edited January 2010 in MTB buying advice
I am looking for some different MTB wheels w discs and came across these on Ebay.
Link to ebay

I have tried the search function looking for magnesium wheels (and cast) on this forum and google and do not seem to see anything quite like it.

Weight is listed as 1400g but as I don't know what any spoked wheel weighs maybe that is really heavy.

Motorbikes went to cast alloy wheels years ago.

Any comments about these? Avoid or have a go?

    Magnesium cast wheels on motorbikes tend to be on high end, high performance bikes and not offroad bikes that need to be a little more forgiving.

    yes they do use them on road bikes but not motocross or enduro bikes ect theys till use spokes.

    a freind has a wheel off his cbr in his garage that broke when he hit a pot hole send him to the tarmac and making a mess of his bike, the whole rime broke from the inner part of the wheel.

    Heavy and they look awful....
  • I know that the weight is a summation of both wheels.

    If somebody can tell me the weight of a single front OR rear wheel I can do the maths on the likely weight addition from 2 wheels.

    Motorcycles have cast alloy wheels for years, that is partly so that they can go to tubeless tyres (no spoke holes to seal). I have been riding motorcycles with Mag wheels for 25 years and have never had a wheel bent / break just through hitting a curb. (some have bent after hitting cars at speed but a bent rim was the least of my worries).

    Is there evidence that cast mag wheels on mountain bikes fail under road or off road riding conditions?

  • not particularly confidence inspiring hwhen the only pictures of them they have are on Folding bikes!!
    a set of Mavic crossmax wheels for example (attainable for a similar price) come in at 1905g for the pair, i have Xero session Free ride wheels and they are 2kg, 900g front and 1100g rear, significantly lighter!!

    Why on earth do you want to ride with wheels that are that heavy..2650g for a pair...regular wheels are anywhere from 1300g (pair - expensive (ish)) to probably around 1800-1900g pair (mavic crossride/ Shimano MT15) sub £150 for Mavics and sub £100 for Shimano. You will be limited on what you can get if you want both V-brake and Disc rims though. maybe better have some custom built to your spec.

    lets say that those Mag wheels are over 600g too heavy. compared to an average machine assembled wheel set.
    and they are about a 1kg too heavy than a fair set of hand built wheels.

    a good set of XC wheels will be around 1200gfor the pair.

    even an early set of Shimano wheels were lighter than those at 2100g a pair.

    and when you do damage something the whole wheel is trash.

  • Thanks for all your help guys. I take the comments on board and luckily the local bike shop have managed to straighten my normal rims when I thought they were unserviceable.

    It does seem pretty pointless arguing about the odd 500 grams when my weight went from 78 to 89kg following a motorcycle crash last August. I had ridden MTB 2000 miles to work b4 that in 2009. (over 8 months, not all in one go :-))

    500g weight loss on wheels is very noticeable, 500g off your person is not.
  • yeah 500g off the wheels makes a Lot of difference!!

    Trust me you would definitley notice 500g on a set of wheels, i noticed dropping 200g on tyres and i'm no light weight whippet either.

    Agreed, you can say "It's only 500g", but if you're buying new wheels, why choose to buy ones that are weaker, heavier and more expensive than Mavic Crossrides, for example.
