Front sprocket for 3 1/2 Sport

[rossguzzi]

Is the stock front sprocket 14 tooth ?
Searched but cannot find it.

Yes. Standard is a 530 chain.
Your choice, but a '520' chain is a sensible option- means you can run o-ring chain.
You probably found out, but the rear sprocket standard is 38 teeth.

So if I get a 520 front sprocket, and get an o ring chain, will the rear sprocket work with them ? I have no idea what is on the rear as I dont have the bike yet.
How available are the rears ?
What do most people go with ?
Appreciate any advice..
Cheers.

Hi Ross,
If you go the '520' route, you would need a new rear sprocket as well.
For your info, the numbers for the chain refer to the pitch (distance between rivets) and width (where rollers are) in units of 1/8inch. E.g. a'530' Is a 5/8" pitch, 3/8" wide chain.

A 520, being a 14" wide chain needs the corresponding thinner sprocket.
OK, an o- ring chain technically might sap a little power, (not that I have ever noticed) but at least you can ride all day and not worry about adjustment. That's my experience anyway.
Regards,
George

Thanks George, hopefully what's on the bike is ok. Waiting for it to get here is killing me ☺
