fitting a new cassette

Kingsmill1

I have purchased a set of fulcrum racing 7's to upgrade my bike, i have also ordered a new cassette but instead of the same one on the original bike I have ordered tiagra rather than sora ( I have made sure that is 9 speed and the same 12/27 on the back). I am going to keep the old wheels for winter and the turbo. Question how easy is it to fit the cassette on to the new hub , and where do i place the spacer will the instructions that come with the wheels explain all or is there some dark arts are work fitting the cassette. Have tools just need to make sure i dont balls it up with fitting the spacers in the wrong places.

Your new cassette should come with the documents above. They show you where to put the spacers.

it's easy

9-speed shimano cassettes have no spacer in the box

but read the instructions with the wheel, if it's a current model it's likely to be 11-speed compatible, so there'll be a spacer supplied with the wheel to match other speed cassettes

The hardest part is trying to work out which way the chain whip goes... and then worrying that you're putting too much pressure on the wrench to release it

(chain whip clockwise)

You don't need a chain whip to install a cassette. Just a splined tool and a wrench, or you can get all in one splined wrenches.

I would say for the cassette you are fitting to the wheels you bought Would be pretty much impossible to do incorrectly. the cogs will only go on one way and so long as you fit everything in the order it comes on the plastic hub holding it together and tighten it enough with the splined tool you cannot go wrong.

I think the OP mentions brand new wheels and a brand new cassette?

Good point, well made!

well everything is ready apart from one small detail the wheels have not arrived yet. I am going to change the chain while I'm at it as ive read its worth doing both at the same time. The current chain has done about 1800 miles and although I've checked it with a KMC chain checked the wear has not got the the point of no return. :http://www.bikeradar.com/forums/posting.php?mode=reply&f=40020&t=12953054#o

If I can fit a cassette in the work car park during a 5 minute break (I mostly suck at bike maintenance) then it must be easy.

Yep, providing you have the correct parts and the correct spline tool (plus chain whip if removing an old cassette) it is one of the easiest bits of bike maintenance you can do. One of the slots on each cog of the cassette is narrower than the others which ensures they all locate correctly on the hub. The only thing to watch out for (when removing a cassette) is the whip finally moving under pressure leaving you taking the skin off your knuckles!

I bought a park tool cassette tool which got mine straight off but when i put the new one on it was loose....nearly every ring was slack £2 later at lbs and sorted. God knows how I couldn't get it right. Any ideas?

Kieran_Burns

Yup - you forgot to put the spacer rings in....

Great time of to follow the rule that requires you to support your LBS.

Walked into mine with two wheels and two cassettes. Both fitted in 5 minutes total for no charge as I am a regular.
I insisted on buying the cake though.
