2021 Cannondale Trail 8 Review

The new 2021 Cannondale Trail 8 is the cheapest mountain bike by Cannondale.

It features all the modern features to get the beginner cyclist on two wheels and out on the trails. Sure, $600 for a mountain bike is pretty much the lowest you can go and still expect a solid ride out of it, but the Trail 8 is definitely here to show that it is worth every dollar of it!

2021 Cannondale Trail 8 – Full Review

Cannondale Trail 8 is a phenomenal mountain bike that doubles as an everyday commuter. It has everything a beginner rider would be looking for — low price, dependable components, durable build, and good looks! Even though Trail 8 has wide tires that make it suitable for off-road riding, it is not intended for extreme trail rides and abuse. Its entry-level components wouldn’t be able to take it for very long.

One of the things that owners of Cannondale Trail 8 praise the most is handling. This is neither a light nor a small bike, but its geometry makes it swift and efficient both on and off trails. The variable wheel size (27.5″ or 29″) ensures the best possible fit. Short people find it easier to control smaller and lighter 27.5″ wheels, whereas taller riders will get to enjoy the more functional benefits of the huge, 29-inch trailblazers.

Trail 8 is a bike made for casual riders who wish to have some fun on dirt roads, explore unpaved routes, and take short commutes in the city.

Aluminum Frame & Fork

  • Aluminum frame that Cannondale uses on many of its bikes. The SmartForm C3 alloy, as the material is called, is light and feels nimble on trail rides.
  • Semi internal derailleur cable routing, rear rack, and fender mounts, and two water bottle mounts. The geometry is comfortable and upright and the design is sleek and simple.
  • The SR Suntour fork with 75 mm of travel, which is enough to eliminate vibrations, help you jump curbs, and conquer potholes.

Entry-Level Components

The reason why Trail 8 costs just $575 is due to entry-level components, but that does not necessarily mean they’re bad. Those level of components is intended for beginners cyclists or intermediate commuters who go easy on the bike. Shimano Altus derailleur on the front and Shimano Tourney on the rear make up 14-speeds. They’re excellent for weekend adventures, casual commutes, and easy-going workouts. If you plan to use them for a lot more than that, you’ll find them lacking in precision and durability.

Disc Brakes

The Cannondale Trail 8 is equipped with mechanical disc brakes which are not fancy by any means, but the performance and stopping power they offer is much better compared to V-brakes. Disc brakes ensure excellent braking in all conditions, which is especially important if you plan to ride in wet weather, snow, and mud.

Wheels and Tires

The burly wheels and knobby tires are the most important parts of the Trail 8 bike. They give it versatility and make it suitable for off-road riding and ready to tackle some serious terrain.  The smallest frames (XS, S) come with 27.5″ wheels, whereas larger frames are built on 29″, 32-hole rims. The tires on all wheels are WTB Ranger Comp, 2.25″ wide. These wheels are a bit heavy, but they are durable and roll well over obstacles. The tires are quite knobby, so you should expect plenty of grip.

Cannondale Trail 8 Frame Size Recommendation

Cannondale Trail 8 is available in five distinct frame sizes, which is enough to find the right fit no matter your height.

XS: 4’6″ – 5’2″
Small:
5’1″ – 5’4″
Medium: 5’4″ – 5′ 8″
Large: 5’7” – 6’0″
X-Large: 6’0″ – 6’3″

Note! Cannondale bikes are well-known for their long top tube, so whenever you fall in-between two sizes – it is recommended to go for the smaller than you’d get with any other bike. Larger bikes are better for long-distances riding, while smaller mountain bikes have better handling on off-road trails.


 

Should You Buy the Cannondale Trail 8?

Trail 8 is a safe buy for beginners, casual riders, and first-timers on the trails. If you recognize yourself in any of these three categories, we believe this bike would be a good fit for you.

Cannondale Trail 8 is a versatile two-wheeler that can complete different types of tasks and handle a variety of terrain. Plus, it costs less than $500, which is a big plus.

Its entry-level components are more than good enough for average cyclists who are just looking for a way to get from point A to point B or spend more time outside!

Cannondale Trail 8 ‘2021 Cons

Although this is a hell of a bike for this amount of money, let’s not forget that it is the cheapest mountain bike by Cannondale

The Trail 8 best suited for those who tackle light trails or simply need a bicycle for urban commuting. Don’t get me wrong, this bike is very capable of cross-country/marathon type riding.

  • Rear Derailleur – Needs adjustments every now and then, not the smoothest nor the most durable of the bunch.
  • Grips – Cheapest, might not be the most comfortable for long-distance riding.
  • Saddle – You kind of get to feel the steel rails after 30mins of riding.
  • Fork adjustments – Unclear how to adjust the forks by the dials.
  • Weight – Even though the bike is on an alloy frame, it is quite heavy.
  • Chain slap – You might want to get a neoprene cover to protect the paint and stop the chain-slap noise.
  • Low bottom bracket – Look out for pedal strikes when cornering.

The 2020 model

After all – this is a personal opinion from an experienced mountain biker. It costs about $100 to get rid of those downsides to enjoy the bike where it is best suited for! For recreational mountain bikers, there’s a lot of bike for the money!

    If you were to upgrade any of the part on the Trail 8 what would they be? Im just getting into mtn biking and I want a reliable machine on the trail. Please describe the part you would replace with so I can make a list and start buy those piece. Tnx for any help with this matter.

    1. Sam Millers says:

      It depends how often are you going to use the bike and how heavy are you. The weakest part about used to be the Shimano Tourney derailleur which they have fortunately updated to microSHIFT. Front suspension plays a huge role too, and currently there’s a heavy coil shock which might not be the smoothest, but does its job at its price range. Other than that, I didn’t have major setbacks.

      It is best for recreational commuting on mixed terrain and definitely worth its price. If you are planning on updating the parts, take a look at best under $1,000 MTB’s, there’s quite a noticeable gap there.

    Hi, do you have cannondale trail 8 or any number?

    1. Sam Millers says:

      Hi Romero

      Cannondale Trail 8 has been among the most popular bikes for a long time, hence the reason their bikes are often sold out quickly.

      We’ll e-mail you once their bikes come up for sale again!

    I recently bought and subsequently returned a Trail 8 ‘2021. Great looking bike, but despite 3 repair attempts (in 2-weeks) at the shop, they could never get it right. BTW, the shop (Sun & Ski) was great and I will be a customer moving forward.

    I brought in the bike after having it for a couple of days because the chain was literally falling off and because, when the chain stayed on, it felt like it was slipping when going uphill or while standing to peddle (particularly while in the 7th gear). The shop fixed the chain falling off issue, but the chain slipping persisted. The second time I brought it in, the shop told me that Cannondale knows of this issue with the Trail 7 and 8 for L and XL bikes (possibly bigger guys) and advised to replace the cassette. While my bike was only a M and I’m only 140 lbs, the shop replaced the cassette, but that didn’t fix the problem either. This led to my third attempt to get it fixed, but after leaving it for several days, they couldn’t fix the problem, so I returned it.

    In the meanwhile, I contacted Cannondale customer service and they were absolutely not helpful at all. They didn’t offer any solutions, but wanted to know if the shop was able to fix it or if they refunded my money. When I told Cannondale that I returned the bike and that I was very disappointed with my first experience with their brand, they responded: “Thanks for the update Joe, We are very sorry to hear the bike did not work out. All the best, Jeffrey”. Wow!

    1. Sam Millers says:

      Hi Joe

      Thank you for your honest reply. Matter of fact, I had excactly the same issue on the frame size L which turned out to be a bent rear derailleur. Make sure to get the bike assembled correctly, and don’t forget to re-tune the bike after 10-20 miles of easy riding. I upgraded the bent Tourney rear derailleur on my 2020 Trail 8 and it fixed the problem.

      Regards,
      Sam
