I've had an xTc since 2007 and its been brilliant for cycle camping holidays (rock solid with 25kg) and great for days out and 200km audax rides. I was contemplating an "audax" bike for longer events, probably the Thorn Audax Mk3R, but wash intrigued by this comment on page 58 of the Thorn Mega Brochure:
"In the year 2000, Fiona and I completed a very hilly 500Km Audax ride on our xTc machines. I was convinced that these lightweight 26" machines had many advantages over our 700c Audax bikes."
I'd be very pleased to hear from anyone who can expand on this comment or has experience of using an xTc on longer audax rides.
Thanks, Martin
