Until recently, riders seeking cassettes larger than 36 teeth had two options: aftermarket extender cogs or SRAM’s XD-based freehub/cassette system. Now, there’s a third option with SunRace‘s line of wide-range cassettes. The company’s cassettes fit standard Hyperglide-compatible freehubs, and are available in 10- and 11-speed versions.
My first exposure to SunRace‘s wide-range cassette coincided with the arrival of a Gestalt 2 demo bike from Marin. The aluminum-framed Beyond Road model featured an 11-42t SunRace cassette paired with SRAM’s X7 MTB rear derailleur controlled by Apex DoubleTap levers. That combination performed so well that I was inspired to install a SunRace wide-range cassette on one of my personal bikes.
SunRace offers their wide-range 10- and 11-speed cassettes in two versions: the all-steel CSMS3, and the CSMX3 which features an alloy 40t or 42t cog. The aluminum large cog saves approximately 60 grams, with my sample 11-42t MX3 cassette weighing 389 grams (two grams over the claimed 387-gram weight). SunRace doesn’t specify a retail price for the MX3 cassette, but they can usually be found online for less than $70.
If you work on bicycles and you’ve ever used a grease gun, there’s a good chance it was made by DUALCO. The Texas-based company has been producing professional lubrication products since 1960, and recently introduced their line of bicycle lubes. DUALCO’s bicycle products include extreme-duty and high-performance greases, cable lube, and spot oil.
Not so long ago, there weren’t many choices for GPS-enabled cycle computers. In the past couple of years, however, more companies have thrown their cycling caps into the bicycle GPS arena. One of the companies looking to capture a piece of that pie is Magellan, a 30-year-old company which boasts more than 200 GPS-related patents.

Designed for road, mountain, touring, and training, the Cyclo 505 is the company’s flagship cycling computer. Magellan offers the 505 in two flavors: the basic head unit ($379.99), and the HC bundle which includes heart-rate and speed/cadence sensors ($449.99). Both versions include out-front and pad-style handlebar mounts, and come preloaded with detailed road base maps and OpenStreetMap (OSM) crowd-sourced maps.
Rolf Wheels got its start back in 1997 when founder Rolf Dietrich partnered with Trek to bring paired-spoke wheels to market. After the license agreement expired in 2001, Dietrich founded Rolf Prima Wheel Systems with three former Trek/Bontrager product engineers. One of those former Trek/Bontrager employees, Brian Roddy, would eventually become Rolf Prima’s owner. I spoke with Roddy at this year’s Interbike trade show, where we discussed Rolf’s wheels, gravel and adventure riding, and what the company has in store for 2016.
GRAVELBIKE: Do you think that disc-equipped gravel and adventure bikes will standardize on 142mm rear spacing?
Rolf Prima: We hand-build everything pretty much to order, so we build fronts as 9 mm, 12 mm, or 15 mm, and rears as 135 mm or 142 mm no problem. That said, the industry will probably coalesce around 12 mm thru-axles front, and 142 mm rear. I think everyone–the industry and customers, alike–really wants the proliferation of standards to slow down and stick so they know that their expensive bikes and components will be replaceable, serviceable, or upgradeable in a few years (instead of becoming obsolete).
