I don’t really ride a lot, but I plan to ride more. Last year I lost 60lbs and started commuting to work by bike (15km each way). I stopped commuting in the fall when it was getting colder and darker and plan to pick it back up in the spring. I don’t have a lot of time to train so I do a lot of trainer rides and use my commute. But I did a 100km ride last year (25km/hr average) and felt pretty after. 2000kms for the year total approx (Including trainer miles).

I don’t see myself racing or doing any major club rides this year but if the training goes well I don’t see it out of the question in the future.

My made up budget is around $1000 - $1500 (Canadian). It seems that if I push the budget I can find bikes with 105 sets, but then I'd still have to get pedals etc. Would I be disappointed with Tiagra? Seems like in most cases its the same frame with different parts, so you could upgrade but I tried that with my Mountain Bike and although I'm happy with it now I know I spent more then I needed to and was always thinking about what to change next.

Any advise on what bike to look for? I'm currently looking at the CAAD9 5, CAAD9 6, Felt F75, Felt F85
