what is the spoke size of the trek, alpha 1.5,

I've only encountered one minor issue, the stock hubs have a rubber boot which can squeal some if not kept lubricated - however the stock wheels are a prime candidate for upgrade as they are relatively heavy compared to others in the Bontrager lineup. The Tiagra thumb shifters are not reachable from the drop position, though the brake shifter is.

Great value for the money. This bike is a joy to ride with surprising acceleration. The frame is solid and a great foundation to build on when you're ready to upgrade. This is a terrific first road bike and gives you a taste of what to expect from bikes which cost much more.
