First Impressions: Zipp 30 Course Wheelset (Part-I)

Over the last twenty-plus years, Zipp Speed Weaponry has racked up an impressive list of firsts. From the first carbon disc wheel, to the first wheel to achieve negative drag in the wind tunnel, these accomplishments have helped Zipp-sponsored athletes become champions in the toughest races in the world. And now, with the introduction of the company’s 30 Course alloy disc-brake wheelset, Indiana’s Zipp brings a new level of performance to road, gravel, and adventure riding.

When it came time to develop the 30 Course wheelset, Zipp didn’t just slap new graphics on one of their existing designs. The 30 Course is Zipp’s first tubeless-ready wheelset (clincher models come pre-taped and include tubeless valves). To balance aerodynamics and tire support, Zipp spec’d their 30 Course wheelset with an aluminum 25 mm-wide rim (21 mm internal width) that features a 26 mm profile. The new rim boasts design innovations from the company’s 202 Firecrest wheelset–which, according to Zipp–produces low aerodynamic drag, and greater stability and predictability in crosswinds. To insure compatibility with a wide range of tire widths and pressures, the 30 Course’s rims utilizes a hook-bead design that’s suitable for use with conventional and tubeless tires.

The 30 Course’s rims aren’t the only component to benefit from trickle-down technology. Both the clincher and tubular 30 Course wheelsets roll on Zipp’s 77/177D hubs–the same ones found on the company’s pricier 202 and 303 Firecrest disc-brake wheels. For maximum versatility, the 77 and 177D hubs are easily converted from quick releases to thru-axles (12 mm and 15 mm) by swapping the hubs’ endcaps (both types are included with the wheels). Gearing-wise, the 30 Course’s rear hubs are compatible with 10- and 11-speed cassettes from Campagnolo, Shimano, and SRAM. For gravel and adventure riders, the big news is that the rear hub is also compatible with SRAM’s XD driver (available separately), enabling the use of the company’s XG 10-42 tooth, 11-speed cassettes. Freehub bodies can be swapped sans tools, and the wheel doesn’t require re-dishing afterwards.

Recently I had the opportunity to demo the Zipp 30 Course wheels at the company’s new product roll-out in San Luis Obispo, California. Zipp fitted the wheels with tires from Challenge, Panaracer, Specialized (both regular and tubeless), and I rode several 30-Course-equipped bikes on paved and un-paved terrain. With 24 spokes front and rear, I was initially concerned that the 30 Course wheelset would be too flexible for my 195 pounds. Try as I might, though, I wasn’t able to induce any rotor- or tire-rub during the initial testing. The ability to run a 10-42 tooth cassette proved especially handy during one of our mixed-terrain group rides, as the route included no less than three category-3 climbs.

Although it’s too soon to comment on the 30 Course’s durability and long-term performance, I’m looking forward to performing extended testing on Colorado’s roads and trails. The combination of tubeless-readiness, XD driver compatibility, and the wide, aero profile make the 30 Course a natural for gravel and adventure use. While the $1000 price tag isn’t exactly cheap, the ability to run both narrow and wide tires on the same disc-brake wheelset increases the 30 Course’s versatility.

First Impressions: Mio ALPHA Heart Rate Monitor

Cycling coaches and fitness experts have touted the benefits of using a heart rate monitor (HRM) for decades. And while power meters have become the hot ticket for monitoring one’s performance, wearable HRMs like Mio’s ALPHA ($169.00 MSRP) have generated new interest in heart rate-based training.

Unlike traditional HRMs, the ALPHA doesn’t rely on a chest strap to record your heart rate. Instead, an electro-optical cell senses the volume of blood under the skin, and the device uses algorithms to determine your heart’s true rhythm. The benefit? Increased comfort, and according to Mio, 99% EKG accuracy.

Thanks to the ALPHA’s simple, two-button interface, the device is easy to configure and operate. When you unbox the ALPHA, you simply set the time, and it’s ready to go. Mio recommends positioning the ALPHA snugly above the wrist bone when using the device as a HRM. During our testing, Mio’s ALPHA detected our heart rates on the first attempt the majority of the time. One criticism of strapless heart rate monitors is that they’re not as accurate as conventional strap-based devices. We compared the Mio with multiple traditional strap-type monitors, and the ALPHA’s readings were within 1-2 BPM.

By itself, the ALPHA’s reporting capabilities are limited to exercise duration, average heart rate, and time spent in the target heart rate zone. For true data nerds, the device is compatible with a wide range of smartphones and popular fitness apps including MapMyRide and Strava. Using Mio’s Bluetooth® Smart (4.0) connectivity, we were able to easily pair Mio’s ALPHA with Apple’s iPhone, the Magellan Cyclo 505 cycle computer, and Polar’s V800 sports watch.

For multi-sport use, the ALPHA is an excellent choice. The comfortable, strap-free design offers a viable alternative to traditional heart rate monitors without sacrificing accuracy. With its long battery life (8-10 hours in recording mode) and numerous connectivity options, it offers seamless integration. For dedicated cycling use where we don’t need the watch’s chronograph functionality, we would probably opt for one of Mio’s smaller units such as the FUSE or VELO.

During several months of testing, our sample ALPHA has withstood its share of abuse. From well below freezing to the mid-70s, it never failed to detect and display our testers’ heart rates. And despite an unexpected trip through the washing machine, the mineral glass LCD display remains clear and crisp. If we could make one change, we would like to see Mio develop a charger with a more mechanical connection. The current USB charger utilizes a magnetic interface, and can sometimes become disconnected from the watch (especially when connected to a desktop computer’s USB port).
