Greetings

Everything black + red hubs. Please don't buy all the parts in red, these colours look so gay. It's a bike not an art gallery.

1 - 4 times more expensive = 4 times better Just get 4 cheap hats and wear them all at once.

Or in other words Bicycle disc brakes where at first used only on downhill rigs. As you can imagine, when you brake for a long period of time, the disc gets very hot, so do the pads. The heat is transferred into the system which warms up the fluid. This then makes the fluid expand, and without a resevoir it could lead to the brake locking itself up, which you wouldn't want to happen when riding over 30mph down a hill. With a resevoir, all the "additional" fluid, just flows into it, keeping the brake safe and this is what is refered to as an open system. It's not something you'd need in trials, actually I think a closed system is much better for this sport. But as there is no trials-specific brake (the Hope Trials uses the same lever which is mounted on every other Hope brake), they couldn't be bothered to make a closed system which would have very limited use. As for the resevoir itself, there should be no air between the membrane and where the fluid is, and no fluid above the membrane. There is normally a small hole in the resevoir cap which allows the air to be released from above the membrane when the fluid expands. Maguras don't have a resevoir because braking doesn't generate any heat = the fluid doesn't expand.

Eh? Bet you don't know Swedish as well as he knows English? Back to topic, I thought Mavic made such hubs.

Can we have a larger pic like 1600x1200? That is just incredible

Yeah, beautiful is the best word. I'm speechless

Get an IRC ElGato, got mine off a mate with hardly no thread on it and it grips like mad Snakebite-proof and very light (800g).

Too long but good. You've got a nice style

Bloody hell, that small guy is good Nice video, didn't like the music though. It reminds me of LCD screens for some reason.

As above, just wet the rim and ride around with your brake on. Then wash away the dirt Repeat a few times for best results.

It's a repost, good movie though. Freeride is a bit poor I think.

That's really impressive. Despite what you write about buying trials parts being a problem, you've got two proper trials bikes there! Liking the first one a lot.

Very nice, I want to ride it!

It's a bit like what you advised me to do with my frame. Do the same thing

PM me if you want mine. I don't need it.

Indeed, what else would you expect from an 8" rotor on a 20" wheel

Do you have to vomit onto every good rider on this forum?

As it was said before, the Ti hub is the only hub which will fit the PR frame without having to bend it. Running a wider hub will end up with the chainstays cracking after a longer period of time. I think that Profile have got their disc spacing wrong, the same applies to BMX King hubs fitted with an ISO Disc hubshell. So you can either get a freehub and risk cracking the frame, or buy a front freewheel. Go for a freehub.

Yay! Really really really good video. The editing was spot on, interesting camera angles, music was also great That guy on the red Ashton is incredible, has so much power yet keeps things effortless and smooth.

I'll be getting one on Monday, asked the tarts about them and they say it's basically a Try-All freewheel but with less pawls. Not sealed, hasn't got a cartridge bearing like the ENO.

Pads: Coustsinks Time used: 2 months? Rim used: Zhi 26" Front/rear?: Rear Grind: Medium Brake used: Magura HS33 2005 & 2004, water bleed, integrated booster What is your opinion of a working brake: Powerful in dry and wet weather conditions. Hard feel on the lever. Similar products tried: ZOO!, Plazmatic, RimJam green, Monty Pine pads. How do they compare to previous pads you have used: Best pads ever but at a steep price. Well worth it though. Review: To my surprise, they don't "click into" the cylinders. You need to mount the brake and press the lever hard for the pads to lock properly. Dry weather: Very powerful on a grind and smooth rim, with or without tar. The pads need bedding in with water every now and then because the dust from the rim and surroundings reduces the braking power significantly. That is however a common problem. Wet weather: If you have a tar-free and clean rim, these pads will stop you regardless how wet your rim is. They don't brake well on a smooth wet rim so you will need a grind. I was recently riding in the rain and there was no drop in performance. The brake was locking equally well, I didn't realize my rim was wet until I touched it. I find you get the best performance in damp weather (ie. in a fog). Extremely loud brakes, wear resistant, CNC backings make it feel very nice indeed. These pads are by far the best I've ever used, they haven't slipped a SINGLE time when set up correctly (clean rim and pads). And get the CNC backings, it's well worth it. A refill costs 15 quid which is about the average price for a set of brake pads yet you get the unmatched performance of the Coustellier compound.

It's 3mm thick steel, can't tell you exactly what it's called because i don't know the name in English (acid resistant steel? ). I wanted to buy aluminium but it was unavailable at the scrap yard I went to. The adaptor cost me about 10p to make/get the materials. Weighs 176 grams but you can easily remove some material without making it any weaker. Haven't got the geometry of it as it's not accurate and I bet it would need redesigning if used with a different disc brake (ie. a IS mount, this was designed for a post mount with adaptor mounted the other way round). I think Wally's 1st adaptor was CNC made (at least it looks like it was). The pictured one is his 2nd attempt. I think it's VERY strong. The forces working on such a shape are really small, even if it's a disc mount. I'd trust this much more than a factory disc mount on a frame. The ZOO one I made was twice as thin yet still lasted me 2 months without any problems, then I just sold the frame and didn't need it any more.

Just make one yourself. It will last if made properly. Wally's old Python: My old Python: My old GU: Piece of cake. edit: Can't find my Python adaptor, it looks fairly similar to this one which was made to fit the GU.

Answered it yourself.

Get the disc wet and ride around braking. Water polishes the disc and gets it smooth. There were thousands of topics like this here and in NMC, it doesn't really matter if it's a BB7 or something else... edit: didn't realize the date It won't bend the disc because it's thin, it's like pouring boiling water into a thick glass - it'll break because the inside of the glass will expand quickly yet the outside will remain cool. With a thin glass the heat penetrates it straight away so it expands evenly. Glass isn't flexible, a disc is - that's why it would bend and not break. Still, we're talking about such small figures here that I don't think something like that could happen.
