![]() Not all chromoly was 4130, and even among 4130 there is a lot of variation in quality. "are these 4130 chromoly? Well, kid they're "cro-mo".which is the same" no, it wasn't. The late 80's/early 90's brands brought out a lot of bullshit marketing terms to sidestep the fact their parts were made of the cheapest metal they could find. (Now whether that means anything, who knows, it's very possible those cranks were made out of the same metal they made Go-Bots out of. The brands I bought were GT Power Series 1 piece and Odyssey Excalibur, which as far as I know for the time period (early 90's) were the highest quality. It got so bad that cranks that weren't bent felt weird to me. I bent a LOT of pairs of one-piece cranks back in the day, mostly from landings to flat (stair gaps, ledges, and launch ramps). I'm at least 20-25 pounds heavier than that now even at my most lean. When I was a teenager I weighed around 145-155 pounds. Schwinn Diamonds were rigid and very difficult to bend. I think they were ideal for riders up to.perhaps 180lb. The thing that makes the most sense would be that Takagi was thinner and harder than Sugino.īut should someone who's 240 lbs trust them? For jumps and shit? Probably not. I used to bend Sugino, which felt more rigid in regular riding. Which was fine by me, because mine always sprung back. Feel free to mention two-piece cranks!īack when I weighed 180lbs, I could bounce on Takagi without even bunny hopping the bike. Please, don't mention bent cranks and regard some generic steel entry-level set. Also, what's the deal with tubular? Could it be a salvagable design concept? I heard they are scary, but I've not had the opportunity to snap a set yet. From SR TurboXs, to Takagi Grandes, Schwinn Diamonds, and Ashtabulas, I would like to read up on your experiences and determine if strong and light could be produced for cheaper and constructed simpler (less labor-intensive overall). I made this forum to discuss the absolute best one-piece cranks designs. In theory, they should be able to achieve comparable strength to three-piece cranks, but reduce machining costs by a big amount. So, after doing some reading, there are still people who swear by one-piece cranks.
