if you are looking at the TCR I’d recommend waiting to try the 2016 model, it was really night and day different when I rode it, compared to the older bikes.
Felt less bulky, less “neutral” so much more ‘lively’ in a good way. Felt more like my Tarmac SL4 in terms of handling, which is a compliment.
I liked the previous TCR as I spent a month riding the Advanced Pro above; however it felt very ‘workmanlike’ and efficient rather than being an exciting ride like the new TCR
Comparing 2015 TCR to Propel, I really preferred the balanced ride feel of the Propel, which surprised me as I had not enjoyed previous aero bikes I’d ridden. The Propel had excellent handling and feel across the entire frame.
