Making gearin easier. Alter rear cassette or front chainring

spocky

I want to make my bike more suitable for extremely steep hills.
At present my lowest gear is 30X26.(triple with 12 to 26 rear cassette)Pretty low I know!

However I would like it to be even easier as I am doing a sportive with lots of steep hills (30% plus in places)

Is it better to add a bigger sprocket to rear cassette,say a 30 tooth?

Or is it better to changer inner ring at the front?

If adding a bigger (say 30 tooth) sprocket to rear cassette will the chain still move from 26 to 30 tooth in one step.

Any advice appreciated

If you have shimano gearing, it should be pretty easy to throw on a MTB cassette. Depending on the rear derailler you have already you may need a MTB rear derailler.

So you could in theory have a 30 at the front, and 34 at the rear.

UNFORTUNATELY IT IS cAMPAGNOLO (Veloce) WHICH i THINK RESTRICTS ME A WEE BIT

A road triple chainset generally won't accept a smaller front chainring than 30 teeth - you'd have to fit an MTB crank otherwise which will also require a new bottom bracket but you could go as low as 22 teeth. I expect you've already got a long cage rear mech having got a triple, so fitting a different cassette is your easiest option.

You can get a 13-29 Veloce Cassette.

You should be fine with the derailler, as you should already have the long cage one with a triple.

30-29 is pretty low gearing, should get you up pretty much anything.

i JUST WANT TO BUY A SINGLE SPROCKET

CHEAPER

AND MY PRESENT CASSETTE IS NEWISH.

IF I BUY A 30 OR 29 SPROCKET IT WILL MEAN A JUMP FROM 26 TO 29 OR 30.

SHOULD THIS BE OK

I'm not sure it'd work that much cheaper when you can get the whole cassette for £35.

I'm not sure where you'd get single sprockets from.

NO NEED TO SHOUT.
