Sale of the Sentry

Sentry Enduro Bike

Sentry Enduro MTB

Well if you are one of those big name brand junkies then, this is not the bike for you. You obviously have so much cash that you do not need to read about the Sale of the Sentry. I first saw this bike when I visited my local Go Outdoors. You heard it right Go Outdoors. Over the last few years Go Outdoors have aggressively attacked the premium MTB market and they have had massive success with their Bossnut Budget full suspension MTB’s.

The Bossnut came along and turned the market upside down, everyone was so surprised when it appeared under a grand and with some cracking components. The latest Bossnut is now £1100 but it is a much evolved beast. Read about it HERE.Calibre Sentry

Back to the Sentry

Again Calibre have hit the market with something that is truly a game changer. You are looking at a truly capable Enduro Bike at £2070 (WITH DISCOUNT CARD). Now some of you will stop reading because it is 2K. Other readers will now get excited as this is a very low price for a bike of this kind. We are not talking about a budget machine here. We are talking about a quality product with some brilliant components.

Here are some highlights for me.

Let’s start with the geometry of the frame. We have a head angle of 64 degrees which is lovely and slack when you are flying down those hills. This is a great benefit for an Enduro bike as it adds to the agility of the ride.

The Calibre frame is well-built and very strong and the whole bike comes in at a respectable 16.2 kg. This is not bad for a full suspension machine.


Up front with have the ultra reliable RockShox Yari with 160mm of travel and a 42mm offset. These forks are built to take a bang. The Yari will not let you down and 160mm of travel is more than enough for most riders.

Rear ShockRockShox

At the Back end we have the RockShox Deluxe R 230 x 62.5mm which is a cracking Shock. The deluxe carries a lot of travel and it is able to absorb pretty much any terrain. This if often one of the first upgrades for a bike at this price point.

BrakesCalibre Sentry

What can I Say about the choice of brake. Well I love it as I am a bigger rider and I need some serious stopping power. Calibre have gone with the SRAM Guide RE. These are 4 piston stoppers with great modulation. They will stop you very reliably. Calibre have gone for a nice big 200mm rotor at the front and a 180mm at the rear, just to give some extra stopping power.


Calibre Sentry

Calibre have gone with the celebrated and reliable SRAM NX Eagle 12 speed. They have carried on the Eagle theme through the whole drive train and gearing. Everything from the 32T front cog all the way through the chain, Cassette, Shifters and Derailleur. Those extra gears and the large rear cassette will keep you going over all terrain.

Dropper Post

The must have upgrade of the moment is the dropper post. If, you have not seen a dropper post before then you probably are not that keen on MTB. This device allows you to lower your seat out of the way while you are riding. This gives you extra stability and flexibility over the bike when on the trail by letting you move around. You can the return the seat to its original position while you are still riding. The Calibre Sentry comes with the 150mm Kore Mega Dropper post already installed. No need to rush out and get one so, you are already to roll.

These are just the highlights of the bike which I feel justify its position in the market. Here is the full spec list for you.

In Conclusion

Well in my mind this bike is a bargain. It is packed full of great kit and it is aimed to take down the market leaders. Calibre are pretty new to the Premium MTB market and I feel that these bikes are not packed full of profit. I feel these bikes are more about building reputation within the market than they are about making money. Many top end riders have hit the serious trails with these bikes and most of them have come back with some very positive views.

This bike in particular is something special to see. It is long, lean and slack. It looks great and basically it is great.

Over the next few years I can imagine the spec and prices will start to creep upwards and as they start to populate the market, they will be taken seriously by the hardcore MTB fans and riders. At the moment if you can get out of the BRAND mindset, you will bag a cracking Enduro big for 2K.
