Best thing to do in my opinion is get yourselves onto Gabbys webshop and buy some TRP cantis instead  |
Or go and get some Frog legs cantis from paul milnes for about 1/3 of the price work just as well if not better

let's not forget that this only really influences the top end guys, they're the ones who'll have to think about it - does the improvement in stopping power in a few situations warant the extra weight.
The rest of us in the midfields of the fish and chippers will be battling each other on 'cross bikes and mtb's anyway. whether the chap next to me has disk brakes on is not my major issue, whether they can go faster than me, is!

in my limited experience of cantis, they stop you a hell of a lot slower and less predictably than an avid BB7 cable disc brake. discs rock. as for safety, you might as well moan that you could get poked in the eye by the cable end of a canti brake - frankly i can't think of any cross race i've seen where you would have to brake enough to get the things hot and who the hell is using sharp discs? has oddjob started making bike bits now?
I'm not likely to ever enter a cross race though so my opinion is kind of irrelevant.

IIRC correctly you have a pretty tidy setup for commuting. Can you post a pic up 'ere as I was thinking of doing something similar. |

I nearly cut my index finger off the other week on me mates chainring when I was taking a bottle cage off for him, the teeth were that sharp. Surely in this day and age you would have though someone could have come up with something safer than a row of sharpened spikes to drive a chain round. I am incensed that we are allowed to actually race with them. And while were on the subject didn't someone almost bleed to death in the Tour of Ireland when a bladed spoke severed an artery or something a couple of years ago? Bikes are bloody lethal if you ask me.

i'm about to order one, not got it yet - it's going to be one of these:
http://www.orbea.com/en/bicis/modelos/diem_drop/presentacion/
on my fixed bike i've just ordered a pair of kinesis dc19 disc forks, hope pro II on cxp30 and an avid BB7 road to convert it to disc front end, it'll be mega. (obviously i don't really need a back brake so i'll keep the caliper on the back)

On a related note, do all disc brakes squeal in the wet? My mtb brakes make a right racket when wet, the seller said that there's nothing to be done, design fault.

Few things, stopping in cross = pointless, i can't off hand think of any instances where i've wished to be able to slow down quicker. Not to say it doesn't happen, but infrequently enough to not be an issue. On the flip side, i regularly wish i could slow down more on my disc equipped MTB. Tyres are the limiting factor, and will remain so, physics isn't going to change. All discs are sharp its a function of them wearing. And light weight = small discs = higher temp. I'd expect crossers to need no more than a 140 on both ends.
Jonno, all the other bits (cables, chainrings, spokes) are either stationary relative to the frame, on a freewheel (so easy to stop) or a long way from the centre of rotation (spokes) so don't have a significant risk of chopping owt off. Discs are none of the about. If you touch a disc on a bike that is being carried and the wheels are rotating (fairly usual practice) it will more than likely slice you, even if the wheel is only going round at 5 mph. Hit a spoke, the wheel will stop.
And its the midfield where its going to be worst, its where the experience is limited, the racing is closer and people make stupid mistakes. Like sprinting for 40th. |

My current fixed bike (not done the disc conversion yet) same frame as the pearson touche but it looked a bit bare so i bunged some random stickers on it.

hi
probably going to regret putting this on here, but here goes
why is there now a ban on tyres with 35mm
I am now classing myself as a "not many"

"since not many run on now banned 35mm tyres" |

not all tyres marked 35mm are actually 35mm wide
I have some Vittoria tubs that are marked 32mm but if you meas.ure them they are 29.8 mm.
Do they intended to have a guy with a caliper at all the races measuring everyones tyres. ??????? |

Apparently, yes.
Don't think that will be anything but UCI races. |
