Yeti Cycles brings something different to the 650B market with its long-travel SB140 trail bike. Find out the performance specs of this trail masher in this Yeti Cycles SB140 Review.

The Yeti SB140 C1 bike is an excellent choice for the versatile trail rider looking to experience exceptional fun on the trail. Engineered around the brand’s C/Series carbon build, stocky tires, and Switch Infinity technology, this trail bike is remarkably responsive and nimble.

The C1 C/Series is one of the five complete builds of the SB140 model, and it is the least expensive build kit.

If high-speed trannies plus zipping, twisting, and dodging obstacles on the trail top the list of experiences you want while mountain biking, you may as well consider Yeti’s most playful but capable trail ripper yet – the SB140.

Yeti SB140 C1 Overview

Yeti SB140 C1 Overview

Yeti’s mountain bike lineup features awesome bikes, and the SB140 is not an exception. Yeti did not design the SB140 model to be a race bike or something you ride on straight roads, at least not if you want to have fun with it. Instead, this bike makes your everyday trail a blast as it corners extremely well at high speeds on trails!

The SB140 C1 features a carbon fiber frame and 27.5-inch wheels. It has 140 mm of rear travel paired with a 160 mm fork that works seamlessly with the brand’s patented Switch Infinity suspension system.

If you’re familiar with Yeti Cycles, you’ll know these are just a few out of the long list of first-rate and inventive features of the bike. But before we properly dive into the Yeti Cycles SB140 review to see the major performance features, here are some pros and cons of the C1 C/Series.


  • Excellent Fox factory suspension
  • Rolls quickly and climbs efficiently
  • Luxurious and supportive Switch Infinity rear and front travel
  • Available in three colors across five frame sizes
  • Hydraulic disc brake with excellent stopping power


  • Low stock handlebars
  • 27.5-inch wheels don’t feel quite like a plus category
  • Heavier than the Yeti SB5 model it replaces
  • It is quite expensive

Things to Consider Before Buying a Mountain Bike

Mountain Bike

Your budget is not the only consideration when choosing a mountain bike. Here are some other things to keep in mind when shopping for a model that will work for you:

  1. Bike Style: The first thing you want to do is figure out the kind of riding you will be doing before even browsing through the different bike models available. When it comes to mountain bikes, your choices include:
  2. Trail: Go for trail mountain bikes if you want a versatile model that can handle climbs as well as descents.
  3. All-mountain / Enduro: These types of bike styles are usually downhill oriented, so you’ll have to do more pedaling when you’re riding uphill. But they have more suspension, meaning they offer impressive stability even on gnarly trails.
  4. Cross-country: Consider a cross-country bike if you want a powerhouse bike engineered for speed and increased efficiency. This bike style typically offers less impact absorption, though.
  5. Downhill: If you plan to ride on steep terrains mostly, the hefty build of downhill mountain bikes makes them a great choice, but they are not designed to pedal uphill.
  6. Fit: The best mountain bike for you is one that fits you right. Choosing a bike with the right size and fit is not just for your comfort during rides but also for safety.

Mountain bikes come in small, medium, and large sizes. One way to find out what suits you is to measure the standover height.

Consider a bike with 2-inches or more of clearance between the top seat tube and your body when you stand over the bike with your foot flat on the ground. Another way to measure this is to check out the fit guide or size chart.

  1. Build: The frame material and suspension are two of the biggest factors that determine a bike’s build quality and price.

Carbon fiber and aluminum alloy are the commonest frame construction materials for mountain bikes. Choose a carbon fiber frame if you prefer a lightweight bike. But this is usually more expensive. Aluminum alloy frames come at lower prices and offer great durability.

When it comes to bike suspension, your choices include hardtail and full suspension. Hardtail bikes do not have a suspension at the rear, so they offer less impact absorption capabilities.

Full suspension bikes come with both front and rear shock, resulting in smoother rides with better impact absorption. However, the sophistication of manufacturing full suspension bikes makes them more expensive.

  1. Wheel Size: Mountain bikes have three wheel sizes: 26”, 27.5”, and 29” (fondly called 29er). Larger wheel sizes (29-inch) offer the advantage of easily rolling over obstacles on the trail. The downside is that they are not the easiest to handle.

Consider 27.5-inch wheels if you want to strike a balance between easy handling and tackling tougher or steep terrain.

  1. Accessories: Lastly, you should have a budget for a few useful accessories, such as a dedicated trail helmet, padded liner shorts, glasses, gloves, and more.

You may even want to change the tires, tune the gearing, or even adjust the cockpit length. All these will cost extra cash. Thankfully, they count as upgrading your bike!

Features and Benefits

While nothing beats physically take a bike for a test ride, this part of the Yeti SB140 C1 review will highlight the bike’s performance specs, so you can get an idea of what to expect if you choose to go for it.

These are the major performance features of the Yeti SB140 C1 C/Series:



The Yeti Cycles SB140 C1 bike is engineered using a C-Series carbon frame. This frame has the same strength and stiffness found in Yeti’s TURQ Series, although it is a bit heavier.

The bike has an aggressive yet playful geometry. This design gives it increased agility and gets the wheels off the ground.

With a steering angle of 65 degrees, descents are always fun and the 77-degree steep seat tube angle provides a comfortable riding position during climbs and descents.

To top it all, the internal cables routing gives the frame a neat look. Besides aesthetics, the wiring makes for easy maintenance and quiet rides.

Suspension System

Suspension System

This model boasts of the Switch Infinity Suspension – the standout feature of most Yeti bikes. The suspension system is tailor-made for extreme fun on the trail. It uses a translating pivot that switches direction during rides.

In a nutshell, the Switch Infinity Suspension reduces kickbacks and provides you with an efficient pedaling platform.

The suspension together with 140 mm of travel in the rear, an upgradable Fox Performance 36/160mm fork, and DPX2 rear shock all combine to provide you with smooth rides, every single time!

Wheel & Tires

Wheel & Tires

The SB140 rolls on 27.5” wheels that are 30 mm DT Swiss M1900 on the C/Series (and XM1700 on the TURQ Series).

The lightweight aluminum rims go well with wide 2.6” tires. Yeti uses the same tires across all SB140 build kits, with the front wheel featuring a Maxxis Minion DHF 2.6 Exo tire and Maxxis Rekon 2.6 Exo on the rear.

These tires are extremely durable and excellent for dry and hard-packed trail riding. But these might not work so well if you plan to ride in muddy and wet trails.



The bike features an efficient Shimano SLX 1X drivetrain with 12-speed transmission. This gearing and drivetrain will take you wherever you want without fail, regardless of whether it is a post-work ride or an all-day epic ride.

Shimano SLX 4 Piston brake is more than capable of providing reliable stopping power in all riding conditions for Yeti’s C1 C/Series. It can slow down when necessary so you don’t bump into trees, even when you ride at high speeds during descents.

The brakes work well with the Shimano SLX drivetrain to provide greater control and confidence on the trail.
