The big news from Gaulzetti, which he alluded to in the pre-show interview, is the introduction of steel frames using Columbus’ über-oversized PegoRichie tubing.
Frame weight can be as little as 60g heavier than their aluminum frames. Builder Craig Gualzetti says its their first tubeset he’s used that’s not of his own design because he simply couldn’t make something better. They’re one of the first builders to use these tubes, and the stealth black road bike above is the result.
Check some raw frames of this and his traditional aluminum road bikes, along with Di2 bikes from Dave Wages at Ellis Cycles, after the break…
And here’s what it looks like before it’s painted:
By comparison, here’s how fat the welds on aluminum tubes are:
Craig said typical alloy frame weights are 1150g depending on size, and complete bikes are already easily built under UCI minimum weights.
ELLIS CYCLES
Ellis Cycles’ builder showed off his Dave’s DRB (Dirt Road Bike) with Di2 shifting, full fenders and plenty more that made it a touring bike to dream about.
Long pull brakes allow full size fenders and are run through a classy little brake arch that’s mimicked by the seatstay bridge just above the fender.
Di2 wiring runs through small clips to keep it tidy.
Only the head tube and fork crown lugs are painted, the rest are polished to match the tubing and S&S couplers.
Triathlon bikes aren’t too common at NAHBS, but Ellis’ Makenzie’s Tri Bike was also decked out with Di2 wiring run through the HED Corsair aero bars. Wiring is internal through the True Temper and Columbus tubed frame. Paint by Sanchez Paintshop.
His touring bike was very upright and classic looking and had a pretty trick feature I’d not seen before: The front bag’s upper stabilizer bar was bolted in through the handlebar clamp bolt on the stem.
