When the mood hits, ride with it.

With the advent and popularity of the 27.5 platform, the 29er is no longer that standout it used to be — that is, until Pivot introduced its LES 29 Carbon Mountain Bike Frame. Pivot uses the same carbon molding technology that it used on its Mach 5.7 frame, the benchmark for carbon frame design. It is an exclusive hollow-box, high-compression internal molding technology. The frame went through extensive computer analysis, which creates Pivot’s curves. And those curves aren’t just eye candy. They create a sub-2.5lb frame with stiffness for fast acceleration and compliance to reduce chatter. Using an internal mold, the carbon receives maximum compression to create a lighter and stronger frame. Unused resin is removed and carbon is reduced in areas where it isn’t needed. As far as the shaping of the tubes, while LES receives an oversized down tube, the top tube and seatstays are flattened. This allows for the motion to dampen the ride. Giving the LES extra spring are the short chainstays and the 92mm PressFit bottom bracket. And while these additions are perfect for a geared bike, the LES is also very capable in the singlespeed market and is easily convertible with Swinger drops, sold separately. Pivot's Swinger adjustable design swings around a pivot that's located in front of the upper post mount of the brake. The arc allows tensioning of the chain with very little effect to the LES’s geometry.

The geometry is designed to be active and responsive, with 17.1 inch chainstays and a 69.5 degree head tube for a more slack position than a traditional XC race bike. It is tapered and Pivot recommends a 100 to 120mm fork. It uses a 30.9mm seatpost, direct-mount front derailleur, and a 12x142mm rear axle, which is included.

  • Carbon fiber hollow-box, high compression frame
  • 12x142 rear axle
  • Designed for use with a 100 to 120mm fork

Unique race Machine

  • Familiarity: I've put it through the wringer

Pivot took a unique path when creating this. Most companies tend to have very aggressive steep head angles on their XC race bikes because this ensures a quick handling bike (Ex: Specialized, Felt = HA 71 Pivot HA 69.5). But Pivot managed to managed to make their 69.5 degree head angle hardtail into the perfect race bike. Short chainstays make the bike corner like a dream in tight corners and switchbacks despite the slack head angle.

Having such a slack head angle has plenty of upsides, like charging downhills. I found that the Les 29er handles high speed downhills better than any other XC race bike I've ridden to date. It also handles rough stuff better than most. Specifically, charging into rough stuff. I've been able to charge into gnarly rock gardens with more confidence than on my previous bike.

The only downside in my opinion is the weight. It's by no means a heavy bike, but it also isn't very competitive with light weight hardtails. I think this is because of the removeable/ replaceable dropouts. Had pivot went with a standard dropout this frame would have been a good deal lighter.

All in all a great bike though.

Top of the Line

  • Familiarity: I've put it through the wringer

I had never tried a Hardtail with a slack (69 Degree) head tube angle. I had always used steeper setups and so I was concerned about how tight it would feel. However all my concerns have disappeared. Putting the front wheel out just a little farther makes this bike go downhill like any full suspension xc bike. The rollover is incredible. It doesn't feel like a long bike in the corners though, the super short chain stays keep it feeling nimble. On the climbs it is stiff enough to feel that all your power is keeping the bike going forward and not flexing the frame. Long story short this bike rips.

Cream of the Crop

  • Familiarity: I've put it through the wringer

This is probably the best hard tail on the market. With the slacker head tube angle you are not forced into a race oriented cockpit, but a more relaxed geometry which provides additional confidence on the more technical descents. The Swinger Dropout systems that allows for single speed conversion really underscores the bike's versatility. From 100mi races to moonlight Wasatch Crest rides, I couldn't be more satisfied with the Les.

Hands hardtail frame ever

  • Familiarity: I've used it several times

I have purchased and built-up three frames from CC the last 12 months...jet9 rdo, Air9 carbon, and now my Pivot Les....this is hands down the best hardtail I have ever ridden. The frame finish is amazing and every detail has been accounted for. Laterally stiff and vertically compliant! It has more of a slacker feel than other hard tails I have ridden, yet still handles like a XC race machine....the harder I push it, the better the bike gets! The bike is just so balanced. Pivots will now be added to my stable...very impressed.

Would it be possible to set up a Rohloff Speedhub on this frame? If so, would I be able to use a carbon belt rather than a chain?

Responded on


That could be a great setup, but the rear triangle needs a split for installing a belt, and the Rohloff Speedhub needs a quick release frame, not a thru axle model.

Awesome Service

  • Familiarity: I've used it several times

This is the second bike i've gotten from CC and their service has been great both times. The Pivot LES 29 is a sweet bike and they did a nice job on the build.

Thanks for sharing and great bike!

Is there routing for a dropper post on...

Is there routing for a dropper post on this frame? Can you plug in a Reverb?

Responded on

There is no specific routing for a dropper post on this frame. Not too many people install droppers on hardtail frames but it can be done by trying to zip-tie the cable housing under the top tube where the brake line runs (not recommended though).
