When I first began this upgrade quest I was focused on the Speed Pro TT as there was a like new one avail in my area and I’d read good things about the bike. Wasn’t looking at 451 wheels at all. Then I read about parts avail issues on that bike. I spoke to my LBS mechanic, who’s opinion I value, and he said stay away from that bike and have a look at the Verge series with the 451’s.
I take all the input gratefully and seriously and eventually form my opinion. I’m extremely analytical (unfortunately).
I might stand pat for a bit, adjust my budget (upwards of course) and look at better bikes.
