XT cassette chewing up Hope Pro2 freewheel.

I had problems removing the XT cassette (M760) from my Hope Pro2. The cause seems to be the cogs that aren't part of the carrier chewing into the freewheel. No previous damage to the freewheel and the lock ring torqued up to 40NM.

Is this a common problem? If so I might as well change to a steel freewheel as this damage happened within 100 miles.

    yes the lose cogs do cut them up a bit but less that the big ones if they are loose.

    At the current rate the freewheel will only last 300 miles so I guess once it's worn then It's back to good old steel.

    a steel upgrade can be purchased from CRC thats what ill be doing to have the cassette i want and none of the breaking or wearing

    once its marked it won't generally get much worse

    I recently spoke to Hope when i broke my freehub mechanism in my Pro II (two of the springs snapped) and asked them about the marking on my alloy freehub body from using a non-spider cassette, they said it doesn't really matter as it won't get worse once its marked

    if you look through the rear off the cassette you will see four arms. Thats the spider :P

    I thought you could only get alu spidered cassettes for Pro 2 or am i getting the wrong info from people?

    its easier just to upgrade the free hub to steel then?so i can run a steel cassette

    basically the stock Pro II freehub body is a relatively soft aluminium alloy and can get marked / scarred by using a cheaper cassette such as Shimano Deore or SRAM PG-970, as both of these are built by rivetting together a stack of steel cogs

    the more expensive "spider" cassettes like SRAM PG-990, Shimano Xt or XTR (£100!!!) have the larger cogs carried on an aluminium alloy "spider" and only the smaller sprockets are loosely fitted onto the freehub body before tightening the cassette lock-ring

    because the spider style cassettes use aluminium alloy for the spider, its more friendly (softer) towards the Pro II freehub body, and as the spider style casssetes are stiffer under load (plus lighter) you don't get the marking on the body...

    I have seen production bikes like Orange fitted with non-spider cassettes and with Pro II hubs, so its not always a consumer mistake

    you can add the steel body, but the beauty of the Pro II is its light weight, which the steel body will alter

    Hope should produce a Ti freehub, like XTR.
  • rob colerob cole Posts: 706
    Ti is nice, but the costs of the raw material has gone through the roof

    for example, Profile have stopped making alot of their BMX parts in Ti because the costs of the Ti axles had almost doubled :shock:

    Ti bodies get marked, but not like the alloy ones.

    You'd have to go some to force a cog all the way through the freehub splines. Remember its a functional part, not a cosmetic part.
