Earlier this yr, Giro quietly launched the third technology of the Chamber clipless mountain bike sneakers. Now referred to as the Chamber III, the most recent model builds on the EWS and World Cup-winning basis of its predecessor, with a number of updates, a lighter weight, and a notably slimmer profile. It doesn’t stray removed from the aesthetics of the Chamber II, and extra importantly, the efficiency that made that shoe a go-to choose for a lot of aggressive downhill, enduro, and path riders and racers.
I’ve been testing the brand new Chamber III sneakers for the reason that starting of the summer time. I’ve been switching out between these sneakers, the Experience Ideas Hellion Clip BOA, and the Crankbrothers Mallet Path BOA on nearly each mountain bike journey I’ve been on for the previous 4 months. Whereas it isn’t a wild departure from the earlier model, Giro made quite a few adjustments and updates that I really feel make it higher than its predecessor.

Giro Chamber III Particulars
Earlier than I’m going into my assessment of the Chamber III sneakers, let’s take a fast take a look at the specs, options, and particulars. First, the Chamber III is Giro’s top-tier gravity-oriented clipless mountain bike shoe. Extra precisely, it’s really the one gravity-oriented clipless shoe within the model’s lineup. It replaces the much-loved Chamber II, which had been raced to quite a few EWS victories on the toes of Richie Impolite and others — and I examined waaayyyyy again in 2018.
The Chamber III maintains roughly the identical silhouette and general type because the Chamber II, nevertheless it seems to be and feels prefer it has been placed on a food regimen. Giro slimmed the shoe down by eradicating many of the pillowy cushioning all through the uppers and the tongue. The brand new “low-bulk tongue” absolutely wraps over the foot and is stretchy with a a lot decrease quantity than the outgoing mannequin, but nonetheless supplies a little bit of cushion for the highest of the foot. Weight has additionally come down a bit, with the 43.5 that I’m testing at 481 grams/shoe, versus the 525 grams/shoe (measurement 44) of the earlier model.


The microfiber uppers are largely seamless aside from the overlays stitched on either side for the Velcro Powerstrap and one seam down the heel. Giro’s RockPrint reinforcement wraps all the way in which across the toe field so as to add a bit additional safety and sturdiness for the high-wear space. Air flow options embrace perforations above the toes and on either side of the midfoot, together with a breathable development of the stretchy, low-bulk tongue. The closure consists of conventional laces together with a Velcro Powerstrap up on the high.
Underfoot, Giro has integrated a “customized DH shank with +10mm of cleat setback.” That is supposed to permit riders to place their cleats farther again than on the model’s different clipless sneakers. Giro additionally states that this DH shank strikes the proper steadiness of stiffness and walkability. Aside from the cleat field, the only real is absolutely coated in Giro’s Sensor rubber with its gamma tread sample. Whereas it seems to be comparable, this rubber compound is kind of a bit firmer than the Tack rubber used on Giro’s Latch flat pedal sneakers.
Match and Consolation


When the Chamber III got here out, I used to be completely satisfied to see that Giro added some half sizes to the dimensions run. I put on a 43.5, and was pressured to measurement up or down within the earlier model. With the brand new sneakers, I get a extra exact match straight out of the field. As such, I discovered the size to be spot on for my toes. In any other case, the match strikes me as practically equivalent to the Chamber II. Each the width and quantity really feel like they’re on the roomier facet of common. I’ve very common toes that work in most sneakers, and whereas these aren’t the snuggest becoming, I discovered it straightforward to get them tight sufficient for my wants.
Laces are slowly however absolutely being overtaken by BOA closures, however they nonetheless work nice, even when they’re a bit slower to placed on and take off the toes. I had no points getting these sneakers tight sufficient with the laces, and the Powerstrap actually labored properly to lock my heel down. I believe an elastic lace retainer could be good, nevertheless it’s straightforward sufficient to pin the laces down below the strap as properly. The footbed is comparatively skinny and primary, nevertheless it’s properly contoured and comparatively comfy. That mentioned, these with particular assist calls for will probably wish to improve to an aftermarket choice.
On the Path


I believe Giro nailed the candy spot of pedaling effectivity and assist with the earlier model of this shoe, and the Chamber III feels practically equivalent on the path. For a way they give the impression of being, these sneakers are surprisingly stiff underfoot, and there’s no noticeable flex below pedaling energy. Once you get on the gasoline out of a nook otherwise you’re grinding up an extended climb, it positively seems like all of your effort goes straight into the drivetrain. Fortunately, they aren’t carbon-sole stiff, so that they don’t punish your toes on lengthy and tough descents — there’s simply sufficient forgiveness and cushioning within the midsole.
The soles are additionally torsionally stiff, offering wonderful lateral assist, particularly when paired with supportive pedals. I rode these with the new OneUp Clip pedals in addition to the Shimano XT Path pedals, and the soles had a really optimistic interface with each. Actually, the cleat field is a tad deeper than a few of my different sneakers, so I added a small shim below my SPD cleats to make clipping out and in simpler than it was initially. That cleat mount space is kind of lengthy with sloped main and trailing edges and loads of room to slam cleats approach again if that’s your desire.


With a bit rocker within the sole from the cleat field ahead and decently grippy rubber soles, the Chamber III is simple sufficient to stroll round in. There’s a little flex within the toe, however not fairly as a lot because the earlier model, and these sneakers really feel a bit blocky when strolling. They really feel just like the Fox Union BOA, for instance, while you’re pressured to hike-a-bike. Which is to say they work simply wonderful, however there are higher choices if journey using is your factor. These sneakers are made for using bikes and shouldn’t be confused with a biking and mountaineering crossover-type shoe.
The microfiber uppers have a troublesome, sturdy really feel to them, they usually have shrugged off the entire abuse that I’ve given them up to now. The white colour of my take a look at pair will get soiled, after all, however they clear up comparatively properly with a wipe from a humid material. Fortunately, additionally they are available in black. Whereas there are fewer air flow holes than the earlier model, it looks as if the diminished bulk of the uppers has prevented them from being too sizzling on my toes. They aren’t super-breezy by any means, however the thinner and extra air-permeable tongue permits noticeably extra air to move via it.
For the overwhelming majority of my using, my toes really feel properly protected within the Chamber III. The strengthened toebox and stiff heel cup simply fend off many of the threats to my toes. That mentioned, the general degree of safety appears a wee bit lower than some comparable sneakers with thicker, more durable toe bumpers or prolonged medial ankle safety.


Giro Chamber III: My Takeaway
It’s been seven years since Giro up to date its clipless gravity sneakers as a result of the second model was fairly darn good. The Chamber III carries that torch and runs with it, with quite a few updates and enhancements that construct on that legacy. With comparable on-bike efficiency, barely lighter weight, much less bulk, and extra sizes to select from, the brand new Giro Chamber is the very best its ever been.
At $200, the Chamber III can be the costliest it has ever been, however that’s not too shocking given the rising price of nearly the whole lot bike-related — and the whole lot else, for that matter. Nonetheless, they’re cheaper than most comparable sneakers geared up with BOA closures, and aggressive with different burly, high-performance lace-up clipless sneakers.
In the event you appreciated the Chamber II, then I can nearly assure you’ll just like the third iteration. It’s nearly the identical factor, just a bit bit higher. In any other case, I believe it’s a stable choice for any aggressive riders searching for a shoe that’s comfy, environment friendly, sturdy, and doesn’t have BOA. Examine them out on the Giro web site or your native Giro retailer.
