really see the point in putting the riding time into releasing a video on it Brakes for the forseeable future for me

Probably Novice or Intermediate if you've been riding a year and a half

New Onza mod frames are super cheap and so nicely made Got to have a bounce on a few of them on sunday, very impressed by build quality and how they'd specced them. The weights are incredibly low, but with U6 they'll last a decent time without shitting themselves

No real performance benefit...as most people have said before the Ultimate is massively overpriced, you'd be better off buying some SD7 arms or better still keeping the HS33

Anodised seems to give the best performance on smooth...however I'd personally only use a grind

All setup and preference....most frames can be made to feel " nice" although some more than others.

2004 are better in sooo many ways. Get one, bang an RB designs lever on it and you're sorted

I wouldn't bothe to be honest....maybe some garden hose or similar on the chainstay could work though.
