My wife has a Specialized Sirrus Elite, 2012. It is HEAVY (almost 30lbs). She commutes 10 miles round trip and it's a lot of stop and go. She is small, and I know she struggles with how heavy the bike is (to ride, but also to carry). She has talked about getting a relaxed geometry road bike so she'll have better acceleration and be able to carry it easier. We did buy the Spec because of the resale value and could sell it easily, but I'm not convinced that is the answer. The frame is very nice (E5 Aluminum, internal cable routing, smooth welds, carbon fork, etc) and the components still have a lot of life left.
So what are some ideas for dropping weight? The Wheels are Sirrus DRX270 (dunno much about them) and we haven't been impressed. They are heavy and have not stayed true (and she is like 115lb). And the tyres are 35mm I believe, which she does not need since she only rides on reasonably well surfaced roads. So I know that the first option is to get some nice light wheels and 25mm tyres.
Components are a mix of Shimano Acera and Alivio 9spd. They are fine for what she does, but will need upgrading eventually. She'll probably ride through at least one more winter with these, but I'm just curious about what's out there since I'm only into road bike components.
She currently has a triple chainring (48, 36, ??) and 11-32 cassette in rear. She never uses the granny ring. Is it worth making any changes here? Maybe going to a double in front? What does that entail?
Finally, she is interested in getting a different set of handle bars and/or a shorter stem to give her an even more relaxed posture. Thinking that replacing w/ nice aluminum or carbon is a way to drop weight. Same w/ seat post.
Just curious as to what others have done w/ this style bike, and also what is the normal order for upgrading a bike of any kind?
