Bike 1: Trek Domane
Bike 2: Specialized Allez Sport
Both are 54cm, and appear to be in decent condition
I am a 5’7.5”-5’8” male with a 32” inseam.
I feel like I'm kind of in between sizes depending on the bike. I've heard that if you're between sizes, it's usually better to go smaller since it's easier to make a smaller bike fit than a larger one. But I also don't want to end up on a bike that's too small.
I’m leaning towards the Trek, but again, I’m not sure if 54cm is the right size.
Which size would you recommend for me, and which of these two bikes would you choose?
Is there anything specific about the geometry of a Domane vs. Allez sport that I should consider for someone my size?
Are there any red flags I should look for in either bike before buying?
