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 similar.

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: http://w

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 cra

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 ex

In my experience, VO is very good about standing behind their products. When my VO bottle cage broke, they sent a new one. When a Nitto cage (bought from someone else) broke, I was out of luck. Eric N www.CampyOnly.com Twitter @CampyOnlyGuy Blog: CampyOnlyGuy.blogspot.com > On Feb 12, 2015, at

All cranks do have a lifespan, but it's usually in the 100s of thousands of miles. It depends on the rider – some riders are harder of drivetrains than others, but it also depends on the cranks. Material choice, the way they are made (net shape forging

I agree that alloy parts have a finite lifespan, but 13,000 miles for a crank arm seems a little short to me. I would definitely contact VO for a replacement--I've had very good experiences with them in this regard. Eric N www.CampyOnly.com Twitter @CampyOnlyGuy Blog: CampyOnlyGuy.blogspot.com
