i guess it depends on the tolerances between different manufacturers/factories

yeah primo make wheelchair tyres as well
Also i would like to add that i thought Primo is pretty big.
I THINK have seen belts for idk what kind of motors, with the Pr1mo logo, super thin 20" racing comets and other racing tires... Seems like they are in a lot more than 'Just' bmx.
yeah they were 500 quid in the uk (for the ox plat ones), but there were quite a lot going around at one point, and plenty of old slightly thrashed ones for like 50 quid.im a bit bummed tbh, been trying to pick up an old STA on the cheap for a while now (its a lot harder in australia than in the US), but now theyre gonna be priced well beyond what i wanna pay
STAs were north of 1k here from memory. Good luck finding one and even more luck finding one cheap in Australia. Keep an eye out for one in the States and then use myus to ship it over. they come up pretty often and aren't pricey.
It looks like the only thing is shares with any previous primo cranks is the basic arm profile, id say they were designed to be 2pc...?
Possibly resolved the pedal inserts.
Splined axle, so that should reduce the creaking.
The clamp area on the arm is now a more regular thickness, ie no axle corners on the top/bottom - http://www.albes.com/ProductImages/crankphotos/primopowbite.jpg so that should stop the breakages that occurred there across there.
Half as many interfaces to worry about.
this. they fold over real easilyeither they wobble all the time or theyre so tight you have to cut them off.
What? Just...no.Which is great if you have to take them off the first time you install them. Miss a couple of grinds and those threads are fucked. Its hard enough to get the flushmount bolt washers out after a few missed grinds.
Older Profile cranks had threaded arms so you could use an actual crank extractor to get them off. They seem to have removed this feature now though.
I don't think anyone bought them to tell you how it went. Ask seth kimbrough
Lol hahah. He's still our reli-rock hero though!
i nearly threw up when i saw these. 2 piece powerbites? arreeeeeuuuurrrrrghhhhhhhh fuck you primo
......
these new ones are disgusting though, another colossal primo fail
I don't really see where you're coming from. But i respect your point of view nonetheless.
It's just, they look 99,9% like the old powerbites, which imho weren't badly designed or shaped. You just need to like alloy cranks.
So to me, saying those look disgusting is saying any power/hollowbite looks disgusting.
That's opinion. But what is so fail about it?
I don't see how there's anything wrong with 2-piece since everybody and their dog are producing 2 piece cranks.
The 2 piece design allows for these nice big hollow axles, and without these axles your cranks are nót going to sell these days.
Basically it's reduced in weight, while maintaining strength, plus they've updated the crankarm connecting interface to something that is going to outperform the previous design.
Doesn't sound bad to me.
Your maintenance rules are right on, if you have 'old school' power/hollowbites; not a bad thing to say about it.
But the industry moved on to bigger and better things, Primo adjusted their design to the specs of todays consumers, and kept it looking like the same stuff.
If you ask me, apart from knowing how the inserts perfom, i'd say Primo did a good job on 'keeping up' 3 years late.
JUST like with their first female cassette.
That's a whole other story though, not smart but regardless, i still like to think Primo is a good company heh heh.
