LES is more.

As common as plaid, button-up shirts on 30 somethings, it's getting harder and harder for a new 29er to standout — especially with an ambitious and fresh 27.5-inch face stealing the limelight. Thankfully, Pivot is preventing 29er's midlife from the ubiquitous office job and a social life of mediocrity with its hardtail, LES 29 Carbon Mountain Bike Frame.

Aside from the flight-ready, jump-specific Point, the LES represents Pivot's first venture onto hardtail mountain bike territory. But, this is far from Pivot's first hula with big hoops and the almighty black fiber. Five years ago, the Mach 429 shook up squishies by mating 29er wheels with DW-Link suspension, and the Mach 5.7 has recently set a new benchmark for what is possible with carbon fiber.

What separates the 5.7 from the carbon masses is Pivot's exclusive hollow-box, high-compression internal molding technology — the same process used to create the LES' signature shapes. And those tasteful curves aren't like the false advertising of a corset. They're the result of extensive frame tuning in order to provide a sub 2.5lb chassis that accelerates with enthusiasm, yet filters body-fatiguing chatter.

Pivot's internal mold technology allows for greater compaction and smoother internal walls to produce a lighter, stronger, and highly optimized frame. The top tube and seatstays are flattened compared to the large down tube. This allows a leaf-spring-like-motion to dampen the LES' ride. This shape, however, is wider along the z-axis, so it won’t flex side to side while sprinting.

Adding color to the ride-quality picture are stout chainstays that have been mated to a 92mm PressFit bottom bracket. This provides excellent response on a geared bike, but better yet, the increased strength also welcomes the demands of single speed riding. And yes, the LES can strip the shinny bits in favor of simplicity with the separately available, Swinger drops.

Making a single speed frame is fairly straight forward, however, there are some ugly gremlins that still torment designers and riders, and they can be compounded on convertible frames like the LES. Luckily, Pivot invested ample research and design in this department. Pivot's Swinger adjustable dropout system is a dutiful approach to the issue of brake interference and chain tension. The design swings around a pivot that's located in front of the upper post mount of the brake -- it's virtual on the non-disc side. The resulting slight arc allows tensioning of the chain with a negligible affect to the LES' geometry.

The system is indexed for simple setup, and it allows vertical-drop ease-of-use when it's time to swap wheels or change a flat. At its minimum setting, the Swinger tension system gives the LES 17.1-inch chainstays. Many manufacturers claim to be packing stubbies outback, but this is one of the shortest lengths that we've come across. That translates into a bike that's eager to pull up over obstacles, bunny hop, and swing around tight switchbacks. At the other end of the geometry playing field is a 69.5-degree head tube that breaks from the traditional steeper angles of twitchy-descending race bikes. Instead, the head tube is tapered for modern 29er suspension, and Pivot recommends a 100 to 120mm fork.

The Pivot LES 29 Carbon Mountain Bike Frame is available in four sizes from Small to X-Large and in the colors Matte Carbon/red, Matte Carbon/blue, and Solar Orange. It uses a 30.9mm seatpost, a direct-mount front derailleur, and a 12x142mm rear axle (included).

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 down....best 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

Andrew,

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. If you want to chat more and try to figure out some options, please give me a shout directly.

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.

Awesome Service

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).
