Cassette question

[wam68]

Hi all,
Last night I fitted a new 10 speed 105 cassette to my Fulcrum Racing 3 wheel. The hub takes an 11 speed cassette but came with a spacer to fit a 10 speed. So spacer went on first and then the new cassette. I then took it out for a run. DISASTER. Despite all best efforts it just will not rest on the cogs on the highest gear ( smallest cog ) but keeps bouncing up and down and slipping. I have adjusted and adjusted and adjusted so more. Does anyone know what the $%&* is going on with it. What have I not done

Sounds like you need to re-adjust the derailleur

Sounds like the limit screw may need a tweak?

Guys I have spent 2 hours at the limit crew and the adjuster and it either gets worse or just flips of the cogs. It just will not rest in the mall cog. It changes perfectly into all other gears.

Loosen the cable slightly as it might be at full stretch on the 2nd smallest cog .

The 105 cassette should have come with a thin spacer which is required when replacing (for example) a Tiagra 10 speed cassette (in addition to any spacers required by the hub).

No spacers with the cassette. Came in a plain brown box from CRC. The only spacer used came with the hub

I'm sure it should have a spacer included.
Mine did, and it's required when replacing a Tiagra/'standard' cassette.

It's shown here too: http://si.shimano.com/php/download.php?file=pdf/ev/EV-CS-5700-3016.pdf
I'd have a word with CRC.

RebornBumbler you were right. Spoke with CRC and yes it should have come with a 1.0mm spacer which is fitted in addition to the 1.85mm spacer that came with the hub. They are sending it out ASAP. Thanks friend. This is why I joined Cycle Chat. You have no idea how close I came to going back on the cigs ! It had me completely baffled

I had exactly this with my 105 10 speed cassette on my Zonda's. Spacer with wheel for 10 speed cassette and spacer with cassette to fit even if on a 10 speed freehub. Seemed odd when doing so, but it is correct.

Did you fit a new chain as well?

Well did you?

 

[wam68]

No used a chain which I have from last summer. Have a new KMC ordered.

New cassettes don't like old chains very much so this won't be helping matters.

I agree but the cassette came first due to CRC having access to a teleporter ( light speed delivery). I am pretty certain now that the lack of a spacer was the problem although I may be eating my words over the weekend. Cheers

You will not notice a new cassette with an old chain at all. It will work as per normal.
