Cross-country bikes are stretching out towards more travel as carbon frames get lighter, race tracks get more technical, and modern trail capable geometry gets dialed. Fezzari’s new 120mm carbon Signal Peak is a perfect example, ready to fly fast up long, steep climbs and then hammer through rock gardens and down technical descents. While we might say it makes for an all-around mountain bike, Fezzari calls it an XC Weapon.

Fezzari Signal Peak trail-ready 120mm carbon XC bike

Technical XC race courses have evolved back closer to the everyday trail riding most of us actually ride. And that has meant that race-ready frame and component designs have for the most part left fragile designs behind and yielded light, capable mountain bikes that are just fun to ride. The Signal Peak was designed with the all-around racer or recreational rider in mind.

A light, efficient pedaling carbon frame with a prominent pedaling platform will get you up the climbs quickly. And that same oversized frame shaping, progressive suspension design, and slack geometry make it handle confidently when trails get rough and technical.

Starting from a sketch to improve their new XC bike, Fezzari build alloy prototypes to refine the bike before settling in on the final geometry.

Tech details

The new bike shares a similar four-bar Horst link suspension layout to Fezzari’s alloy 130mm trail bikes and their current carbon XC bike – the Hidden Peak. But a slacker 68° head angle, a steeper 75° seat tube, and much shorter 430mm chainstays yield a bike ready to go faster both up and down hills.

The new 1x-specific carbon frame claims a weight of just 2000g (medium), and incorporates high anti-squat in its suspension design to make for a solid pedaling platform with minimal pedal-bob. Opposite the designed in pedal platform, Fezzari claims small bump performance but a progressive movement through the travel for an endless feel to the 120mm of travel.

And to make it work with a mix of riding styles and terrain, you can pick whether you want to ride 29″ wheels with up to 2.6″ tires, or go 27.5+ up to 2.8″ tires. A two-position flip chip at the rear shock mount lets you preserve geometry while easily swapping wheel sizes.

The little details

In the little details, Fezzari give the new Signal Peak a modular internal routing setup that is designed to be rattle free, clamping onto the cables. It also finally moves to internal routing for the stealth dropper seatpost.

The Boost spaced frame features custom molded downtube & chainstay protectors, plus a metal plate to protect the frame against chain suck. The frame features two sets of water bottle bosses inside the front triangle on all sizes (two position on larger frames), and sticks with a traditional threaded bottom bracket to keep things simple.

Complete builds, pricing & availability

The Signal Peak is available in three complete builds, and four sizes (S-XL). The top-level Signal Peak Pro sells for $6200 and gets a premium build with a new 120mm Fox 34 Step-Cast fork and Float DPS shock both with Factory level Kashima coatings and a matching Transfer dropper. Drivetrain is handled by a full SRAM XX1 group, Level Ultimate brakes and Reynolds TR 249 S wheels.

The $4000 Signal Peak Elite gets Performance-level Fox suspension, SRAM GX Eagle, Level TL brakes, and Xfusion Manic dropper, and Stans Arch Mk3 wheels. The most affordable Signal Peak Comp at $3000 has a RockShox Reba RL fork & Monarch RT3 shock, an undefined NEW SRAM Eagle drivetrain, Level T brakes, no dropper, and WTB I25. The Pro & Elite will be available from May 1st. The Comp will have to wait until June 11, presumably when that new SRAM drivetrain will be ready. As with all other Fezzari bikes, the Signal Peak is backed by Fezzari’s No Risk, Just Ride Guarantee that includes both a 30-day no-risk ride or return policy and a full lifetime frame warranty.


  1. I like the dark blue color. These photos appear to have been taken at Lambert Park in Alpine Utah. Except the yellow one, which looks like it was taken at the company parking lot

    • Stan’s Crest CB7 carbon are available as well. The bikes are custom built so you can pick your spec if you’d like.

  2. I’d be curious to know the weight of the Signal Peak Pro. Overall, this looks like a well thought out bike with my only beef being with the rims. Ideally I would pick up the Signal Peak Pro for $5,000 but sans wheels.

    • The Signal Peak Pro in the photo and that is being shown at Sea Otter is a size large. The full bike with Fox 34 Step Cast 120mm travel, 125mm dropper post, and 780mm bars came in at 24.5 pounds. If you prefer a different wheel setup, Fezzari can do that too.

    • But but but, its better cause everyone is doing it just like pressfit bottom brackets (ignore that creaking you THINK you just heard, it never happened)…..

  3. So I bought the bullet and ordered one of these. First off, the Fezzari 19-point custom fit process is a complete joke. I got a call from Fezzari saying, based on your measurements you are a large. No kidding! It’s just like with any other mass market bike, there’s no customization of handlebar width, crank arm length. I also think it’s criminal that it’s spec’ed with 29×2.2 small block tires. I know it’s so they can list a lower weight, but in this day and age, way too narrow. How does it climb? Well, I had worse times on all my favorite climbs than on my 6-year old 150mm travel 26 inch wheeled mountain bike. Did I mention that it descends worse than my old school Scalpel with 100mm travel and much steeper angles? I found nothing redeemable about the bike, especially for the build that I bought at 5K. Luckily Fezzari honored their money back guarantee. On paper the bike looked great, but in reality it didn’t work for me at all.
