Hi all
Wondered if there's a technical resource I can read regarding tandems, sizing, what makes a good touring bike etc that someone can point me towards.
I'd like to build one up, for mostly road/touring use but i could foresee some light gravel too. Disc brakes and clearance ~40mm tyres, decent luggage carrying capability etc.
In an ideal world I'd buy a used frame and make a project of it but I'm imagining they're not so common?
Any advice greatfully received!
