Comments on frame please before I pull trigger

GVH has a 62cm Jeff Lyon touring frame on their site that I have been eyeing for some time now. They have had it for a good while - well over a year. Here are the frame specs:

ST = 62 c-c
TT = 59
HT = 19.7
SA = 73
HA = 73.5
CS = 44
Reynolds 725
Long reach brakes
wishbone stay

Well I would have wished for another cm or so on the top tube but, the 59 is workable. I would have also preferred normal seat stays but, again the wishbone is not the end of the world. The thing that bothers me the most is the 73.5 HA. Now I realize that the trail figure is a function of both HA and fork rake. However, I would like to know if anyone of you see a potential problem with this being that virtually every bike that I have looked into seem to have a more relaxed head angle. Will this be problematic for front panniers should I decide to mount a pair? Mounting of lights? I will probably opt for the Schmidt hub/Lumitec system.

Also, I don't see a potential issue with the wishbone stay however, if any of your think there could be one then I am all ears.

Other than that, I believe $700 for a fillet brazed 725 frame is not a bad price. And GVH seems to offer a competitive build package too.

The numbers do not yell touring frame to me. It seems like a frame built custom for someone with a short torso, who didn't buy it.

Odly the head angle doesn't look all that steep, but I didn't try to measure it. I like the bike to stear itself straight on long days on the road. If you are riding roads, there is rarely any need to have jumpy stearing as one might want in the peleton.

I have a mountain bike with wishbone seat stays, and I never noticed anything adverse about it, as long as you can get your fenders on there.

I wouldn't buy a custom cast-off just because it would be a good deal due to materials and workmanship, if only it fit.

Well, I don't know what numbers Peterpan is looking at but that certainly looks like Touring geometry to me.

My Basso Loto (62 cm) has a head angle of 74 degrees and people always told me that it would be squirelly. In fact it is the steadiest bike I have. So I wouldn't worry about 73.5.

The fact is that I would expect a 62 Touring bike to have a 57 cm top tube. With a 59 you'll have to use a short stem in order to get the more upright posture of a touring setup. That's probably better anyway since it gives the steering a more solid feel. Those are the sort of selections a frame builder like Lyon makes using his experience and that of others who have used his products.

GVH is and always has been a very competent and honest company to do business with. I doubt that anything has changed with the death of Gary Hobbs. I recommend them as I have for several years.

The geometry may be relaxed enough, but the chainstays/rear triangle looks a little tight. This may give you issues with heel strike and also has less road-smoothing effects you'd get from a longer wheelbase.
