Not to be pedantic, but that looks like the Lambert copy of the TA crank. They were designed for their proprietary spindle that was taperless. If you were using it on another bottom bracket, it's not surprising that it broke. A lot of people get the two cranks confused because they look so

First let me say...no injuries, no accident, didn't even fall over. Having said that, it was a bit unexpected and I'm terribly grateful it didn't happen this weekend when I rode the 2015 JBK Haleiwa Metric Century on my Quickbeam (and had a great time as documented in another email and at:

Well, that’s good news (that it’s an anomaly). I would think they’d want to examine the broken crank just in case this is the front end of more such failures, however. Anyone using one of these cranks should be inspecting them closely When you think about it, the stress on that end of the

The start of the break does look like it's along a machining line. In fact, it almost follow's it perfectly however there is no step up there. There is a step up on the crank just before it but the site of the fracture is a smooth curved transition up to the spider with a little machining. I
