Cassette not fitted correctly?

After refitting the back wheel on my 4 week old Revolution Triad 2.0 that I bought through Edinburgh Bicycle Co-op (they'd fitted the direction specific Conti Speedking's the same way round both front and rear - and also on my mate's Triad 2.0 too...) I was trying to work out why my rear disc was catching the brake pads when I noticed that the cassette has a bit of a wobble going on when the wheel is turning. It's not a massive amount, but is very noticable.

I'm worried that this could be a buckled hub (unlikely) or just an incorrectly fitted cassette?

When looking from the rear of the bike and spinning the wheel, the disc also moves slightly from side to side causing the dragging on the pads.

Is this a common thing? Has anyone else had this problem? The bike should be going back for it's free 1st service in a few weeks, am I likely to cause any damage by riding it in this condition? I only ride around 25 miles a week on generally fairly flat coastal paths while trying to get fit!)

Cheers

    cassettes do have sidewards movement.

    the disc should not.

    mention the disc to them when you take it in for its service.

    Wow! That was a quick response!!

    Cheers for that Nicklouse, the disc is solid to the hub but it doesn't run as true as I'd like. I thought that maybe the disc was warped or not torqued up correctly.

    However after removing it, cleaning all ajoing surfaces with isopropyl and refitting, it's exactly the same - and it seems to catch on the same part of the wheel revolution (using the Shimano logo and little yellow quality control sticker on the hub).

    I worried if I take it back that they'll say it's wear and tear - the bike's only done 115 miles and it definately hasn't been abused! I've had a few bikes in my time, granted I've been out of cycling for about 12 years(!), but I've never seen a hub do that before...

    Unrelated but how is the bike? I came very near to buying one (found a bargain elsewhere hence no purchase). The Triad series seemed a lot of bike for not a lot of money.

    Hi MattRhino

    Sorry it took so long to respond!

    Yeah, I love my Triad! For 600 notes it's a steal to be honest. When you think that for the same price you can have a Specialized Rockhopper Disc which comes with 24 speed Acera/Alivio transmission and a Tora fork (fair enough, the M4 frame is fantastic!) but for the same price you get a 27 speed SRAM X7 level transmission (X-5 shifters though) and a Recon air fork, it's a bloody good deal.

    The frame is a peice of artwork in itself though, and is made by Merida so it's up to the job. The profiling on the downtube + the strengthening ridge along the bottom, and the shape of the chainstays show that it's a well designed peice of kit.

    The finishing kit is all top notch too - it may be mostly Truvative's XR equipment (stem, handlebars and seatpost), but it does the job and looks good too - I know brand name stuff isn't always great just because it has a brand name on it, but it adds to the feeling of quality.

    The only changes I've made to mine (so far) are to add a pair or XT SPD's, a SRAM gold Powerlink and a Specialized BG Avatar saddle (apart from a Specialized MTB Rib Bottle Cage, a Blackburn pump and a Crud Catcher ZX...)

    I have had a couple of teething problems though - the bottom bracket (Truvative GXP Firex) wasn't tightened properly by the shop on the non-drive side and as is the topic of this post, my rear hub appears to be buckled, I also don't think the rear wheel's tensioned particularly well and the Juicy 3's make some strange sounds (but that's not a fault of the bike as all Juicy's seem to suffer from Turkey squawking unfortunately!). They also didn't fit the directional rear tyre the correct way either... It's all in the attention to detail!
