You need to weigh how much off road use you will do. I have been told that combo bikes do well at neither. The Diverge is too heavy to be a race bike and not built for true off road. I have some trails near me and was thinking of a dualsport bike until I realized I was never really going to use the off road paths, the paths were really meant for mountain bikes with some suspension and settled on a road bike (Specialized Secteur Sport) Ironically, I was looking at the Allez too but felt a more relaxed geometry would be better because I only started this Jan. and was largely a couch potatoe before. NOw, I almost wish I got the Allez. My flexibility has dramatically improved but then again I have been riding close to 5 or 6 days per week since getting the bike or , in the winter, being on a turbo trainer. Now, I no longer need the relaxed geometry but still love the Secteur and how it rides.

The only thing to ask if if you need a more comfortable ride out of the Allez if it could even take 28 tires. The brakes might not accommodate them. Also know that tires are not the most accurately measure item. Some tires are actually larger than their package indicates. I think the Michelin Pro 4 in 25 mm are actually close to 28 mm


Best of luck with your Diverge. On this thread, cycling is all about N+1 anyway. When you get your first bike, you will quickly want another one.

Welcome to the addiction.
