mavic wheels/ spoke tension

hey, i was cleaning my brake pad surface on my crosslands the other day and noticed that some spokes felt really loose*slackwise* and some were tite...

also just now noticing with my new sd ultimates that when i take a turn with alot of lean that the rim will rub the pads

also when im going through some mud/water/etc. i can really hear the pads rubbing


what should i do...

should i go have the spokes retensioned asap.. i dont want to end up with hops and bends in my wheels... these are relatively new less than 1000miles on them so far... alot of aggressive xc riding is all.

Front or rear wheel, or both?

On a rear wheel the drive-side spokes will be noticeably tighter than the non-drive side. In many cases the non-drive side will almost feel slack.

Go to the Mavic web-site and find out the applicable spoke tension for your rims and then see how yours compare. If yours are out of spec, then re-tensioning is critical to avoid spoke breakage or rim failure.

Even if you are not doing wheel building a spoke tensiometer ($60) is a great tool to have. Full spoke tension will make yor wheel last a lot longer. The tension should be even all around but +/- 10% is acceptable to achieve true shape.

This is usually where you would find this kind of information, but Mavic does not supply this on their public site. They do have a "dealers only" tech support site that you need user/password to access. The killer is that the dealer-only site is kind of a joke, and there is very little useful information. Another "feature" is that they calculate E.R.D. differently from the rest of the world. They don't account for the thickness of the nipple head. This is why you see "add 3mm" for Mavic rims in SpoCalc. E.R.D. is supposed to include that.

The tension spec asked for by the OP is 90-110kgF. That is what is stated on their site for ALL Mavic rims. If you call Mavic on the phone they will tell you the same thing. The $64 question is how Mavic has managed to get all of their rims to tension in the same range. If you tension your fronts to 110 on both sides and your rear to 110 on the drive side you'll be fine.

alright im pretty sure that i need to retension the spokes... because the both scrub when leaning to the right... the question is should i get a spoke tension measuring tool or should i just take them to the shop and have them retension them for half that price

If anyone wants to access the Mavic tech site at www.tech-mavic.com the username is mavic-com and the password is dealer.

There's nothing really earth-shattering there. Makes you wonder why they keep the information there from the consumers. Probably trying to protect their dealer network and their information advantage.
