As we mentioned above, it took us a little while to find a happy spot with the Siskiu’s suspension set up as the rear shock was temperamental. Once we got it dialed, the bike performed a lot better and handled big hits and small with aplomb. The Polygon Siskiu T7 certainly descends at the top of the pack. It just naturally puts the rider in a more aggressive riding position and the geometry combined with extra travel give it an advantage when things get steep and fast. It’s definitely the budget bike we’d recommend for jumpers, enduro guys and those who are looking to ride hard.
The downside to the bike’s downhill prowess is that it doesn’t climb as well as the Giant or Canyon. Granted that may not be an issue for some riders, but it’s worth noting. Our testers loved having a tire with a quality tread pattern and some grip, but those knobs slowed the bike down on flat trails and while climbing trails while the 120/130mm bikes with semi-slick tires pulled away. We found that the suspension on the Polygon Siskiu bounced a bit while on the pedals and resulted in some power loss, but it wasn’t terrible and is certainly worth the penalty if you’re a downhiller.
Normally retailing for $1,999 the Siskiu T7 is currently on sale for $1,799 and at that price it gives the Marin a real strong run for best performance for the price. The Polygon’s ExaForm 150mm dropper post worked fine during our testing and was definitely welcome on steep descents. The SRAM SX 12-speed drivetrain is certainly nice to have, but we can definitely see a difference compared to higher-end Eagle kits as the derailleur required some more fidgeting and cable tension adjustments. Ultimately though, having the range is a benefit for riders who are looking to pedal to the top of their favorite downhills.
