What impresses me is that it must have been so dark you couldn't set up the focus yet he could still do all that. He must eat lots of carrots.

I can't see any reason why frames shouldn't be equipped with disc mounts. There are quite a few good designs like the Modulo, Simtra and BT which are super beefy. I wouldn't trust Kot though or the ridiculous mounts the Limey had which would probably snap from just looking at them. Here's a quick explanation of the basic forces that act on a disc mount, I repeat REALLY BASIC. In a design like this, there are two stress areas. One is the magura mount and the other is the dropout and hub axle. The adaptor's main "pivot" is the hub axle and the dropout. It rests on the frame and the hub at the same time which are both very strong parts of the bike as long as they're not of shit quality. Any HD King or Profile hub will do the job. The other stress area is the magura mount. Due to there being a really small leverage (marked as the blue and dark yellow line) the force acting on the magura mounts is very small. The angle of the force is also very flat, so it's not pulling the screws out but actually using them as something to rest on. With rim brakes, the threads are being pulled out each time you break and yet they're fine. Here's another mount which has proven to work well, the Monty PR/Ti type. It's placed directly on the dropout which means it's strong within that area but puts a lot of stress on the top and bottom tube of the chainstay. The force is pulling the mount upwards at a large angle but yet it's fine. Luckily, the angle between the tubes is quite large which makes the design stronger. It's additionally supported by a bar which transfers the force onto the bottom tube as well. (Thanks Jake for the pic) Simtra, flat force and a beefy design, perfect to cope with the extra leverage a 26" gives. I don't quite trust the KOT design but I think it's good. The dropout and disc tab is one CNC element which means there are no weak points between the dropout which is the pivot point of the disc tabs, and the mounts themselves. Additionally, theres a tube between the top and bottom one which acts as extra support. The welds themselves would probably be the weakest element in this design but with a large weld area they are no doubt stronger than the tubing itself. It's actually the tubing I would worry about, Kot frames are a bit too light. Alright then. A comparison of the two designs. The standard brake mount is mounted on the top tube which essentially is a long lever, pivoting on the hub and supported by the bb and seat tube. Then you've got the screw-on, which is mounted near the hub axle and on the DM mounts. At the bottom of this pic, there are 2 black lines. The shorter the line, the more stress is put on the frame. The short line represents the traditional mounts, the long line represents the screw-on Wally and I made. To sum up, the closer the mount to the bb, the stronger the design will be - and that's why we hardly ever have problems with frames cracking because of Magura 4-bolt mounts. So why don't companies make adaptors like ours? Because there's just no point, what is currently in production is good enough. And last of all, the good thing about these screw-on adaptors we made is that they're MUCH more likely to bend/break than the frame. And as making one from scratch takes only about 3 hours using crude tools, you can't loose. The next step is to get the design right and have one cut out CNC from aluminum. Not only will it be lighter, the saved weight can go into making the adaptor stronger and stiffer. Aluminum is more brittle than steel and up to a point will be stiffer as well if treated appropriately. This is probably going to be a FAQ soon as more and more people are getting dual disc on non-disc frames. I'll be making my adamant dual disc this year but that will involve drilling the frame etc. The ideal setup for an adaptor like this is a 26" mod with narrow hub spacing. Personally, I'm not quite sure if an adaptor like this will work on a stock without extra support from the tubing, meaning it would have to be screwed down to the frame in places other than just the Magura mount.

Awesome video, loved the hooks after 1:50

As far as I remember, motorbike trials was under strong influence of bike trials at one stage. In L&B they talk about a bt rider who went over to motorbike trials and completely changed the sport introducing static techniques which he had learned while riding bt.

oh come on... he used a board for more bounce, the front wheel was a good few inches lower and the board itself was at least 2" thick unless you're talking about something else -

Theoretically yes, but I've never seen any rider do the lines Danny does. Whereas I've seen Neil and CLS doing Damons lines (and vice versa). Who is more special, a rider who is unique, or a very good rider who can sidehop as high as at least 20 other riders? I'm in no way saying that the big boys aren't impressive, I just disagree with the fact that anybody could ride like Danny but few could ride like Damon. -

Danny any time, I find Damon's riding quite boring. With Danny you never know what he's going to come up with and that's great -
Haha I was laughing like a twat throughout the whole video, it was so enjoyable Great riding Andrew, good choice of music as well - reminds me of when I was a kid Expecting your next video in late 2009.

Just played around with Premiere and modified a standard preset for you so it works properly. File>export>adobe media encoder Load this into the encoder (right click and save). This is how a compressed vid looks like. It's only 285KB/s with audio and @ 50fps and looks decent. If you really want to do it properly and have the time, visit this site. Well worth the read. Is it a long GU you have?

Click not going to be a quick download

It's impossible to lick your back. Now that's a fact Now who will disagree with that?

about 5,5 years not sure really trials only since late 2004

Basically I'm looking for a 31.8mm stem with a low rise between 10 and 15 degrees, something like a Hi-Fi low but about 150mm long. Hence my question, does something like this exist? I can imagine some XC stems might have this geometry if mounted upside down but I'm looking for something a bit stronger Also what's the widest 68mm shell isis bb you can get without spending a fortune?

Gó I'm going to adopt the å and call it alex. Really cool letter. å is similar to ą in pronunciation :]

Some time ago when I still rode mod, the worst 20" frame I ever had was a long GU, and the best - a 221ti which was really short. The GU was horrible, disgusting, bad and almost turned me gay. Now having ridden stock for half a year I find the long GU awesome. No idea what this means but maybe if you're going from stock, a long mod will feel more friendly?

Downloaded the music first and liked it so I got hold of the video. Very nice one but you seriously need to learn to compress movies. That could have been 3x smaller without any loss in quality. Audio gain was too high towards the end, at a guess you were using Premiere 7.0 or older? Those programs had severe sound issues... If I were to write a longer comment, it would be exactly the same as Rich's so I won't bother. Very good job.

Wow Seriously, use the search before asking a question

you can't format the system partition from windows just do this: put your windows cd into the cd drive restart the pc read what it says on the screen don't say you can't do it, just do it.

Nope, serious. I smell like a fresh toilet when riding and it's great.

I think 300 quid is going to get you a rather good camera. I'd personally go for a Sony MiniDV cam with an Advanced HAD CCD. The resolution of the CCD itself isn't that important unless you want to take pictures so don't go by definition when choosing. DV is always 720x576 pix. I've got a camera for sale but by the looks of things you're looking for something a lot cheaper. This is rather a good site with reviews Some images from my camera and another one I tested

If you've got a PR, every other frame will feel very different and be a big change. As somebody has already pointed out - despite the Monty geometry being very similar to any other short mod frame, the way these bikes behave is totally different. Might be because Tartybikes don't deal in Ko?
-
Apparently the geo is going to be 1085/60/375 with 110mm hub spacing.

Echo perfumed grips are great. They're very comfortable and have a nice feel, apart from that the rubber is perfumed. As useless as that may sound, it's a really good idea because it stops your hands from stinking after a few hours of riding in the heat.

Sorry for going offtopic but what's wrong with using loctite? The bb in my old frame kept coming undone, flooded it with Loctite 270 and after half a year fairly happily unscrewed it. Most bb's come with a thin layer of loctite substitute applied to the cups anyway. I guess a bb can bond itself to the frame when there's water in the threads?
