I'm just after some advice between these 2 bikes. I have no idea on which components are better on each bike, so I have no way of comparing the 2. https://www.bicyclesonline.com.au/2018- ... ntain-bike – $699 https://www.trekbikes.com/au/en_AU/bike ... Code=black – $849 (but can get for $721 with Bupa discount). The prices of them both are very similar – $22 difference. They're both close by, so can pick them up easy enough. I only do a bit of trail work, so narrowed it down to these 2 bikes in my price range, but I have no idea which is better. I do notice that the polygon is 700g lighter, but wondering if they're comparing a 27.5" medium bike to the trek 29" medium bike?? Can anyone help me decide between the 2 pls?
