Any question answered...

Could I grab that tonight Tom?

Got a chap coming over to test ride the bike, would be good to know if I can possibly make it a better fit for me before commiting to selling it.

I'm supposed to be out pizzaing I think, can nip up and stick it under the volvo or something this afternoon though?

That would be awesome- it should fit through the letterbox, I'll PM my address.

Say hello to James and Higgs whilst you are there.

^^ try not to drop a stem on them as they trot up to the other side of the door in a welcoming fashion

Please can someone recommend me a nice pair of risers that don't cost the earth? Not sure if am gonna go down the OS or 25.4 route, may have a stem for OS...

Preferably lightweight and black.

I have a pair of white ones that you can have, free and gratis, 31.8mm clamp though?

That would be spot on, unless they're cut to hipster width? a mates got a 31.8 stem for me just need to pick it up.

Uncut, boxed, unused.

These ones: http://www.planet-x-bikes.co.uk/i/q/HBFSMAXIMUS-WHT-MTB-318/fsa_maximus_riser_mtb_handlebar___white___mtb___318_mm_clamp

Do you still want those BB7's btw?

That would be awesome- it should fit through the letterbox.

Your Volvo has a letterbox?

Is there any online video of the Team GB team pursuit today? I want to watch them smashing the world record like bosses.

Right, bars sorted thanks to Dammit, can anyone recommend me so long, supercomfy grips? Preferably con flangé, and maybe dual compound?

Should I just get ODI longnecks or is there something better?

i actually have found that my charge ones are pretty comfortable, better than the genetic ones i used to buy

Their soyo type ones? After something thicker/squishier than themz.

Also if I'm tight on clearance and I go up a tooth on the rear will it take me over the edge? Or is the difference fractional?

Technically, the difference is the result of a complicated formula involving lots of fractions with large denominators, but as a first approximation the fraction you're interested in is ⅛, which is the distance the axle moves for each 1 tooth change in either sprocket or chainring in a fixed gear drivetrain with a chain pitch of ½, assuming no change in total chain length.[/quote]

So does that mean on a 3/32 cog it will be 1/2 of 3/32 of an inch?

ie 0.046875" or 1.190625mm?

How much did I drink last night that I ended up with indigestion so bad that a packet of Rennie hasn't touched it?

How stupid are some people?

If you think about how stupid the average person is, well half of them are stupider than that.

I found these to be very comfortable

Ha, was just posting these!

I prefer the OG flanged, but whatever floats your boat.

Maths fail.

The stupider the stupid people are, the fewer of them we need to achieve the same average.

Ive never been a fan of flanges (hurr hurr)

What's the quietest time at look mum on a thursday? Quiet but open.

Is it possible to get a 26.4 crown race onto a 27.0 crown?

I have tried, and it seems evenly seated. But there is a hairs breadth of gap all the way around. Ok to ride?

No, width has nothing to do with it. It just happens that a pair of sprockets connected by a chain will have their axial separation distance changed by ¼ of a chain pitch for each extra tooth added to the total. This is because the circumference of the sprocket increases by a whole chain pitch, but only ½ the sprocket is taking up chain, and the extra chain taken up is divided ½ and ½ between the upper and lower straight runs. It's not exactly that unless both sprockets are the same size, as other arrangements have more than 180° of chain wrap on the larger sprocket (and less on the smaller) and the straight chain runs are not parallel with the line connecting the two sprocket axes, but for the normal range of bicycle gearing and chainstay length, it's close enough. If your change makes the difference between chainring and sprocket smaller, the hub axle movement will be slightly back from the approximation, and vice versa, e.g. going from 48/18 to 48/19 will move the hub axle forward a bit less than ⅛", whereas going from 48/18 to 49/18 will move the hub axle forward a bit more than ⅛". The error in these cases is of the order of 0.02". This is irrelevant for clearance purposes, but handy for dialling in magic gears.
