THE NEW STANDARD IN HARDTAIL PERFORMANCE

The lightweight LES 27.5 sets a new standard for stiffness and power transfer. Marshalling our proprietary hollow core, internal–mandrel process, and a custom layup incorporating new, high-modulus carbon fibers, we’ve created a ride-tuned hardtail that transfers your every watt into pure speed. The LES 27.5 features an oversized, box-section downtube and bottom bracket area, stiffness enhancing Boost 110 and 148 front and rear spacing, as well as meticulously engineered seat and chainstays. Out on the course, those features add up to amazing power transfer, razor-sharp handling and a surprisingly forgiving ride quality that staves off fatigue and saves you energy on even the longest courses.

OUTSTANDING FIT AND FEEL

Our rider size-specific geometry creates a balanced fit and adjusted geometry that gives you the best possible wheelbase length and handling. Our smaller sizes are built with shorter head tubes to create more stand-over height. This enables you to ride in a centered, athletic position with tons of clearance over the top tube – precisely what you need to descend and corner with confidence and speed.

WORLD CUP PERFORMANCE FOR EVERY SIZE OF RIDER

The LES 27.5 brings uncompromising performance to riders from 4’10” to 6’1”. The LES 27.5 is a revelation of optimized geometry, stand-over clearance, weight, and ride tuning. By including sizes Small and Extra-Small in the range, we’ve got a LES model to properly fit every size rider who seeks bigger wheel performance. Size-specific carbon molds enable us to use smaller diameters and unique carbon layups to build lighter frames that maintain the same high strength in a more compact frame design. The more compact frame design of the LES 27.5 also makes it possible to build a sub-19.4lb (8.79kg) race bike – an advantage for everyone, but even more so for small riders seeking the best power to weight ratio.

FAQ

Which size bike should I purchase?

To ensure the best sizing, we recommend that you visit your local Pivot dealer to get a professional fit and refer to our geometry chart to check your measurements. However, we can provide a rough guideline: 

X-Small: 4’10” – 5’5”

Small: 5’4” – 5’9”

Medium: 5’8” – 5’11”

Large: 5’10” – 6’1”

How many water bottles fit on the LES 27.5?

The LES 27.5 in size XS has a mount for one cage and fits a large waterbottle inside the front triangle. Sizes S-L have mounts for two cages and fit two large waterbottles in the front triangle. For ease of use, we recommend side pull cages on sizes small and XS.

How much does it weigh?

Variables in frame size, discrepancies in scale calibrations, and method of weighing (with or without pedals and such) all lead to inaccurate comparisons, so we choose not to publish our bike weights. Pivot bicycles are among the lightest available, but the weight is only one of many factors that make a great bicycle. Other aspects such as frame stiffness, strength, durability, and ride quality are just as important as weight to our engineers when designing our Hollow Core Carbon and aluminum frames. Instead of comparing grams online, we suggest you visit your local Pivot dealer and see our attention to detail, smart, high value spec, and class leading features. Bring a scale if you’d like, but take just one demo ride and you’ll feel why Pivot Cycles are the most well-rounded, highest performing bicycles on the market and in many cases, yes, it’s the lightest as well.

What hub/wheel spacing does the LES 27.5 use?

The LES uses the Boost 148mm X 12mm hub/wheel spacing. This is a new hub design with wider flanges so you cannot take a current 135mm, 142mm, 150mm, or 157mm hub and change end caps to convert an existing hub.

What is the thread pitch on the rear axle?

Pivot uses a 1.5 thread pitch on the rear thru axle.

What size seatpost does the LES 27.5 use?

30.9mm

Can I use a dropper post with this frame?

Yes, the Pivot Cable Port System makes this frame internal dropper compatible.

What size seat clamp does the LES 27.5 use?

34.9mm or 35mm (as some manufacturers call it)

What front derailleur does the LES use?

The LES 27.5 uses an e-type Shimano side-swing style front derailleur only. Shimano produces the new e-type side-swing front derailleur in Deore and SLX for 10 speed drivetrains and SLX, XT and XTR for 11 speed drivetrains.

What travel fork can I use on my LES 27.5?

The LES was designed for 100mm to 130mm fork travel. 130mm is the maximum travel length to be used on the LES. We use the new FOX 32 Step Cast 100mm fork in all our complete bike builds. 

What is the fork offset on the LES 27.5?

The offset on the Fox Stepcast 32 100mm fork is 44mm.

What cranks will the LES accept?

The LES 27.5 will accept all cranks designed for the BOOST system and compatible with a Press Fit 92mm bottom bracket. BOOST system means that the rear hub spacing is 148mm and the chain-rings have been shifted out approximately 3mm from where a tradition crank designed for a 142mm rear hub would be so that the chainrings will line up properly with the new position of the cassette on the 148mm rear hub.

Can I run non-Boost™ cranks on my LES 27.5?

In some cases you can run a conventional non-BOOST 1X or 2X crank. The Race Face NEXT 1X and other Cinch system 1X cranks are dual compatible between standard 142mm and 148mm Boost rear ends. Some smaller chainring combination 1X (30 and 32T) Shimano XT and XTR 11 will also work. In some cases 2X standard cranks may also work with 24/34, 26/36 and 22/36 combinations. Shimano’s new 11 Speed XTR and XT standard cranks feature both 24/34 and 26/36 chainring options which work perfectly with the LES frame as Shimano’s chainline dimensions already tend to run wider than others in the market. There may be other 2X non- boost cranks available that will work although it is dependent on specific chainline and chainring size. If the chainline is not out far enough, the front derailleur clearance may be tight when shifting into the small ring as the front derailleur mount on the LES is also shifted outwards to accommodate the BOOST design. Additionally, you cannot run cranks designed specifically with a narrower Q Factor such as XTR Race 158mm Q factor crank and the SRAM XX1 156Q crank (In fact, for any SRAM 1X cranks, you need to run their specific BOOST version of the crank).

What is the narrowest Q factor crank that the LES 27.5 will accept?

The LES 27.5 will accept cranks with a standard Q factor measurement as low as 163mm. You cannot run cranks designed specifically with a narrower Q Factor such as XTR Race 158mm Q factor crank and the SRAM XX1 156Q crank.

Can the LES 27.5 be used as a singlespeed?

The LES 27.5 is designed as a geared bike, and is compatible with both 1x and 2x systems. For riders wanting to a singlespeed, we recommend the LES 29, which comes ready for singlespeed use with a custom dropout system designed specifically for singlespeed applications. That said, there are single speed conversion systems in the market that could allow you to run your LES 27.5 as a single speed if you wish.

What bottom bracket is used on the LES 27.5?

The LES 27.5 uses a Press Fit 92mm BB. Some bottom bracket manufacturers may refer to it as BB92 of PF92 as well. Every crank manufacture offers Press Fit 92mm BB options. 

What headset do I need for the LES 27.5?

Zzero stack (ZS) 44mm top and ZS 56mm bottom, or a Chris King Inset 2

How large of a rotor will fit on the LES 27.5?

180mm

What type of rear brake adapter do I need?

No brake adapter is needed for a 160mm rotor. However, if you want to run a 180mm you would need a 180mm direct mount/post-to-post adapter.
