More help please? |
My 2 yo mountain bike has been making noise recently, so I took off the rear wheel aswmbly(where the noise was coming from) and noticed that there was a spacer ring out of place. i pulled it out and found that it was badly damaged and was probably causing the incessant noise as well as the occasional lock-ups of the rear wheel. I am not entirely sure what it is called or where to get another on. It is a curved spacer ring that sits back in the hub assembly underneath the sprockets. If you could tell me what it is called (if it has a name) or where to get another one, that would be great. Hey Kremer- Dude, I've had lots of trouble with rear hubs on mtbikes and road bikes and it is always expensive. I've screwed one up before messing with it and it cost me more than I care to admit. Take my advice and take it to a bike shop and have the mechanic look at it. Don't take it to a big expensive bike shop that has name brands like Trek plastered all over it. Look for a bike shop that looks locally owned and with somebody you can trust. Good luck! Bobster Is it plastic or metal? If it's plastic it was probably the disc that sits between the spokes and the gears to protect the spokes from the chain in case of poor gear adjustment. It is called a spoke protector, although some people call it a Fred Guard. It's usually about the size of the largest cog. They're held in place by three or four tiny plastic tabs. They tend to only last a year or two, then become very brittle, break, make noise, and sometimes catch the gears and cause them to "lock up" because the wheel is unable to coast. They are not essential, as long as you keep your rear derailleur adjusted properly although you can get a new one at a bike shop if you wish. Experienced riders tend to get rid of them due to the problems above. They can sometimes be removed at home by simply cutting/tearing them apart. Putting a new one on (or removing the old one more easily) involves taking off the gears. If your part is metal, or smaller than I described, please provide more details and a hub brand/model. Most small metal spacers are involved in holding the gears in place. Losing one would mean your gears would be able to flop around which I think you would have noticed. There are also metal dust caps that cover some bearings. They aren't much bigger around than the axle. Having one out of place allows bearing contamination. Simply put..it is a spoke protector. It keeps the rear derrailleur from hitting the spokes if there is an overshift of the derailleur towards the wheel. The overshift is caused by a combination of two things. 1, the limit screws on the rear derrailleur are set improperly, and 2 the cable tension on the rear derrailleur is improper as well. To solve this issue, you can attempt to adjust the limit screws on the derrailleur, and adjust the cable tension, however, if you have not don this, I would not reccommend it, for you might end up adjusting the derrailleur into the wheel even more. However, if you are insistant on experimenting on your bike, andpotentially ruining a wheel/derrailleur goto the link for some information that you can experiment with. If that does not work ( and what I truly suggest) take your bike to a shop that has experienced and knowleddgable staff to repair your bike :) http://www.bikewebsite.com/dercable.htm... blackbarbicycles.com |
