11spd: This week's best new bike gear

Elliptical MTB chainrings, ultralight Giro road shoes and more

Huzzah! It's Friday, at last! And what a week it has been here at your online emporium of bike information that is BikeRadar.

We've been fist-fighting with Bouhanni, seen new alloy Treks with the IsoSpeed Decoupler, taken a peek at some pro-level shoes, ridden a new suspension fork with a whopping 40mm of travel, learned how to clean bikes and had a gander at Tom's long-term Transition Scout. He's a lucky boy... Now it's time take a gander at the latest goodies to show up in BikeRadar's Colorado offices.

Wolf Tooth PowerTrac elliptical chainring

In addition to making upgrade cogs and outstanding dropper seatpost levers, Wolf Tooth also makes narrow/wide chainrings.

The PowerTrac elliptical chainring features Wolf Tooth’s narrow/wide tooth profile and is constructed from 7075 aluminum.

According to Wolf Tooth, the PowerTrac chainrings are slightly less ovalized than many competing products, but with a more aggressive 112-degree timing. The company claims this results in a less noticeable change in pedal stroke with the same consistent power benefits that come from elliptical chainrings.

Wolf Tooth offers PowerTrac chainrings in direct mount versions for SRAM and Race Face Cinch, and all common bolt circle diameters.

We’re testing a 34t Race Face direct mount ring.

Dakine Anthem knee pads

The new Anthem knee pads take cues from Dakine’s Hellion and Slayer knee pads and add some easy on, easy off, tech.

Velcro straps allow riders to easily put on the Anthems for rowdy descents or remove them for the climbs without removing shoes. Silicone grippers keep the pads firmly in place.

The molded CE-certified impact foam is pre-curved for an ergonomic fit and an anti-microbial Polygiene treatment keeps them from getting too funky.

OttoLock

The OttoLock may look like an overbuilt zip-tie, but under its rubberized exterior are multiple layers of steel and Kevlar bands.

At 235g, it’s lighter and more compact than a U-lock. OttoLock claims this 18mm-wide band is more secure than cable locks. Like cable locks, the OttoLock is positioned to deter opportunists in low-theft areas.

The 60in / 152mm version wraps up small when not in use

The OttoLock is available in 46, 76 and 152cm versions. Shown here is the 152mm version.

  • Price: £60 / $75 / AU$98

If you don’t like keys, but want a lock with more robust protection, there’s the new RockyMounts Shackleton.

This U-lock has a 12mm steel shackle that measures 95mm wide by 170mm long.

The four-digit code can be personalized and the easy release button frees both sides of the shackle for quick and easy installation and removal.

  • Price: £28 / $35 / AU$48

Giro Prolight Techlace

On the heels (ahem) of Giro's Factor Techlace with one boa dial and two Velcro/lace closures comes the Prolight Techlace with, yes, three Velcro/lace closures. 

Giro is touting this show as sub-150g (in a size 42.5). Our test pair of size 45 weighs 187g for each shoe. Regardless, they are indeed quite light.

We already have a few hundred miles on these and will have a review up next week.

Race One bottles

Race One is an Italian brand with a variety of somewhat unique products. For instance, the OneTouch bottle (center) features a spring-loaded valve for opening and closing. Instead of pulling open and pushing closed a rubber valve with your teeth or hands, the OneTouch can be opened and closed with a single finger by pressing once on the top.

Race One has debris covers for its bottles, which may be appreciated by those who ride farm roads and/or in the rain.

If bite valves bug you, then check out the spring-loaded tops from Race One

Finally, the PR.1 Box is a two-tiered tool storage container. The black top screws off to access a small container, and the red portion opens to allow access to the main compartment where you can stow a spare tube, a CO2 cartridge, a tire lever and more.

Schwalbe Tire Booster

Schwalbe's Tire Booster lets you use a standard track pump to seat tubeless tires
Schwalbe's Tire Booster lets you use a standard track pump to seat tubeless tires

Want to set up tubeless tires but don't want to spring for an air compressor? There are products like the Bontrager Flash Charger, which combines a pump and a secondary chamber that you pressurize, and now, if you already have a floor pump, there are chambers like the Tire Booster you can use.

The Tire Booster is Schwalbe's licensed version of a product by British company Airshot. You pump it up, then connect it to a tubeless valve, flip open the valve and boom — your tubeless tire is seated. 

You pump up to the Booster via the Presta valve on top with the light blue lever closed. Once it is pressurized, you screw the valve onto your valve stem, then open the blue lever to release a big blast of air

Castelli has a huge range of clothing, from the straightforward to the eccentric. Two new pieces for this summer are the Climber's Jersey 2.0 and the Inferno bib short.

The Climber's 2.0 features thin breathable mesh, but with longer sleeves that actually stay in place and pockets that actually hold some cargo without sagging comically. This wasn't always the case with Castelli's ultra-light tops.

The Inferno bib short uses the Italian brand's Kiss chamois but in a light bib with perforated legs and mesh compression bands. You'll need sunscreen on your thighs with these shorts.

  • Climber's 2.0: £80 / $129
  • Inferno: £125 / $229
