Dunno if those cranks Primo style have floating axle/bb setup, but i've been running a set of FSA Xdrive cranks and BB (3 piece setup exactly the same as Profile but way cheaper) for about 2 years now on 4 different bikes, 3 of them trials. They've fit every bike i've set em up on with no problem. 3 piece cranks with floating axle and spacers equals never a bb size or clearance problem. Still wouldn't mind the ti axle with Profile race arms for a bit lighter but bah.. they'll never break.
oh yeah.. chainlines are cake with em. This thread was about some other crank wasn't it?
i'll shutup and go to sleep now. Fucking 4 am rants.. :eek3:
Those cranks and the company that makes em look promising. I like the idea of aluminum 3 piece style. Wish they had Profile splined bb and not Primo square thing. Small rider-owned company that owns their CNC mill that's open to custom stuff and making parts for cheap in the US? Sounds good to me. I love run-on sentences. :joshers:
I know a few people who use the cranks, they seem to work flawlessly so far. I support Phat Moose and any parts they sell. Phat Moose has given so much to the trials community in Ottawa. Andy T, don't talk shit, no one said the cranks were designed for an xtp, or even trials for that matter.
I've got a friend that owns a CNC mill...it's in his garage. 4d machining, the whole 9 yards. Costs $50 an hour worth of electricity just to have it on, LOL! For those of you that are like..."a CNC mill in his Garage? BS!" Yeah...in his fuckin garage. He had to get his garage wired for 440 volt outlets, etc.....the rep had to go out there just to get the machine set-up...pretty insane. Costs a pretty fuckin penny too.
He made me and a couple buds a pullstart handle for our Mini Choppers and pocketbikes.....pretty pimp IMO. I would get brake boosters and cranks and all that stuff made, as those are REALLY easy to machine...but eh.....why? Just so I can have some generic cranks? A stem would seem like a logical little piece, but a stem is WAY more expensive to make in terms of machining time...but that to is kinda bobo... Ooooh, I can have my name engraved on the side, LOL! But eh, I guess ALuminum is Aluminum, so it wouldn't make a difference.....
Damn tanner...industrial. :eek3: All he has other than that mill is the CNC lathe....
You probably COULD make a killing off of them, depending on machine time (threading, and actual machine time from metal thickness and just plain out complexity)....CADing them up would prolly be the hardest part...by the looks of what would be needed, you could prolly cut an ASSTON out of one 15"x15" piece of billet if you laid them right...
Yeah...I hear ya...his CNC mills are HUGE....like the size of a shed in your backyard, LOL. Seriously.....that thing just SUCKS electricity. Considering you can use a 3/4 chuck on a booster....you could prolly churn them out pretty quickly.
And Considering the Adaptors for 4-bolt-> V-brake are nothing intricate...a 3/4 chuck should slide right through the AL....you could prolly make 10 sets in an hour....optimisticly, $50 of an hours worth of electricity...you can pretty much go from there for your profits, LOL!
