Stopped by a pebble.



A delicious moment from a ride tonight. Guy on a 35 year Raleigh, and another on a CF wonder bike.

I broke a steel crank pushing off at a stop light. It was also 35 years old.

Don't leave us hanging - how did a pebble cause the mechanical? Or are we talking about a flat?

So who has the mechanical?
hey, that is a 41 year old Raleigh, so that changes everything...

If it matters, it wasn't me that found the pebble... the CF rider found it himself... it was really jammed up in the sidepull brake and dragging on the tire.

Steve in Peoria, and totally unaware of being photographed.

Is the joke that cf bikes don't have issues mid-ride?
I'm like that kid in school wanting to laugh at someone during lunch since others are, but unsure why I would laugh.

No flat, the pebble wedged between the bottom of the front brake caliper and the tire and slowed him down to a crawl.

No clearance, even with small tires.

I guess that's how they make 'em nowadays.

Edit: Since it's pretty easy to pick up tiny stones on your tires, it makes me wonder how guys who race these things deal with this.

When I used to run 38mm tires on my 1988 Trek 400 I'd get stones jammed up in there all the time. They'd only stay there for a few seconds, usually.

CF bro probably had too much pressure in his front tire. Drop it down a couple of PSI and it probably woulda popped back out.

In addition to messaging with work and my wife while riding, I sneak in a lot of pics, too. ;-)

Steel bikes were the first to have the crazy clearances. Not that they survived the test of time either.

My 2001 crabon road fork with dual pivot 105 brakes fits 32mm knobbies. Not too shabby.

What ever happened to using tire wipers?

I think Jobst Brandt is wrong about them, and I think Sheldon is right in this case:

That article is talking about reaching down and wiping the tire by hand, not about the mechanism.

I dunno, this thing had just a tiny, tiny sliver of space. I have never seen such little clearance, although I don't pay attention to a lot of the new fangled racing bikes out there.

Now that I think about it, maybe the brake is supposed to act as a tire wiper.

My Eros used to do that a lot! It would make this little "kk-kkhk-kkh-khkk-Thoom!" sound from time to time and I couldn't figure out the cause at first. Turned out that the tire clearance to the fork and front caliper was just right to allow little stones to get picked up and grind before getting ejected. Using a file and Dremel to gain some clearance and adopting moderate pressures seems to have helped.

Good thing those little stones never completely jammed the tire!

Yes, because vintage bikes never have issues.

The winner of the Tour de France this year had a pebble lock his wheel up during one of the final stages. He dealt with it just like the guy in your photo, except he did it on live TV.
