Wasting no time since the bike’s initial release last fall, Ventana has rolled out a new option for the Wolfram 27+. Alongside the standard Wolfram (which is hardly standard with a belt drive Rohloff option), the new version adds in a gearbox. Specifically the Pinion P1.12, though P1.9 and P1.18 gearboxes will be available on request. Built around a 120mm fork and with provisions for belt drive and the Pinion gearbox, this is one interesting option for 27+…
Shown at Sea Otter with the Pinion P1.9cr gearbox, as mentioned the frames will ship complete with the P1.12 which offers 12 gears and a 600% overall ratio. Gearboxes come equipped with Pinion’s crankset and their own sprocket for use with the Gates belt drive system. The rear dropout is split at the seatstay/chainstay junction and builds in a chain tensioner on both sides for belt tensioning.
Like other Ventanas, the Wolfram 27+ Pinion is made in the U.S. from butted and hydroformed aluminum tubing. The bike’s geometry is designed around a 120-140mm travel fork, with the tapered head tube set at 67 degrees (with a 120mm fork) and the frame runs 419mm chain stays in the shortest setting thanks to the machined chain stay yoke.
In total there will be versions built for the Rohloff including the 10×135 hub or their 12 x 142 Speedhub A12, and a derailleur bike with 148 x 12mm Boost spacing. The Pinion and Rohloff versions will be sold through Cycle Monkey with pricing starting at $6500 for a complete Pinion model or $6040 for the Rohloff.
