Giant-Alpecin have been spotted at the Criterium du Dauphiné riding a new version of Giant’s flagship TCR Advanced SL.

According to the list of approved frames published by the UCI, Giant applied for approval for two new models of the TCR Advanced towards the end of March. The top model looks to be the TCR Advanced SL ISP – which we take to stand for integrated seatpost.

The new bike has been spotted being ridden by the Giant-Alpecin team at the Criterium du Dauphiné. Unlike the new Trek Madone which we covered yesterday, the new TCR Advanced SL seems to be a development of the current model rather than a radical makeover.

The tube profiles appear to have evolved, with the most pronounced change being in the head tube junction to the top tube and down tube, where the profile seems to have been strengthened, presumably for increased rigidity.

The seatmast design also seems to have changed from the current model, as has the junction from the seatstays to the seat tube.

As usual pre-launch details are scant – we’ll post an update once we know more. We reviewed the current model of the TCR Advanced SL in March 2015 and were impressed with the performance, although we found the ride a little harsh, so we’ll be interested to see how the new model has evolved.
