Re: [RBW] Re: Broken Crank (Quickbeam)

I ran a Campy square taper crank with one 39t ring on the outer side of the crank with single ring bolts for a long time. The Campy 110 BB set up a perfect chainline. Recently switched to the VO with 44t ring and 115 BB which is a little inward. Michael -- You received this message because

Re: [RBW] Re: Broken Crank (Quickbeam)

I don't have access to the bike (rode my Hunq to work) so I can't take a look till tonight. I do not remember it being near a stamping, but I also don't remember what I had for lunch yesterday. :-) I'll check tonight. Bob On Thu, Apr 30, 2015 at 6:41 AM, Ron Mc wrote: > BUT > > >

Re: [RBW] Re: Broken Crank (Quickbeam)

As far as I know it's never been dropped onto the pedals. And as far as I recall, the only time I've ever fallen over on that bike it was on the left side, not the right, and it was (embarrassingly) while I was stopped and tried to turn to talk with someone and got tangled and, well, never mind. :-

Does anyone make quality steel cranks? Seems like a perfect "Riv" project. On Sat, Feb 14, 2015 at 1:34 PM, Benedikt wrote: > I added a few pictures for those of you who wanted to see the other side of > the crank including some "mating" the two up. > https://www.flickr.com/photos/neutralbuoyanc
