Re: Theory behind unintended unclipping from Eggbeaters?



The Crank Bros. website used to humorously describe their triple Ti
pedals as "fiscally irresponsible". It's foolish to purchase any of
their Ti models since thay have no advantage over the all stainless
model and they still have the less than stellar inboard bushings.
Regular eggbeaters are already lighter that most pedals except for the
likes of Speedplays, M2, etc. The small decrease in weight isn't worth
it. You could make up the difference with minimalistic road shoes if
one is set on being an ultra weight weenie. Maybe compromize by
shoe-gooing some lugs onto a set of high zoot Carnacs :) Anybody
considering blowing their money on the titanium models would be better
served by investing in the superior bearings of the Quattros or Look
4x4s instead.

I wonder what the durability is like with the titanium bodies
considering that the design depends on softer sacrifical cleats to
mitigate grinding against the retention mechanism. Older Time ATACs
that used spring steel for the retention bars had a reputation for
wearing down the pedals. I would be concerned about the same happening
with the Ti eggbeaters.

Regarding the unintended clipouts. This can be exacerbated by people
who have too much foot pronation such that they are always riding at
the limit of the float or who let their foot flop around enough to
release the cleat. The release angle decreases over time because of
cleat wear so these riders may only start experiencing problems after
putting some mileage into their cleats. Eggbeaters have very little
resistance when clipping out and they don't "suck" your foot into
alignment like SPDs so riders transitioning from such pedals may have
bad habits that don't work well on the eggbeaters. My most heavily used
pedals (7000 miles) have developed play in the wing to body interface
but I haven't experienced any unintended releases so far. They would
have to develop a lot more slop before the bars were wide enough to
pull out of (aside from use with a heavily worn cleat). I wonder if the
people complaining about pulling out with new cleats have bent the bars
after bashing them on a rock.
