Q: regarding straight pull hubs
Tom, I think you are confusing straight-pull (as in spokes without elbows, like nails) with radial lacing (where the spokes point towards the axle enter and don't cross each other).

I think maybe you ran afoul of his zealous opposition to factual errors more than you fully understand. It had mostly to do with his treatment of newbie riders on his rides. You don't have a bunch of new guys trying to keep up with you on a long fast downhill and then turn onto a dirt track without slowing and without warning them. The first time he did that I told him that wasn't very bright. The second time we were descending I told the others to watch for that. I suppose he didn't like that. |

Most of the Campy wheels have straight pull spokes and radial lacing front and rear. Though going out and looking at them none of them appear to be disk. But how the hell could that be? Everyone is using disks now aren't they? |

The more things change... Interested in building a pair of rim brake Powertap Enve wheels into a disc brake wheelset but not sure if the original evenly spaced rim is appropriate for a hub designed for straight pull spokes (different spoke crossing layout/drilling, perhaps?). I want to use this powertap hub: https://powermetercity.com/product/p...rear-disc-hub/ TIA Sconnie Straight pull hubs and standard rim drillings are common. The Easton Vault hub is an example. https://tinyurl.com/scshrsa I don't think the Powertap would be any different. Some builders mix up the lacing so it's non-mirror image to resist disc braking forces, but I don't. I build discs the same way as I build any other wheel. I don't see any reason why you can't use your existing Enve rim -- assuming the correct number of spoke holes for the rim. -- Jay Beattie. In general I would hesitate to have straight pull spokes on a disk brake bike. All of he angles are wrong. No, they're not. Given 24 holes [1] the angle between adjacent spokes is exactly the same as any other two-cross 24h wheel. [1]I don't know rider weight or application but 24 is a smallish spoke count for many riders. Andrew, you're not speaking of a straight pull wheel I suspect. Front wheels with straight pull spokes and disks pull the spokes at almost 90 degrees from their line of entry into the hub. (and the Campy only have 12 spokes don't they?) I know the older Campy wheels I have, have straight pull spokes and only 18 spokes. Right but that's a different discussion. 24 hole two cross wheels, whether bent head or straight pull, have the same spoke angle. Radial, asymmetric rim drill and so on are another thing entirely. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |
