|Spoke length question for wheel building. Please help.||Ken of Fresno|
Aug 30, 2002 10:57 AM
I'm building a set of wheels and have two specific questions.
1. The spoke length calculations seem to be within 1 or 2 mms difference between the front and back wheel (F=294.6 Rnondrive=293.2 Rdrive=291.6). Can I just buy 1 box of 72 spokes all the same size (294mm) to do the job? It's much cheaper that way, as I can get a good deal on the box.
2. Can I use standard alloy nipples (not the extra long ones) with my rims?
Here's what I'm using:
Rim: Mavic CPX33
Hubs: Shimano Ultegra 9spd
Spokes: DT Competition 14/15
Lacing Pattern: Cross 3
If anyone has built wheels with these same components I'd love to hear what you did (spoke lenghts f/r, standart/extralong nips, etc.)

|Based on your numbers, the 294's would be way too long on the rear drive side. Put it this way, I wouldn't do it.|
|look at performancebikes, they sell those spokes...||PeterRider|

|... packaged in smaller quantities, for what seems to be a good price. Plus there are 20% coupons valid until tomorrow, in the outside buyer magazine's guide (I posted 2 of those coupons yesterday in the hot deals forum). |
I don't know how is the customer service for spokes, if they mess orders or not... but I ordered some yesterday (for lacing CXP33 to chorus front/dura-ace rear). We'll see.

|Usually within a millimeter or two is OK but to save $3-5 on the spokes and then possibly have building problems and always wonder if a spoke is too short, etc while riding - I don't think its worth it.
CXP33 take regular nipples (I just build up 2 sets of wheels with them in the last month of so - both 28 hole on DA - 1 all 3X DT 14/15/14 (for a friend) and one for myself radial front DR Revolutions & 3X drive 14/15/14 DT - radial non-drive Revolutions).
|What spoke lengths did you use on the 3x DA wheel?||Ken of Fresno|

|I don't think there would be any difference for Ultegra.

|Indeed, there would not be any difference between 105/ultegra/da hubs - flange size and offset is the same.
I would give you the spoke sizes I used for both build ups but as the wheels I've recently built with CXP33's were 28 hole, thus the spoke lengths would not be applicable to your scenario. A quick look shows that you should need 294 front, 292 left rear and 290 drive for a 3X 32 hole set up. Just get the correct lengths and sleep better.

|Waiting for the end of a spoke that sticks out the back of the nipple to work its way through the rim strip and blow the tire.|

|There is a bit more room for error with Wheelsmith spokes than with DT spokes--Wheelsmith spokes have slightly longer nipples. I'd just buy the right size, though... (and I prefer brass nips, especially on the rear drive side)|| |
