Ultegra 6700 wheels - correct spoke tension

andyeb

Does anyone know what the correct spoke tension is for the Shimano Ultegra 6700 wheel set? I've been searching online but haven't managed to find this info. As the wheels have a low spoke count, I'm expecting that usual rules of thumb do not apply.

I'm asking because I had a rear spoke go, causing the wheel to go massively out of alignment, to the point the wheel would not rotate in the frame and slightly damaging the frame in the process.

I've replaced the spoke and got the wheel true again, but I want to check all the rest of the spokes in the wheel. Currently I use the wheel as my turbo wheel, but would like to press it back into service when the weather improves.

I weigh 69Kg, if that makes any difference.

thanks,

Andrew

If you don't have a gauge calibrated for Shimano spokes is guesswork... if the Shimano manuals don't help, then you probably need 1300 N on the drive side and whatever comes on the non drive side

Thanks for your help. I finally managed to track down the dealers PDF manual here: http://si.shimano.com/php/download.php? ... 01-ENG.pdf

Which states the following tensions:

Front: 980-1400N
Rear (sprocket) side: 1000-1600N
Left side: 600-1100N

On my Park Tools TM-1 spoke tension meter, these values correspond to 98-160, which do indeed tally with the conversion table provided by Park Tools.

So your guestimate was bang on!

Finally - if I'm a lightish rider, would I be right in assuming I should go for low-end values to start with?

It's a very wide range, aim for somewhere in the middle
