Hi guys,

I'm a long time, born again, cyclist but I've only ever ridden stock wheels that came with my bike.

I got a new bike this year - Giant TCR Advanced 2. My first carbon frame and I'm loving it.

I can't afford $2,000+ for big name carbon rims. It also doesn't feel right putting on wheels that are more expensive than the bike.

Through my club I can get a great discount on a set of Rol Race SL. All the reviews seem very positive but maybe a little out dated. They are claiming an aero advantage for a 30mm rim but I can't imagine it being significant...

I think I would lower the weight of my bike by 350-400g

I live in Korea so we have a lot of climbing and descending here. I do group rides. I ride sportives. I might get involved in racing if I continue to improve and am not too old

What are your thoughts on a wheelset upgrade? Is it worthwhile? Will I notice significant improvements and benefits?

Thanks in advance.
