Mavic Cosmos Noises / Old Rolf Sestiere Rims
I have a set of Mavic Cosmos wheels on the Litespeed that I bought
this year. The rear wheel started making a rythmic rubbing noise, not unlike what a dragging brake sounds like (it's not rubbing anything). It does not make the noise un-loaded, but I can replicate it by pressing down on the seat and pushing the bike along. I had my LBS tighten the spokes (the mechanic said he added almost 2 turns to each spoke to get them up to tension), which cured it for maybe 30 miles. Recently the front wheel has started to creak when I stand up on the peddles. At first I thought it was the bottom bracket, so I removed it and put new Teflon tape on the threads. I also greased the seal and checked the peddles, which are nice and lubed, just to make sure. I checked the headset and headset bearings as well, just in case. I'm now about 93.7% sure it's the front wheel. I took the whole bike into my LBS (same mechanic that re-tensioned the spokes) Saturday, and he checked the spoke tension of both wheels, stating they were fine. He heard the noise when rolling it on the floor while putting weight on the seat. He told me that this is pretty common with Mavic wheels, that there is a pin in the rim used to hold the wheel together for welding that can get loose and make noise, and the alluminum eyelets get loose and make noise. I did some research on Monday on the net, and found that noisy Mavic rims were not unusual. I found that I might be able to remove the pins, and that cleaning and oiling the eyelets might help with the noise, but it was usually a short lived fix. My rims have about 1,500 miles on them. My GF has a set of Rolf Sestiere wheels she took off because the rims are getting pretty scored. Well, that and she wanted new wheels (Rolf Prima Vector's). Sunday I mounted up new Michlen ProRace tires with new tubes onto the old Sestiere wheels. I have not ridden the bike yet with the Rolf's, but they look nice and are nice and light (compared to the Mavic's). I'm a little concerend about the brake area; although they are not that thin yet, they are groved pretty bad. Questions: 1) Is it normal for Mavic rims (or just low-end Mavic rims) to get noisy and stay that way? Are there any that are better than others? (i.e., would putting Open Pro rims on my Cosmos hubs be worthwhile?) Currently, I'm not impressed with the Mavics if they get this noisy after only 1,500 miles. I am going to de-mpunt the tires and try all the fixes I found on the web. 2) Can I get new rims for the Rolf's? These are the ones built by Trek, and Rolf Prima does not service them according to their website. Trek now does Bontrager wheels (the Race Xlite are very like these Rolf's). The Rolf's use "paired spokes" and are 20/24 spoke. If I am going to invest money, my preference would be to get the Rolf's re-rimmed, and either sell the Cosmos or keep them for winter spares. Thanks, Ken Newbie Roadie |

Questions:
1) Is it normal for Mavic rims (or just low-end Mavic rims) to get noisy and stay that way? Are there any that are better than others? (i.e., would putting Open Pro rims on my Cosmos hubs be worthwhile?) Currently, I'm not impressed with the Mavics if they get this noisy after only 1,500 miles. I am going to de-mpunt the tires and try all the fixes I found on the web. I have a set of Mavics and started to hear the clicking/rub noise around about 1000 miles. I think I found the fix here, but it may have been somewhere else, but a very small drop of chain oil in each eyelet actually FIXED the noise (for about a year). They just started up again about a month ago so I re-applied the drops (fixed again). Someone here said that riding in wet weather will push the oil out faster and you will have to put drops in more frequently, but I try to stay out of the rain. Fair weather rider unless caught in a storm. I've ridden Mavic wheels for years because they are everywhere. Last year I got away from Mavics on my mountain bike (Bontrager), and I've been really happy with the decision. Still have the Mavics on my road bike, but just itching to swap them out with some Bonts. As you might guess, there is no Mavic in my future. |

KD- I have a set of Mavic Cosmos wheels on the Litespeed that I bought
this year. BRBR These hubs and nipples are really noisy. Have the LBS take apart both hubs, clean, oil and grease. Also a bit of lube where the sppkes enter the rima dna hub. Geezzz..go see a wheelbuilder of note that will take some hubs, Campagnolo or shimano, some rims, like those from Velocity and design a wheelset specifically for you and your GF. Light, reliable, common parts, cheaper. http://www.velocityusa.com Peter Chisholm Vecchio's Bicicletteria 1833 Pearl St. Boulder, CO, 80302 (303)440-3535 http://www.vecchios.com "Ruote convenzionali costruite eccezionalmente bene" |

At least I can hear the GF coming up behind me (sledom) or know when I'm catching her! Ken Consider simply sanding the Rolfs smooth, and check that the brake pads are not the evil kind: http://www.chainreaction.com/brakeshoes.htm Also maybe get some of that special grease for the star ratchet. Really makes it a lot quieter. |

"Qui si parla Campagnolo " wrote . Have the LBS take

I've noticed that Sheldon has come under some critcism for suggesting blue Loctite on his website. Are commercial products like SpokePrep better than off-the-hardware-store-shelf products? Thanks, Bow |

bow- What oil/grease/lube do you recommend on spokes and nipples when
building a new wheel? BRBR I use Mobil One for the nipple to rim interface and boiled lindseed oil for the spoke to nipple interface. NEVER loctite. Spocprep stuff, like wheelsmith smell like ammonia(?) and are expensive. Any kinda lube will work, But the build is the most important part.

Check the thickness of the brake surfaces, they can wear too thin and fail catastrophically. Sanding isn't recommended. You can get the rims replaced with the Bontrager as they are nearly identical. Unless you can find an inside source, its shipping off to Trek/Bontrager. What you need to look at in addition is cracking of the spoke holes. The Sestrieres have this problem. Special grease? Just use Phil Wood. Make sure all the old stuff is cleaned out. -- Weisse Luft |

Ken Try a Trek dealer; I think Trek carries little tubs of the DT special grease. From page 4 in this document http://www.dtswiss.com/data/files/MA...0105140837.pdf "DT special grease Art.Nr. vFett20" Same document, from page 24: "CAUTION : Never use normal grease in the freewheel mechanism, because this will impair the function of the star ratchet teeth. Only use DT Swiss recommended special grease for this procedure !" |
