^ you wouldn't catch a cat with that much filth on its snout.

slamm jeeeezus!

bejeeezus!!

this is the kind of thing that gives yellow bikes a bad name.

I had an intermitting clicking once and it turned out to be a crack in the front rim around one of the spoke holes. Doesn't really explain why you only get it when pedalling hard but it's just a thought..

^ brilliant.

The best i can manage is

i don't know what you might be referring to, but whatever it is, I probably wouldn't be typing at my laptop at the same time ;)

my cat's in my lap right now, but I can't reach the usb cable to get the photo off the camera. :)

mmm.. butter spokes. for a real smooooth ride.

while we're on the subject, does anyone have recommendations on spokes and nipples (and where to get them) for my first build? I've got front hub, rim, spoke length, and jobst brandt for a manual. Not in any hurry.

The Bicycle Hotel, of course.
It's quite nice, don't know if it's exactly super budget.

And then there's The Greenhouse - you can't sleep there but you can stare at the mirrorball for a couple of hours - it's quite mesmerising if you get into the right ..erm.. frame of mind.

^^ heh. they didn't say what kind of breaks it has.

ha! At least you had a slow speed fall.

Reminds me of what happened a few weeks after I first went fixed. I wasn't quite diligent enough in tucking my flappy trousers into my socks (so there is a point to tight hipster jeans after all...) I'd just turned into Voltaire Rd off Clapham high street when the trouser leg got caught. The back wheel locked up and I skidded to a stop, still upright, and realising there was no way out (clipped in!) I said to some passing guy, 'I'm going to fall over now'. And then did, in sort of slow motion comical, try-to-land-on-my-hip-rather-than-the-bike way. quite an effective way to learn that particular lesson i think..

that's terrible news. he'll be missed.
I bought my first track hub off him almost 10 years ago.
He's clearly had a huge impact on a lot of us and (I would imagine)
thousands of cyclists the world over, so that's quite a legacy.

SB, if you're reading this from your great celestial internet cafe,
I salute you sir!

that stem is an abomination.

I can't imagine what you'd have to attach it to for it not to look out of place.

dogsballs, doesn't that 111mm bb throw out your chainline?

it looks like the bike of a serial murderer.

chris crash dude my mom is a crack whore.

you mean a crank whore

Sugino 75 + Miche + Formula + Condor CNC = kowalski
Sugino 75 + Miche + Phil Wood + Phil Wood = adoubletap
Sugino 75 + Hatta R9400 + ShimanoHB7600 + EAI superstar cog = Tynan
Dura-Ace + Sugino 75 + Dura-Ace (7600) + Dura-Ace = hassanr
Sugino 75 + Sugino 75 + Phil Wood + EAI = mr_tom
Stronglight + Shimano UN73 110mm + SystemEx + EAI -2mm = mr_tom
Campag + Campag Centaur 111mm + Suzue Promax SB + EAI superstar = oddsock

did one of you guys get that dura ace 7610 bottom bracket that just finished?
I was after that! But i wasn't sure if it would fit sugino 75 cranks so I
didn't feel like bidding that much. Hope it makes you happy ;-P

what, you actually want a name instead of some vague recollection of having seen it?

Breaking Away.

^^^ great film that.
but his front quick release lever is all wrong.

It is to do with the center of gravity being high on bike that limits braking power of a bike. The friction which can be archived between the fount tyre and road is greater than or equal to the amount needed to allow rotation about a point (the point in question being the contact point of front wheel to the road surface). DUe to the longer nature of a tandems and cars (also the lower center of gravity) the amount of force required for the car / tandeml to pivot about the contact point it greater than the maximum friction that can be achieved.

Right. Having thought about it some more (not that I suppose anyone cares at this stage), I've come to the somewhat surprising conclusion that the height of your centre of gravity doesn't matter at all. What counts is the diameter of the front wheel and how far back your centre of gravity is. Your maximum deceleration as a fraction of g is (distance c.o.g. behinde axle)/(front wheel diameter). I have diagrams. Yes, I do have better things to do...

no... that's not right either. i was doing statics around the front axle but there's a net acceleration so we need to balance moments around the centre of mass. the right answer is maximum deceleration is
(distance behind axle)/(height above ground). which is more or less what we said in the first place. I'll go and do something else now.

Caspar These guys were masters of hitching lifts, they give a decent dash of realism to every day life too!

don't know about you but I always thought that The X-Men should have been a film about a bunch of post-op trangender individuals.

TheBrick(Tommy) [quote]chris crash some one said that we could stop at about 0.5g with a front break, and cars at 0.8g, so they would have roughly 60% more stopping power.

they would also have more mass, a lot more mass, greater then 60% more, so i at the same speed would have more velocity and therefore a longer stopping distance. i would also hazard a guess that the 0.8g is for all four wheels with the pedal break, while the 0.5 is for just a front.

It is to do with the center of gravity being high on bike that limits braking power of a bike. The friction which can be archived between the fount tyre and road is greater than or equal to the amount needed to allow rotation about a point (the point in question being the contact point of front wheel to the road surface). [/quote]
good point (pun not intended :) - it's the angle to the contact patch, not the axle, that matters.

chris, the extra mass of the car doesn't matter - a car at 0.5g stops in the same distance as a bike at 0.5g, so at 0.8g they've got a significant edge.

chris crash we should be able to because the stopping power is just less then double.

Where do you get that from? On a bike, maximum deceleration is determined by the angle between the centre of mass and the front axle. Once your deceleration reaches a certain fraction of g, you'll get a net moment the wrong way around the front wheel and over you go.

On a car, the centre of mass is lower and further back, so they can fit much stronger brakes without worrying about the thing flipping over forwards under braking. The limiting factors then are traction and the strength of the brakes themselves. Well, they have a more rubber on the road (though I don't know if that makes as much difference as you might think - it's probably more to do with the texture of the rubber) and you can bet the calipers on car disc brake can squeeze a lot harder than you can with your little lever!

Rather nice little red cannondale, black forks, risers, phil hubs, parked outside Brixton Tesco just now.
Think I spotted the owner inside but couldn't be sure and anyway, I had a hot apple crumble to get back to at home :)

There was another SS parked out there as well but it had me bit puzzled - it was a Specialised Specialized cross frame by all appearances, chunky tyres, cantilever brakes and wide clearances, but with track ends. Didn't look like it was built that way but then again didn't look like a conversion.
