I weigh 230lb and I used to be able to squat 600lbs although I've never broken any crankarms in the past. Since I'm a newbie to single speeding any advice would be appreciated.
Cycling has got me down to 220 from 245, while I can no longer break a 500lb squat, I have had a great deal of success with the ENO cranks. For a big, strong, buff fella like yourself you will probably find the square taper lasts you longer as well. I did in 0 xt squares and 2 ISIS GigaPipes this season. In fact the ENO cranks may very well be the only crankset I install in 2006.
Go ENO now before Ernesto makes you.
He might very well try...and after him there will be others. That said I seen the real and live Nesto from WI on sale...of course if you bought him, he wouldn't be able to bother you...
NESTO GOING CHEAP CHEEP!
BTW single speed will be much more up your alley if you experienced the same component and parts carnage as I did. consider full rigid too.
