Skip-stopping on cottered cranks & Quandos!
Hey y'alls.
Just wondering if anyone's had bad luck skip-stopping or skidding with cottered cranks. Put together an old Fuji and I've noticed even after 1-2 miles I've gotta bang & tighten the (new) cotter pins. Wondering if they'll break if torqued into a full skid...
Well, everyone's had bad luck with Quando hubs, but has anyone increased their lifespan with high-test Loctite and/or just given'er when tightening the lockring? Heard about vice-tightening, but I'm afraid of stripping the threads (not that the won't anyway, sooner or later). Any sound advice and/or recommendations on stronger hubs (on the cheap) would be appreciated.
Thanks, buds.

I'd be kinda wary about the cotter pins coming loose...I don't really have any experience with these, though. I think that, when properly adjusted and set-up, they're okay, but it doesn't sound like these are. LBS...or just get new cranks.
Not going to get much cheaper than Formula hubs, and people like 'em. Wheelset's $150 on Nashbar.

I've sheered a cottered pin before. If at all possible, just get yourself a big-boy crankset and save yourself the hassle of having to tighten those things down every few weeks.

I agree. Another $20 for a Shimano sealed BB.

And a bottom bracket spindle, or a totally new bottom bracket. The spindle is an adventure -- there are 3 sizes of bb spindle for cottered cranks -- so getting a new cartridge is probably the way to go.

You might think about avoiding skidding until you have something more than a minimally rugged drivetrain. maybe put those brakes back on.
Try slowing down a bit until you've got $50 for a new BB and used cranks (or $25 for a used spindle/used cranks).
for the hub, using a duraace cog (or similar) so you've got a nice wide threaded contact area will help you avoid stripping as opposed to a thinner cog. I'd say the duraace cog I use now has 50% more contact area of the surly one I used to use.

yeah get a new set of cranks/BB; if youre have problems already it will only get worse (speaking from experience).

cotters suck balls. no two ways about it. get some real cranks or you'll be real cranky.
