COuld I fit a 8 speed casste on a MTB wheel with an 9 speed casette? |
I found this wheel here : http://cgi.ebay.co.uk/26-inch-rear-bicyc... Now I just wondered if I could fit it onto my Bike It has an 8 speed gear lever and caliper brakes I did email the seller some time ago , I hadnt got a repply Not knowing all the details of all your components, I can't say for sure, but I recently broke a rim, and had to cannibalize an old bike to get mine running. My 9 speed cassette would not fit the old 8 speed wheel, so I ended up relacing my hub onto the cannibalized rim. Possibly, depends if you the movement on the deraileur to go the extra few mm over. Yes an 8 speed Shimano/SRAM cassette would fit. Shimano compatible 8 and 9 speed freehubs are the same size. The cogs on the 9 speed cassette are just a bit narrower to fit one more cog. More details are needed: (Like, are both cassettes of the same brand?) But if you are trying to get a 8 speed cassette instead of a 9, then it could be done easierly, but adjustment of the rear derailleur. Fitting a 9 speed cassette in the place of a 8 speed one could be possible, (but then again, impossible). Fine tuning of your rear shifting mechanism will also have to be done very carefully. Most likely, you will have to change your speed gear level, or just miss one of the 9 gears. (Is it worth it? Do you get a better gear ratio?). The calliper brakes are no problem, for they have nothing to do with a 8 or 9 speed gears. Here is a good site to get some answers, I hope: www.bicycledoctor.co.uk/index.... And another one: www.sheldonbrown.com/derailer-... Another option is to ask at a bike shop to a good mechanic, giving him all the information you can. (Like cassette brand, MTB wheel make, etc.) Good luck to you- Josh has the correct answer. An 8 and 9 speed free-hubs are interchangeable. You have to use the 8 speed cassette on the new wheel of course. EDIT: If the rim is disk only the next answer is correct. The freehub will work fine but disk only rims do not have a proper braking surface for rim brakes. Good catch! No, This is a DISK SPECIFIC RIM. Please read the note just above the bullet points. (You Are Bidding On A Complete 26Inch Rear Mountain Bike Disc Specific Wheel.) However if you want to buy them; 1) The hubs are designed so that 8 speed or 9 speed cassettes can be used. The only issue is that you use a compatible shifter, IE. 8spd shifter for a 8 spd cassette. 2) Being they are "disk only" you would need to change your brakes over to disk. (Caliper brakes will not work with these rims) 3) You could swap your current rims and re-lace them to the hubs you are considering on E-bay. You don't fit a cassette on the rim, you fit it on the hub. The ad mentions a Shimano hub. In theory at least, this is possible. You'd need to change the axle to a longer one and the freehub body to the correct one. A 7 speed rear wheel is too narrow for the spacing for your frame if your current frame is 8 speed. Note that wheels are made of the rim (Mavic 234), hub (Shimano) and spokes, so in essence the rim has nothing to do with the cassette. |
