Are you sure those rings will fit your crank?
I would expect that bike is equipped with 130MM rings and the ones you list are 104MM

if i were to ditch the chain ring and stay with the one thats on it, could i use a tiagra chain with the tiagra cassettes and tiagra rear derailleur or will i have to use a tiagra front derailleur too? it has a normal shimano original front deraileur on it now

sorry for bad english

thanks

Get a SRAM chain. The rear derailler can be a short cage one if you dont have a wide gear range.

just to make sure everyone understands!

i want to keep my:
crank arm, front derailleur and chainrings from my claud butler san remo road bike

i want to put on:
shimano tiagra cassettes and rear derailleur and chain

problems:
what chain to get and what size and gear ratio to get on the derailleur ad cassettes!

PS: anyone know how to paint wheels. from what i can tell its normal steel spokes. i was thinkin of sanding them then spraying them with normal spraypaint. i dont know how many layers or if i should laquer thow. any ideas on how to remove a really annoying sticker thats well stuck onto the wheel to??

thanks, ben

Then why did you post a link to chain rings?

Why not tell us what you have, instead of us trying to guess?
Is it a double or triple chain ring.
How many cogs in the back and what are the smallest & largest sizes?
Is it a cassette or a Free Wheel.

Also, what are you trying to accomplish?

even a 10 speed chain will work fine i guess. I'm running a campy ten speed in a shimano triple mtb setup.

Thanks

Also, what are you trying to accomplish?
double chain ring
7 cogs at the back casstettes. i cant tell what kind of cassettes they are becuase they are completely covered in stuck on oil...

basically i dont understand what i should do regarding short cage/long cage on the rear derailleur side and on the cassette side what should i do with the ratios. also will it matter if i change from 7 cassettes to 8 or 9 if im using the stock crank and front derailleur with a tiagra rear derailleur.

sorry im a noob but i need help!!!!

To change to an 8, 9, or 10-speed cassette you would have to replace the freehub or complete hub, shifters if indexed, and chain to match the cassette. The cassette needs to match the shifters. This would be a considerable expense.

You can probably find a replacement 7-speed cassette (or freewheel), the size of the cassette (number of teeth) should be chosen to compliment the terrain you ride, hills or flats. With a new cassette you should probably replace the chain. You can use a 7, 8, or 9-speed chain with the 7-speed cassette.

Be careful to not spend more money on components than the bike is worth.

OK, you have a 7 speed cassette and a double chain ring set up.
What are the tooth counts on the ring, and the largest & smallest cogs on the cassette.
What DON'T you like about your current gearing?

Are you sure it's a cassette and not a Free Wheel? That makes a difference on what's available. Look at the link to make sure-
