Assymetric wheel lacing
Greetings.
I stand before the task of lacing the rear wheel for my brand new downhill/all-mountain bike. 26", long travel suspension. I wonder if there is a benefit to lace the wheel assymetrically - that is 2x on the disc brake side and 4x for best torque transfer on the drive side(there is going to be 36 tooth sprocket on the rear, with 22 front there are going to be some serious torque values to handle) Is there a benefit, other then looks, for this approach? Regards -- Adam Kadlubek |

Regards -- Adam Kadlubek with 4x you'll probably end up with a nasty bend in the spoke where it exits the spokenipple -- /Marten info(apestaartje)m-gineering(punt)nl |

Regards -- Adam Kadlubek No benefit as with any disc brake hub, it is stiff from one side to the other. 36 hole, built well on an appropriate rim, laced 3 cross. |

I'm pretty sure I can't do that-- I can stop a lot faster, even with one brake, than I can get up to speed. That said, even cross-two lacing should have plenty of leverage. I'd use normal cross-three lacing on both sides if I didn't already have the spokes for some other lacing pattern. Is there a benefit, other then looks, for this approach? Cross-two is better than cross-three or cross-four if you want to lace all on the same side of the flange to help compensate for wheel dish. This is often referred to as Gilmer "Race Lace", and it works. I think the original version was all elbows-out on both sides of the hub for maximum gross bracing angle, but I am more likely to use all elbows-in on the left and all elbows-out on the right for minimum dish (if that allows acceptable clearance to the chain and inside sprocket/ freewheel body). Oddly, cross-five on a 36-spoke wheel works well for all-in or all-out lacing. Race Lace is sensitive to flange diameter, so you may want to do a drawing and figure out what you're up against.

Chris 3 cross 14 gauge spokes 32 hole hub I use this combo on the shore and weigh 230 lbs. and have never had a problem with my wheels because of weakness now impacting trees at high speed well thats another thing. |
