Hello everyone

I’m currently riding a 2009 Sirrus Elite hybrid and was wondering if an upgrade in tires & rims would give me the performance boost I’m looking for. I feel as if I’ve outgrown my hybrid. I ride about 120 miles per week on city streets. I’m not a racer, but would like to ride more efficiently.

The LBS said I would need to spend approx. $1200 for a road bike that performed as well as my ‘09 Sirrus Elite. Or that I should consider better rims and thinner tires (23c or 25c) for the hybrid which would run around $400. I think I would rather invest said amount towards a new road bike.

My main concern is whether I’ll be comfortable on a road bike. Although I’m very flexible, I still experienced neck & upper back pain until the handlebars were adjusted for a more upright position on the hybrid. I also have neck and back pain in general, as well as a torn rotator cuff. Given these challenges, should I still consider a road bike? Perhaps one with less aggressive geometry?

My road bike choices would be limited as I'm 5’1.5”, and presumably would need a size 46/47.

Should I just upgrade the tires & rims on my hybrid, or get a road bike instead?

Many thanks in advance for your suggestions.
