Hi Justin
Built up the tandem over the weekend and managed a short test ride this afternoon. Only 5 miles or so but first impressions are fantastic. Very comfortable on road surfaces and easy to handle.
I think we're a bit under geared as we were doing evens on the big ring into wind! I can easily change the cassette to up the gearing.
The tandem weighs in at 13.5Kg, which is everything I'd hoped for. 10 Kgs lighter than the old one!
