Wheels

jpstar

Hi i had an accident on my bike on thursday and have busted my back wheel rim (i dont mean out of true i mean squashed ) so i need a new wheel unfortunately. Also me being a child and not having a job im very limited money wise aswell which makes the problem even worse. I looked on google and places like merlin cycles and cycle sport uk and have come up with these wheel sets;

(i couldnt get the name unless this is the name) Shimano disc compatible wheels, Shimano M475 hubs nd Mach MX 1 rims. £70 a pair

Bontrager select disc wheels £80 a pair

Shimano deore £80 a pair

(no name) shimano deore hubs, Mavic XM321 rims and DT spokes £45-50 a pair


Id just like you to do say what rims i should avoid, get or be wary of.

thanks again

What bike is it for, and how many gears?

jpstar

Specialized hardrock (not sure of the year no suspension tho) 7 gears although cant i just remove the gears cogs and put them on the new wheel?

supersonic

Ah, herein lies the problem: you need to find out if the gear cogs are a 'cassette' or a screw on 'freewheel'. 7 usually the latter.



See the difference? Need to make sure your gears will fit!

jpstar

ahh thankyou very much is there anyway you can tell with out removing the gears?

supersonic

Have to look very closely! Or post a close up pic on here.

i think they are freehub but all my spanners etc are in the garage and my garage has no light. they have a sort of cog pattern on the inside on the front so i think they are freehub

supersonic

If they are a freehub, then you are in business except for one thing: modern freehub wheelsets are for 8 and 9 speed cassettes (they are the same width). 7 speed is narrower overall. BUT you can get a spacer for it, so no problem really!

Do you run disc brakes?

jpstar

no atm im running cantilevers (my bike is that old but its in perfect condition) but i want to change them over with my other bike as i find them to weak so will change them to v brakes or change pads make them stronger but no i dont use disc brakes

Okay dokey. One more thing (the bike is a little older than I thought!). Measure the distance between the rear dropouts of the bike. The insides of the dropouts. Most wheels and frames are 135mm, some older bikes are 130 or 126.

If is 135, (and a cassette!) then I'd get these:

If not 135, but is 130 and your frame is made of steel, the frame could be 'bent' outwards to fit.

And, remember that you can buy one wheel, instead of splashing out on both.

OR,

buy a new rim for about 20 quid, and get a local bike shop to build it onto your current hub.

jpstar

they are roughly 135 im guessing i used an old material tapemeasure that i grabbed off the side and rushed it in the dark with a torch. thanks ill get those you suggested. also are they suitable for xc aswell and will they fit any front fork? and will they work with quick release?

supersonic

Yes, yes and yes.

But as yeehaa says, you may be able to find just one wheel, but the pair I suggest is very good for the money.

jpstar

yh i could do that im just wondering what one to get now the rim and get the shop to build it or the deores.

supersonic

The shop would charge you about 20 quid for the build, plus spokes, and you would still have an old hub! An option, but the shop build price makes it less appealing.

jpstar

yh that may be a tad expensive especially as my shop can charge quite a bit fpr things like that. i think i will just buy them off merlincycles

supersonic

Ok, but double check the freehub/freewheel thing.

jpstar

yh ill take it down the shop see if i can get those wheels cheaper as my shop is closing down so ill bargain with them see if i can get them cheaper
