Rohloff SPEEDHUB & Gates Carbon Drive

As the North American service center for Rohloff’s SPEEDHUB 500/14 internal gear hub, we periodically field questions from customers concerned about noises coming from their SPEEDHUB. These noises are described in a variety of forms—squeaks, creaks, clicking, ticking, popping, clunking, thunking—and customers are often convinced the hub is the source of their noise woes.

In 2016, Rohloff introduced a new version of their renowned SPEEDHUB 500/14 14-speed internal gear hub that works with through axle frames. Dubbed the SPEEDHUB A12, Rohloff offers versions to fit frames with 12x142, 12x148, 12x177, and 12x197mm spacing. The SPEEDHUB A12 is nearly identical to the standard Rohloff SPEEDHUB 500/14, with the exception of how the hub connects to the frame.

New Rohloff users often find themselves wondering which size front or rear sprockets to use with a SPEEDHUB 500/14 or how to compare different Rohloff gearing setups with a derailleur bike. Rohloff gearing can be easily compared to external gearing using the internal gear ratios for the SPEEDHUB and the size of the front and rear sprockets.

We assembled this striking commuter bike for a local customer named Paul, who runs a bike fitting business called Fits by Paul in Marin County. He is an accomplished road rider and works with his customers to fine tune the fit of their road bikes for comfort and to prevent injuries while riding. For the times when he’s not riding his road bike, he wanted something more casual that was also trouble-free for riding around town.

This Merlin Roots came in to the Monkey Lab for routine service, and we were excited to check it out. Offered as a limited edition, the frame is modeled after the original west coast "Klunkers," the home-made dirt cruiser bikes that were ridden at breakneck speeds by the pioneers of mountain biking on the dirt roads and hiking trails of Marin County's Mount Tamalpais.

Bamboo is an unconventional material to build a bike from, but it has become an increasingly popular option as more and more riders discover the unique ride quality that it offers. We built this bamboo Calfee Design frame for a customer who enjoys long organized rides like the Seattle to Portland event along with exploring back roads around his home near Seattle. He also planned to use the bike for his daily transportation needs, so it was designed as a sturdy road bike/light duty touring bike.

Riding the Divide is one of the most awe-inspiring and grueling cycling challenges in the world. The 2,700 mile, 200,000 foot elevation gain ride goes from Banff, Canada to Antelope Wells, New Mexico, traversing the whole length of the United States along the Continental Divide. The Divide is also the route of the annual Tour Divide, a famous unsupported endurance race.
