bike parts on line

gentlemen,

doing a few repairs to a raleigh genesis at the moment, albeit it a male 15speed version rather of the ebay link rather than a 10 speed, bike is about 10yrs old

bike has been a loyal servant and has covered a lot of mileage, gears brakes etc all perfect due to it being kept inside, miles better than those €100 bikes from LIDL

need a new rear sproket new chain and new frount sproket, everything begins slipping as soon as you try to pick up any bit of speed

BTW what is the technical name for these rear sproket appears to be called rear cassette, can't figure out the name for the frount sproket was looking on ebay and didn't find anything

rear sproket has 14 teeth on cog 1 and 28 on cog 5
frount sproket has 28 teeth on cog 1 and 49 on cog 5, 12mm square hole in sproket

anyone know a good source for these on line?

to remove the rear sproket is it a case of hitting it with chisel and hammer or is there a more scientific method, if I bring the wheel to cycle shop will they have a special tool to remove it? can't see anything to catch with a spanner or socket

regards,
aidan

the name for the front 'sprocket' is a chainring/chainwheel or rather a crankset is to cassette, as sprocket is to chainring..if you know what I mean.

and the tool you need is a one trick pony..you can only use it for this and nothing else, actually its 2 tools, one is inserted into the teeth you can see when you take the wheel off bike, and the other tool is a chainwhip, which serves as the tool to apply torque and remove the cassette.

Hmm.. yeah.

The rear cogs are collectively called a cassette. The front cogs are called chainrings. A cassette removal tool is used in conjunction with a chain whip to unscrew the cassette. You will need a chaintool that is specific to your cassette. The best bet is to head into a bike shop with the wheel and ask them for a cassette tool which will fit your cassette. The chain whips are standard.

You will not have a 5 speed cassette, it will be a 5 speed freewheel such as http://www.halfords.ie/webapp/wcs/stores/servlet/product_storeId_11101_catalogId_15551_productId_181166_langId_-1_categoryId_212383 this unscrews using one of these http://www.halfords.ie/webapp/wcs/stores/servlet/product_storeId_11101_catalogId_15551_productId_714315_langId_-1_categoryId_212639 you don't need a chainwhip. If you don't envisage using the tool for some years then pop into a LBS, it takes seconds to remove and replace.
