Hi all, I'm looking for some advice.

TLDR: bought a trek fx 7.1 last fall for a good price but I really don't like it. Trying to decide between spending money on upgrades or buying a different bike.

Last fall I got a deal on a 2015 Trek Fx 7.1 ($290) at an LBS. The problem is that I hate it. I was previously riding a single speed with a chromoly frame, but the city I live in now is way too hilly for that. I find the trek to be too heavy and slow--the rear gear is 14 instead of 11 and I find I spend most of my time in the hardest gear. Going downhill it's not easy to get good speed. The bike might also be too big for me. I'm 5'8 with a 33 instep and have a 20" frame, but have dropped the handles for a sportier feel.

I'm thinking of selling the trek and buying a new bike - giant escape 1 or 2 (probably 2). I feel dumb doing this as I should have just bought a different bike last fall. The alternative is to upgrade my trek.

So do I sink money into the Trek or buy a new bike?
