Our Lightest Full-Suspension Frame Ever

With a massive 14.3% weight reduction, Signal Peak 3.0 lets you float up climbs and tackle every challenge with ease. In its lightest configuration, a size large Signal Peak frame tips the scales at 1732 grams. Our refined tube shaping enhances both strength and efficiency, making every ride feel effortless while keeping things simple—no proprietary parts, no unnecessary complexity, just a bike that works as hard as you do.

Evolved Geometry

Powerful Climbs, Unrestrained Descents. A more aggressive 76 degree seat tube angle places you in the optimal pedaling position, while a slacker 66.5 degree head tube angle keeps you composed and confident on descents. With room for longer dropper posts, you can unlock your full potential—climbing with power, descending without restraint.

Awesome MTB

Best Value XC Bike

The Ari Signal Peak won the award for best value XC bike of 2026 but do not let that award fool you. This is not just another XC bike at an awesome price point, but rather this is one of the most confident inspiring XC bikes that has taken me through 167 miles of XC racing at 24 Hours in the Old Pueblo and 7 days of brutal XC racing at the BC Bike Race.

TetraLink Race Lite Suspension

We’ve crafted a bike that maximizes power transfer, responsiveness, and efficiency. For those seeking a podium finish, this suspension platform gives you the stability and speed to ride with confidence.

Signal Peak's 110/120mm suspension doesn't shy away from the most brutal climbs and rowdy descents.

Travel 0 mm

Leverage ratio 2.52

At full extension, energy stored in the rear triangle helps actuate the shock leading to a buttery smooth sensation off the top.
Tuned flex in the seat stay locates the zero-energy position at sag allowing the seat stay to act as a leaf spring helping keep the bike at sag when pedaling and preventing pedal bob.
Progressive ramp-up in the carbon seat stays provides a controlled end stroke so you can charge on the descents.

01 Unbox and check contents

Remove packaging foam and zip-ties. Confirm the small-parts box has pedals, thru-axle and multitool.
02 Install the handlebar

Center the bar, set roll, and tighten faceplate bolts evenly in a cross pattern.
03 Fit the front wheel

Seat the rotor between the pads, insert the thru-axle from the non-drive side and close to spec.
04 Set saddle height

With the dropper fully extended, set height so your knee is slightly bent at the bottom of the stroke.
05 Install pedals

Grease threads. The left pedal is reverse-threaded.
06 Set suspension and tires
Set sag for your weight using your fork and shock manuals, then check tire pressure against the sidewall range.

General Technical Support

What is the Signal Peak 3.0 designed for?

The Signal Peak 3.0 is a lightweight, high-performance cross-country (XC) bike built for both competitive racing and aggressive trail riding. It offers the perfect balance of efficiency and control for riders who love fast climbs, technical descents, and long days in the saddle.

Who is this bike for?

The Signal Peak 3.0 is ideal for two types of riders: XC Race Ready: Those looking for the fastest XC bike with maximum power transfer and lightweight performance. XC Trail Ready: Riders who enjoy technical trails and want a bike that climbs efficiently and is fast and fun up and down the mountain.

Where does the Signal Peak fit in the Ari mountain bike lineup?

The Signal Peak is a cross-country XC bike. In simple terms, it is built for those who generally prioritize ⅔ climbing and ⅓ descending. In comparison, the Delano Peak is designed for riders who generally seek 50/50 climbing to descending balance, while the La Sal Peak is generally for riders prioritizing ⅔ descending and ⅓ climbing on the other end of the spectrum.

Are financing options available?

Yes, we offer convenient financing options, making it easier to get your dream bike without paying all at once. Click here for more details.

How does the Ari Custom Setup work?

Every Ari bike is custom set up for the rider using the Ari Custom Setup, ensuring that your bike arrives dialed in for optimal performance and comfort.

What is included in the Signal Peak 3.0’s complete builds?

Each build comes with a carefully selected mix of high-end components to maximize speed, durability, and ride quality. Build levels vary, offering options for racers and trail riders alike.

What is the weight of the Signal Peak 3.0?

The Signal Peak 3.0 features Ari’s lightest full-suspension frame ever, weighing just 1,732 grams for a size large. Complete builds can be as light as 24 lbs in stock configurations including a dropper post, 4-piston brakes, and tires that will last - you want light, but you also want lasting performance. Signal Peak gives you that.

What makes the Signal Peak 3.0’s suspension design the best for XC?

The TetraLink Race Lite Suspension Platform eliminates a pivot, creating a unified rear triangle for increased lateral stiffness, reduced weight, and improved power transfer. This results in exceptional suspension efficiency for both racing and trail riding.

What is the tire clearance?

Rear tire: 29 x 2.4 inches. Front tire: suspension manufacturer dependent (typically 29 x 2.4-2.6 in).

What is the Zero-Energy Flex State at Sag?

Specific, tuned flex in the seat stay locates the zero-energy position at sag. This allows the seat stays to act as a leaf spring, ensuring that the bike stays in an optimal pedaling position while preventing energy loss from pedal bob. This enhances both pedaling efficiency and suspension responsiveness.

What are the key geometry changes in the Signal Peak 3.0?

The Signal Peak geometry is all-new on this latest generation. Some notable highlights are: 66.5° head tube angle (0.5° slacker than previous gen) for confident descending. 76° seat tube angle (1° steeper than previous gen) for a powerful pedaling position. Straight, uninterrupted seat tube for compatibility with longer dropper posts.

How is the ride quality improved?

Silent Ride Experience: Tube-in-tube cable routing eliminates rattles, and custom-molded protectors keep the drivetrain whisper-quiet. Mounts for 3 water bottles to support long rides without compromise.

What is Full Mount UDH compatibility?

The Full Mount UDH system allows for easy drivetrain maintenance and ensures compatibility with the latest (wired or wireless) drivetrain technologies, keeping your bike future-proof.

What type of bottom bracket does the Signal Peak 3.0 use?

The bike features a threaded bottom bracket, ensuring durability, reliability, and easy maintenance.

How will it arrive?

All Ari bikes go through our Custom Setup process, making sure the bike is fit and tuned specifically to you. They are test-ridden before delivery. If your bike is shipped to you, it’s still tuned and ready to ride and requires just a few minutes of assembly.

What about service?

You can work directly with us, one of our recommended shops, or work through your local shop.

What is the warranty?

Every Ari frame has a Lifetime Warranty against defects in materials or workmanship for the original owner. Paint, original components, bearings, bushings and frame hardware are covered for one year. If you sell the bike, the second owner gets a one-year frame warranty (one transfer, registered with Ari). Framesets bought on their own are covered only when Ari assembles them with components from an approved stock build. Crash damage isn't covered, but Ari may offer discounted crash replacement parts. Read the full warranty.

What is the guarantee?

Every new Ari bike comes with the 30-Day Love It or Return It Guarantee. Ride it on your own roads and trails for 30 days from the day it arrives, and if it isn't the right bike, you can return it. Contact the Ari team for a Return Authorization (RA) number before shipping it back. Damaged bikes, electronics and pedals are excluded, Ari Outlet bikes are final sale, and you pay the original and return shipping. Read the guarantee terms.

How does transferable warranty on Ari bikes work?

Ari-branded frames come with a transferable frame warranty available to the second owner. The second owner can receive a one-year frame warranty from the date they purchase the bike from the original owner. Warranty only transfers once. All Ari bikes must have the transfer documented from the original owner to the new owner here in order to qualify for a transferable warranty.
