A bit more on this, just for fun. I had Waterford build an ST-22 that is in many ways a duplicate of the Heron Road. However, it has a lighter top tube (.7/.4/.7 vs .8/.5/.8), a lighter down tube (.65/.45/.65 vs .9/.6/.9), and lighter chain stays (30x17 oval tapering to 12.5mm, 0.8 wall, vs 22.2 round tapering to 12, probably 1.0 wall). I find the Heron to be a nicer ride. BUT, there are a couple of other critical differences. Both bikes use the Heron round blade fork crown, but the ST22 has slightly longer (bit more rake, bit more clearance) but stiffer (1.2mm vs 1.0mm wall at the tips) blades. In addition, the ST22 fork has beefy fork ends for the SON SL connectors, and a Schmidt SON hub. Also, the ST22 rides on DT TK540 rims, compared to Mavic MA2 on the Heron. Someday I'll put the Heron's wheels on the ST22 and see how that changes things; I expect it will change a lot. Don't underestimate the importance of the fork to the feel and handling of a bike.
