I just bought a GT avalanche 2.0 disc. Yeah, not a 1200 dollar bike but not a super cheapo either. Its got a deore rear derailleur and an acera front derailleur. I researched its crankset, a Truvativ Isoflow from Sram and they have it listed under their "comfort bikes" section. Is this just an attempt from the manufacturer to save money on a component they might think is not as important as other components? I would figure (for what thats worth, lol) that they would build a bike with all cheap components, all mid-grade components then all high grade components. Any thoughts? Thanks, Greg
