I had my cassette come loose and the chain went into my spokes. This wheel was built by a master.
The wheel has a Chris king hub Sapim Spokes double butted spokes a velocity arrowheat rim. it has about 3k miles on it. 8 outside spokes where chewed up and one snapped.
Well I went to the closest shop (highest priced in town) and they wanted to rebuild the wheel for 40.00 and I guess replace the broken spokes (or maybe all of them) for another 20.00 and then goes on to tell me how soft the rim is and should be replaced. With a mavic cp33 rim for another 80.00
So the question is does the wheel need rebuilt and do I really need a new rim?
this is a disc brake wheel so no rim wear.

Unless the rim was tweaked severely (taco shell remove spokes and it stays that way) I'd say the rims is ok. As far as spokes go it may not be a bad idea to replace them or at least all the bad ones but if the rim was quite out of true and stressed the other spokes replacing all at once would be best for a reliable service.

steveknight

the rim is still perfectly true and no problems or even scratches. but yes replace all the spokes makes sense. sometimes the advice from this shop as made me wonder over the years.
I bought a cheaper wheel from them a few years ago that had a hump in it.
they have a huge amount of high end wheels hanging up. pretty limited on 36 spoke rims I think.

This is why I prefer to do my own wrenching. I'd almost be worried about letting them do it from what you say if it were me any other shops near you? They may not do the job I'd be expecting since you are not doing as they wish in hopes that something fails later to try and prove a point to you.... ya know what I mean, ask for the specs that they are going to tension spokes to so you can check when you get it back or at least they will think twice before not tensioning correctly.

building wheels is about the only thing I don't do. so I buy high quality hand built wheels .they don't usually need any work. till I screw them up anyway (G)
Yes a bunch of other shops. so I will hit a few tomorrow.

Steve, if I had the time, I'd rebuild it for you. Right now's not good- I've got a bazillion projects at work, and I'm trying to recondition two Tour Easies so I can sell them. I put new rims on both bikes- I'd rather spend some time and money and make sure the next owner is happy than have someone complain I'd done them wrong.

steveknight

I realized I can put my 26" wheel on as it has a disc brake. I have a spare wheel but it is not a disc brake so it would be a pain to have to put v brakes back on while the wheel is getting fixed.
I built a couple of wheels 15 years ago but I can't wrap my mind around it anymore.
I am a woodworker not a great mechanic (G)

Have Velocity Aerohead wheel, 36H, on a tandem (utilize V-brake) with 23,000+ miles. on it.

steveknight

yes they are great rims. never had a problem. but I have had a mavic fail and a poor built mavic too.

Jeff Wills

Yeah, but that's in Arizona. The Pacific Northwest weather turns any grit into grinding paste:

one reason I like discs too much wet winter here. though I wish I could put a disc on front on my gold rush.

The question I'd be asking is "Why did the cassette come loose?" Seems to me if a bike is properly maintained by either the LBS or yourself that would never happen. It should be tightened down to proper torque and that and other bolts etc should be checked on a regular basis. PM is worth its weight in gold and can save you from having some of that hard earned gold removed from your pocket at inopportune times and in ways not of your choosing.

Anyway hope you get it fixed up to ride.

The high end nature of your components or build don't mean a lot here as that has little to do with what happened from what you say. Why on earth did your lockring come loose? Your fault? Someone else's?

If you're going to rely on a shop to build wheels for you, then either take their advice or get a second opinion from someone who can at least see the wheel instead of an internet post. Maybe if you had posted a pic or something, but if only one spoke broke it's hard to understand how tweaked the rim could be.

The prices aren't out of line for the work, although it's probably a good idea to know specifics on the spoke replacement and cost (if you're getting all new Sapim db spokes for 20.00 that's pretty good).

DannoXYZ 

Look up the torque specs on the lockring. VERY few people tighten it adequately. The serrations help somewhat, but without proper torque, they'll still loosen.

bikinfool

I think many people are surprised when they actually understand the torque recommendation...

rodrigaj

Campy lockring : 50N-m printed right on the ring. The shops never get it right. I always retorque, with a torque wrench, when I get a wheel back from servicing.

HillRider

Yep, and Shimano recommends 40N-m also engraved right on the lockring. It is amazing how tight that really is and without a torque wrench most mechanics won't get anywhere near it.

BTW, I have no experience with Velocity rims except to hear they are good. I can personally recommend the Mavic CXP-33 rim as I have had excellent service from several of them, ridden in some pretty nasty conditions too.

bobbyahines

If i give a customer an evaluation/recommendation/estimate, I wouldn't be offended in the slightest if they got a second opinion. Also, don't forget that, as a customer, you control the handlebars on the repairs (*for the most part). Get a couple of opinions, then take it to your most trusted shop and tell them exactly what you want done.

*In this I mean that I would refuse a customer request that created unsafe conditions.

I goofed on the cassette. I was having chain skipping on the last cassette but only had 3k miles on it so I was testing the new cassette to see if it was it or something else. I forgot to fully tighten it afterward.
one spoke snapped the other outside spokes are chewed up. I was going pretty fast when it happened. I would never trust them not to fail later. here is a pic not great but all I have at home is my cell phone

Rick Rubin

You should only have to replace the spokes which are damaged and switching the Aerohead for that Mavic rim is not necessary or worth it and generally not cool. 40 bucks for a rebuild isnt bad, but 20 for the spokes seems a bit high (I know those Sapims get expensive though)

San Rensho 

The recommended repairs are perfectly reasonable for a bike shop, but you might be able to get away with less if you do it yourself.

The bike shop has to warranty its work so to give you a warranty, it has to replace everything, which is perfectly reasonable and the "best practice" way of doing it.. As others have said, you may not need a rim, so spokes and truing might be the fix.

steveknight

went to a really good one person shop that I used to go to. the fellow is a really nice guy but does not like bents. he has a master wheelsmith that comes in several times a week.
66 to do all the work and parts. he said he needs to remove all the spokes on the one bad side. but no need as others have said to replace the rim.
even though the shop I went to is the most expensive and one of the bigger shops here I guess they have a large turnover in mechanics and really don't pay them well. they mostly do assembly. makes since I have never really had good service there.

bikinfool

Lotsa nice guys don't like 'bents (a horrific version of a bicycle IMHO ). Lotsa nice guys even blame others when they don't know WTF they are doing/talking about...

Ranger63

If your shop is the highest priced in your area, send me the address!
Seriously, the costs you mentioned are (in my neck of the woods anyway) very reasonable.
I'd go with new spokes all around on the wheel.
As another poster advised, remove the spokes and see if the rim is still taco'd
I've had at least one local shop try to sell me on a entire new wheelset (at around $600.)when all it took was some tweaking of the bladed spokes by a guy who knew how to.

steveknight

thier price was reasonable but they tried selling me a rim I did not need. the rim was perfectly true thats what really got me.
hell this wheel set was 800.00 I think. I got the impression that my wheels sucked and he wanted to make them better.
well now a master has the wheel and he will do a good job.
