How we test

At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Crank Brothers Cobalt are a thin density lock-on design grips making the transition perfectly from XC trail blazer to road whippet, tourer to tagalong thanks to high quality materials uniting shock absorption and tenacious all weather grip without the chunky profiles. Death gripping the bars when screaming into winding descents wouldn't budge them but some smoother anodised/plated finishes proved trickier and the clamp bolts seemed unduly fragile

Weighing a paltry 90g and measuring a sensible 130mm wide, the composition of these grips is remarkably simple. Dual density foam sits atop a composite sleeve flanked by good looking anodised 6061 (blue, silver, gold) aluminium cuffs and a choice between standard and carbon specific end plugs. Slotting them aboard the bars couldn't be easier (although some bar/end combinations may demand a little Stanley knife surgery, thus defeating the object). Loosen the Allen screws, apply a little hairspray to the bars, slide into position and snug down very gently using a 2mm Allen key and preferably a torque wrench. I was shocked to discover the left bolt had sheared despite kid-gloves treatment but a drop of threadlock saved the day.

Ordinarily I wouldn't dream of riding any distance w gloves/mitts but as measure of their shock absorbent qualities, I set out aboard a rigid mtb for a twenty-mile medley taking in bridle path, green lane and rutted trails. Comfort wasn't quite on par with some of the really old school offerings last popular in the late 80s but they've numbed persistent trail buzz and some deeper ruts better than I'd expected from such a lightweight set. Three weeks asphalt duties confirms they're just as dependable on the open road and asphalt jungle. The dual density foam doesn't saturate come the first cloudburst, seem truly colourfast and nonchalant to everyday carelessness. However, generous width might not suit "Wiley Coyote" traffic jammers with Uber narrow cockpits.

"One of the lightest dual clamp lock-on grips for XC racing". Lend themselves very well to most flat bar applications.

A little pricy perhaps.

Tell us how the product performed overall when used for its designed purpose

Overall the Cobalts have performed very well providing excellent insulation from road and trail shock without spoiing the lines of racier road mounts. The foam seems reasonably hard wearing too, although the coming months will be quite telling.

Tell us what you particularly liked about the product

Stylish design, ease of installation and pleasing shock absorbtion.

Tell us what you particularly disliked about the product

Nothing specific aside from the delicate bolts but this may just be down to a rogue pair.

Did you enjoy using the product? Yes

Would you consider buying the product? Quite possibly

Would you recommend the product to a friend? Yes
