Just a quick question.

I currently have a screw on freewheel, I'm looking to get a new rear wheel as I need a disc compatible hub.

The new wheels I have been looking at has a freehub, so I'd need to buy a cassette.

My query is - Are cassette lockrings included with the cassette?

Thanks for your help.

    yes they are.

    but the hub might not fit your frame. also does the frame have disc mounts?

    Yeah the frame has disc mounts. It's the RBK Radium. ( i know, i know ) It's actually not too bad

    I'm looking to upgrade to a 9 speed cassette, shifter, mech in the future. But it's currently 7 speed.

    Am i right in saying that I can get a wheel with a 8/9 speed freehub, and fit a spacer to run a 7 speed cassette until I upgrade?

    Drop out spacing is 135mm.

    yep you can.

    just checking on the dropout spacing :wink:

    Ok, cheers for your help.

    Slightly off topic, I just bought a set of Clarks twin pot front (203) and rear(185) disc brakes.

    On the reservoir cover it says use dot3 or dot4 fluid. does that mean they can be mixed, as i don't know what they were bled with at the factory.

    Also is there a specific bleed kit for Clarks brakes?

    you will need a 9 speed chain and maybe a new crank set

    DOT3, DOT4 and DOT5.1 can be mixed.

    Bleed kit? maybe what are the actual brakes. Pics?

    The brakes are Clarks twin pot hydraulic disc brakes.

    I've spoken with someone from the store I bought them from and they have said that there is no specific bleed kit.

    All you need is fluid, a syringe and a piece of hose - although that will mean that fluid will spill out of the the master cylinder when fluid is forced through.

    get an avid bleed kit as that will work on the lever.

    look the same as the Diatec sport brakes.

    careful where you but the casette as some sellers on an auction site i'm sure you've heard of dont sll them with lockrings, sram are a pain for not having them included on road cassettes which a lot of off road riders now use due to sprocket sizes

    I'll watch out for that.

    I think I'm gonna go for the Shimano bleed kit, as it comes with the bung for the master cylinder so that nothing spills, instead it is forced through a hole in the bung into a bottle.

    Plus I've seen it in use and know how it works.

    i would not be doing that as the rubbers will not like the fluid.

    shimano kits come with mineral oil.

    Ah right, I never thought about the damge the oil wouild do to it. In that case is there any other bleed kit that makes use of a bung on the master cylinder?

    first download the instructions (or take them out of the box)

    and see what it says about bleeding http://www.clarkscables.com/ should be there somewhere.

    Unfortunately, after speaking to Clarks they say that the manual is not available for download and that I'd have to go through the shop to get a manual ordered in which could take weeks.

    Basically it's an open system, so when the brake fluid is pushed in from the caliper up to the lever the excess brake fluid is going to spill over and go everywhere and create a contamination risk.

    What I'm after is a bleed kit that contains some sort of bung for the reservoir when open, which was why i was attracted to the shimano kit in the first place.

    But it's not a good idea.

    Differing DOT ratings mean that the fluids have different thermal stability levels and also absorb moisture at different rates.

    Theoretically yes you can mix different synthetic brake fluids but a good mechanic never will.

    You must NEVER mix synthetic fluid and mineral oil.
