Mountain Bikes


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. Mountain bikes whilst designed for off road riding can also be versatile enough to be used on road. Mountain bikes 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 mountain bikes typically run 100mm to 120mm of travel, Trail and Enduro mountain 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. 

Mountain bikes 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.

2016 Polygon Siskiu D7.0 Dual Suspension Mountain Bike - Large 19.5 inch

Had the Siskiu D7 for about a month now, Very happy with this bike. Really well kitted out for the price. Initially I had too much air in the fork as i looked at the 80mm travel chart not the 120mm, after correcting this the fork was really compliant over small bumps and tree roots. Both the fork and shock rebound adjusters are effective with noticeable changes in compliance and handling. Lockout is very effective on both fork and shock if commuting is also on the agenda. Competed in a 12hr and a 4hr race on it plus numerous other rides with no problems at all so far. I did sack the original tyres and went tubeless as the original tyres were quite puncture prone and lacked a bit of grip in the dirt, no more punctures since. This really makes you wonder why you would spend multi thousands of dollars on a bike when this one does everything so well.

2016 Polygon Collosus T6 - Trail Bike

2016 Polygon Collosus T6 - Trail Bike

By: on 20 April 2016
For the group set you can't go past the price of this bike!!! Took this bike to Pemberton and it worked flawlessly, did a lot of checking of bikes (different brands) and the gear and price point of this bike makes it hard to go past. My previous bike bounced a lot when peddling, the technology in this bike eliminated that. Only fault (although not sure it's a fault) is the paint seems to scuff easily. Customer service - over the internet you are always cautious, but their C/S is excellent and fast, their was a problem (minor) that happened during transport, problem was rectified quickly more than I expected.
