BB and Chainset replacement

Hi guys

I have a friend who has worn chainrings and a bottom bracket that needs replacing.

Currently he has a SRAM VIA Centro power spline, 48/32T chainset and a
SRAM, PG-1030, 10-SPD, 11-36T

Bottom bracket is a Truvativ 68x118 powerspline.

He said he only uses the 48t ring. He does not use the 32t. It’s a Boardman Hybrid bike.

He has a 10 mile exercise route he does on a daily basis. Nice flat tarmac cycle route.

Ideally if he could lose the 32t and go for a single that would suit him better.

If he has to stick to a double he doesn’t mind.

What are his options in replacing the chainset and bottom bracket.

From reading square taper seems to be the most reliable.

Any recommendations?

Hold my beer and watch this....
I think in his position I would reassess the ratios completely.
Front would stick with a double but go to something like a 36/52 and at the back change the cassette to something like an 11-26 to give a closer set of ratios while still keeping the small chainring for when the gradients increase.

He could go with either a square taper BB like the good old Shimano type or a more up to date one like Hollowtech which has outboard bearings and is lighter. ST will be cheaper and longer lasting.

Thanks guys.

I dont even know what to look for in regards to a square taper 36/52?

I understand it will have to be a road chainset?

I did some reading on various forums and the general consensus was its a headache putting a road chainset on a mountain bike.

I take it this is where the Hybrid bike differs as it already came with a road chainset?

I would rather stick with square taper for him.
