So BE CAREFUL around corners and curbs! - A pedal strike can land you in traffic - never mind a bent crank!

(Lovely SC, by the way)
I've been riding bicycles for hundreds of years (ok, more like 44), and I struggle to think of how one could strike a pedal hard enough to do that without crashing. Pedal strikes are rare - especially amongst folks coordinated enough to stay upright after something like that.

I'd try what robbietunes suggests. Reduce - reuse - recycle... no point shrinking the supply if you don't have to.

Easy. Pedal bites into the pavement, forward motion carries it on through the downstroke, lifting the rear wheel off the ground. Presto, there goes all pertinent traction on your rear wheel.

Came pretty close to doing that once when I was green with roadbikes, and had a set of similar wide pedals on the '84 Raleigh Competition. Went through a left-hand corner hard and fast, with the left pedal down. Forgot to bring it up. Scraped like hell, and for a half-second, the rear wheel lifted. I was already putting pressure on the right pedal (split-second reaction to the left pedal's position - not a reaction to the pedal strike), hence, the left pedal lifted quick enough that the rear wheel came back down at an angle still shallow enough to recover from. Made it through the turn without incident.

That, my friends, is why I no longer use anything wider than a Campag Record road pedal (and on everything else, use MKS Sylvan track pedals). It was also the last time that Competition went out with those ungainly rat traps.

I sold a bike recently, and 60' into her first ride, pedal strike bent the rear reflector off her 105 pedals. Happens a lot, but can high-side you in a heartbeat.

The idea with the machine shop straightening the crank is they have the mounting equipment, and be sure to tell them the direction of force that bent the arm. Correction has to be in the exact opposite direction, and you should be fine.

Plus, those guys love to do stuff like that.

When in doubt stop pedaling, and put the pedal opposite of the turn down. I think I was about 8-10 years old the last time I got a pedal strike?,,,,BD

[QUOTE=old's'cool;11092039]I had a pedal strike on the (basically vacant) MUP on the way home last week. Knocked me way off my cornering line so that I left the path and reacquired it on the apron of the bridge that came immediatley after the corner I was taking. That was a nice abrupt 2" upward step back onto concrete from the field; the apron ended with the end of the bridge and I was back in the rough again; I somehow managed to manoeuver back onto the path without wiping out. /QUOTE]

A bit reminiscent of this, perhaps?

Thanks for the tips RobbieTunes.

It happen pretty much how Cuddak888 described his experience, only my pedal dug in and altered my course by about 45 deg. The rear wheel now has a significant wobble that needs to be corrected as well. I think my teen years in BMX paid off in keeping it all upright.

A friend has a recommendation for a machine shop that should be able to do the work. I'll give them a try this week and report back. With big pics!

I was looking through my collection of Campagnolo Record pedals, and the are all beat up in the area where pedal strike happens. I think I have 3 sets, and there isn't a pristine dust cap or cage in the bunch.

Never bent a crank arm that way though

Sounds like an ill-timed pedal strike effectively ended Lance Armstrong's long career today. He banged a pedal and crashed in a roundabout just a few kilometers before a crucial climb in the Alp stages of the Tour de France. He fought his way back to the pack, but spent so much energy catching up that he cracked on the climb itself, finishing the stage a hopeless 11:45 minutes back from the leaders. Watch those pedals, whether you are riding C&V or at the highest level of racing!
