Re: [RBW] Broken Crank (Quickbeam)
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.

The torque is going to gradually relax, and stresses become really high on the inside corner - the one that's loaded when you step on the crank. I had the same thing happen on a used TA5 - broke when I was taking off from a stoplight. http://img.photobucket.com/albums/v728/bulldog1935/Raleigh/700c/aP1207649.jpg http://img.photobucket.com/albums/v728/bulldog1935/Raleigh/700c/aP1207650.jpg -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

Jay, it's only Lambert foils from Cyclomondo. It was an Anglophile splash, disavowing the French connection. http://img.photobucket.com/albums/v728/bulldog1935/Raleigh/700c/aPA110001.jpg On Thursday, April 30, 2015 at 8:34:30 AM UTC-5, jay hartman wrote: Not to be pedantic, but that looks like the Lambert copy of the TA crank.

In that case, my apologies. Nice bit of camouflage too. Jay On Thursday, April 30, 2015, Ron Mc bulldog...@gmail.com wrote: Jay, it's only Lambert foils from Cyclomondo.

[RBW] Broken Crank (Quickbeam)
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://www.statrix.com/2015/04/2015_jbk_ride_report/) Anyway, I left work today, hopped on my bike and was going to run a few errands and maybe put in an extra mile or two (and I do mean just a mile or two - but still fun, eh?) I was at a light and when stood and pushed off when the light turned green my foot sort of kept going to the ground. Luckily I didn't fall and stopped, though it probably looked clumsy. I couldn't figure out how I'd missed the pedal. I hadn't. My Sugino XD2-QB double 40/32 175mm and come undone. https://www.flickr.com/photos/mgps-bob/sets/72157652254822642/ I didn't take an image in place. I got the hell off the road. :-) I bought the bike in December 2009 and have ridden the heck out of it. I've also mostly been a lot heavier than I am today (also documented in other emails around here). I've gone from 275 to 197, mostly since November 2014. If you do the math, the crank mostly got me at my heaviest. If you look at the break it seems pretty clear it'd been a while coming. There are definite differences from one side of the break to the other. As I said, I'm really just grateful that it didn't happen on the century this weekend, or in heaving traffic (could have too). It was pretty much a non-event. For those who wonder, I have a Hunq that'll be ridden a bit more now. If I'm annoyed with anything it's that I just, and I mean just, ordered some new cork grips from Riv and now will have to order a new crank - twice the shipping charge. If I'd have waited a day or two on the cork grips it could all be one box. Sigh. Luxury problem. Anyway I ride the bike almost exclusively in 42x16 mode and figure I'll get new chainrings and a new single speed cassette - all contingent on taking the chain off and actually seeing what things look like - I might be okay. As for the Hunq I just had a new dynohub wheel made for it and when I got home instead of playing around the with disassembly the QB I put on the new Eyc light, Top Line rear light, and wired it all up. Tomorrow I have a late ride 'date' and until now only the QB had that much light going for it. :-) Aloha, Bob -- Robert Harrison Honolulu, HI rfharri...@gmail.com statrix.com Wu Name: Tha Eurythmic King of Nowhere -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.
