Which Mountain Bike should I buy?

 


Mountain bikes have a very wide range of uses, depending on the type of terrain that you are riding in. This includes Cross Country (XC), Trail, Enduro, Freeride, Downhill and Dirt Jump. Mountain bikes are the most popular type of bicycle sold in Australia and for good reason too. Whilst designed for off road riding can also be versatile enough to be used on road. They are designed with durability in mind, as they have to withstand much greater wear and tear whilst off road. 

The most common are hard tail mountain bikes, this means that they only have suspension at the front of the bike, and the rear wheel is fixed solidly to the frame.  As the trail gets rockier, however you then need dual suspension, which is suspension at the front and the back of the bike. This allows the bike to soak up the bumps and to maintain traction. The more difficult the terrain the more travel in the suspension you will need whilst descending . This allows for more variations in the trail, and bigger jumps. 

More suspension travel is not necessarily better. In fact you want as little travel as possible for your riding style. Cross country bikes typically run 100mm to 120mm of travel, Trail and Enduro bikes typically run 140mm to 160mm of travel and  Long travel bikes such as downhill and freeride normally run between 180mm and 200mm of travel. The trade off with more travel is usually the weight which makes it harder to pedal the bike up hill. 

Within all these disciplines, there are different wheel sizes, 26 inch, 27.5 inch (650b) and 29 inch (29er). The larger the wheel the easier it is to roll over obstacles, but the wheel also becomes heavier and less agile. Typically people will choose according to their height, riding style and of course – cost. 

Sizes are measured in inches, or sizes such as Small, Medium and Large. They are not as precise as road bikes, because you are often out of the saddle as you manoeuvre through corners and around obstacles so there is typically more adjustability within the size options.

Polygon Bend CT5 - Urban Sport Disc Bike [Size: XL (height: 195-205cm)]

I got this bike as a replacement for a more traditional road bike as it's a little more versatile and I really only ride for commuting. The only thing I was worried about was the SRAM shifter, as I'm used to Shimano. I needn't have worried, it took no time at all. :) All up I'm very happy with this bike, it's an outstanding commuter and very robust. The assembly was easy and I was off and riding after an hour or so. I do wish the gearing was a little higher; with 38T on the front I've never used the 42T gear on the back, I'd probably prefer 42/44 on the front, it'd give me a little more speed at the other end of the gearing. I do a 22km each way commute 3 days a week and it's held up perfectly over the last month or so. All this in spite of my size (193cm) and weight (>110kg) I'd happily recommend it to anyone.

The build quality on this bike surprised me, as i have always bought well known bike brands, Not many great value bikes like this end up on your doorstep so fast at a click of a button! The mechanic also did good job and installed a quick link! I hope polygon sticks with the subtle stealth paint jobs like this and would definitely consider in the future.

2017 Polygon Siskiu D8.0 Dual Suspension Mountain Bike

2017 Polygon Siskiu D8.0 Dual Suspension Mountain Bike

By: on 27 March 2017
This bike has been designed as a XC Trail bike with a focus on versatility and low cost. when my beloved camber comp was stolen I was discouraged at the cost of an equivalent bike to meet my requirements. I needed a bike to... Commute, dash casually around my local XC trails and compete against carbon equiped acquaintances on strava and in multiday stage races. And I wanted suspension... Multiday events on a hard tail isn't something I am into. So.. For the stated purposes above the Siskiu is ideal. Very capable on road and off. Light. Quality suspension, drive train and even the brakes. I expected the brakes to be rubbish but they are good... Great even. polygon have coupled a basic single linkage system with a quality simple rockshox offering. Air sprung, rebound adjustable suspension that is on.. Or off. No compression adjustment on the fly like RL products. My only complaint is the stupid lockout lever for the fork. It just makes the handle bars cluttered. I guess people think it's "cool" but it will break in the inevitable crash to come. The suspension linkage is simple by modern mtb terms but shock technology is now so good that I haven't noticed peddle bob or limited performance. The Siskiu out of the box is set up for XC but is easily modified for the trail end of the spectrum.. Remove the front derailer, add tubeless aggressive tyres, a dropper post and done, Trail bike. the bike also looks better than I expected, bikes online don't really sell this bike well. If you never had a suspension bike before it really is a bike to get excited about.
