Interesting thread. I hope that tomorrow will see the delivery of my new Spa Steel Audax, specced with the Shimano 105 build and leather ti railed Spa saddle. Having been a very happy owner of a Thorn Audax [see my posts passim] before, I regretted the day I sold it ever since and it was a toss up between another Thorn or the Spa. I happened to be in North Yorks a couple of weeks ago and so, when I eventually found the Spa HQ [cunningly hidden away!!!] I had time to test one out for size. They have every size built up as demonstrators, and are happy to let you ride/test/sit on the bike to ensure sizing is correct.
The key thing that swung it for me was the size - I had a 570 frame on the Thorn and it always seemed tantalizingly on the small side for me, whilst being lovely at the same time. The Spa comes in 58cm and just sitting astride it was a revelation - it felt right straight away. I don't tour or carry any excess weight so I think this bike seems to be fairly close to the 'old school racer' ethos which is what I want.
I went for the Rigida handbuilt wheels option, as I had a pair of Spa built Rigidas on my Thorn Audax and they were unbreakable. Oddly, carbon forks are standard and steel are an extra, whereas I seem to remember it being the converse at Thorn?
I will report once I have had a chance to ride the bike, which weather permitting will be later this week, tho' it will probably now snow for the next six weeks just to spite me. I hope I will still be allowed to post on the Thorn forum!!!
