Re:
Look at Spa Cycles website (
http://www.spacycles.co.uk/ ), good value and interesting gear for touring. Visit CTC forum (
http://forum.cyclinguk.org/ ) for some interesting and quirky observations about cycling, bikes and touring. If it’s a special project why not go custom built, especially if it’s your retirement gift to yourself? Loads of decent framebuilders around these days. Mercian has a certain cachet, same with Bob Jacksons, but choose whatever you want and the features you want for the kind of touring you want to do.
I tour on two bikes these days: one, Dolan Dedacciai from early 2000s, has braze ons for pannier rack, obviously steel, triple and not particularly light (11.2 kg). But, incredibly strong and resilient, stable on descents, at speed and loaded (eg coming down Col de la Bonnette or Alpe d’Huez), because has long wheel base. My ‘go to’ bike for heavier weight and rougher terrain, not a lot I wouldn’t do on it (I do use decent touring wheels from Spa Cycles). The second is a Bob Jackson, 731os from 1992, and I fix rack on with P clips, triple and fairly light (10 kg but use Brooks saddle): this is fast and comfortable for all day rides and equally stable on descents (44 mph going down Terrington Bank trying to keep up with one of my sons, not a hint of wobble). I use this bike for steep days out in the Yorkshire Dales or long, lightweight tours, eg a double end to end last year and quick North Coast 500 this year, comfortable, fast, the business. But, neither bike designed for touring.
If I had the means I would get a custom build following a decent bike fitting. As light as I can get away with. I’m fine with rim brakes but discs do have an appeal for touring. Would want fittings for rear rack only (I’m lightweight tourist). Some very light racks out there, Tubus amongst the best but pricey. An advantage to be able to fit fairly wide tyres – more comfort on longer distances. Many tourists like mudguards. If it’s your retirement gift to yourself then choice of groupset is, presumably, entirely up to you – this sounds a very enjoyable time for you!
