Indeed. But you didn't need any customer service. All they did was ship a box. Shipping company was the problem with me, due to the damage, but Cobalt Innovations have been crap after that.
When buying through Amazon, all they do is pass your returns request straight to the seller, so same thing happens. The only difference is that you can then lodge a complaint after 3 working days. Only then does Amazon get involved.
Now that my tyres, tubes and cassette have arrived, I am so tempted to just stick them on. Lol.
How are you going? Any noticeable difference? Do you use Strava? PR's all round since?
