Most of what we’ve seen up close of Polygon has been their gravity focused Collosus bikes, be it in its World Cup DH version or their newer N-series enduro bikes. But at the same time, Polygon has a pretty full catalog and has just introduced three new aluminum mountain bikes for three different types of riders. The Siskiu D bikes are pretty straight forward mountain bikes – 120mm of simple 27.5″ full suspension to get out and enjoy the trails in your backyard. The Entiat TR is a bit different, going the path of the 27.5+ hardtail to get your squish, and then there is the 100mm travel Trid ZZ when you really need to hit those huge dirt gaps with a solid no-hander backflip…
The Siskiu D is full-suspension mountain biking at its basics. Build an aluminum faux-bar single pivot bike with 120mm of travel and set it loose on your local trails. Just enough suspension to take it off some drops and through the rough sections of trail, but not so much that you feel like you are slogging up the climbs at the end of a long day.
With 27.5″ wheels, 438mm chainstays, and a long toptube, the Siskiu is ready to hit the trail. The bike uses a gently shaped, stiff triple-butted 6061 aluminum frame, a one piece forged alloy linkage, and a tried and true suspension platform. It also gets Polygon’s 2HRU dropouts which means it will work with either 12mm thru-axles or QR wheels is you still have a bunch of them that you like. The bike is designed to run a sideswing front derailleur and gets internal shift routing.
The Siskiu is available on its own as a frameset, or in one of three complete builds. The base model D5 gets the same frame but with a entry-level Alivio 3×9 spec. And they go up to this top-level D8 with an XT/SLX double.
The new Entiat TR gets a lot of the same frame tech – triple-butted 6061, modern trail geometry, tapered headtube, etc. – but targeting a different type of rider. With the explosion of 27.5+ wheels and tires, a lot of riders are looking back to the simplicity of alloy hardtails that are now more capable trail machines than ever.
Polygon puts the Entiat TR in the same family as its 140mm travel Collosus T trail bike. With a matching long toptube and short stem and 120mm forks, the Entiat TR throws in a dropper post and that fat rubber to eat up all the bumps and drops on the trail. Where riders used to look to hardtails for pure XC riding, now it makes sense to huck one off of something stupid again.
The Entiat gets internal shift routing as well, plus stealth dropper routing. It is built to be 1x specific, so it picks a Boost 148 rear end and bigger 3″ tire clearance over the possibility to run a front derailleur. It is available just as the TR8 spec with a mostly XT single ring build.
You know it can’t be a huge market, but Polygon has some strong roots in gravity and definitely in slope style competition with a strong presence on the FMB World tour. So they’ve built the Trid ZZ, what they are calling the best slope style dirt jumper on the market.
With 100mm of solid faux-bar suspension, the Trid ZZ is designed to take up the slack and save your butt when you are about to case a hard landing when you’ve over rotated or slightly overshot your landing. It gets a 6061 alloy frame built tougher than just about anything else Polygon has to offer. Pairing the Monarch R shock with a 100mm Pike DJ , those who are looking for this bike know who they are.
The Trid ZZ comes in one size and one complete build only with a GX DH 7-speed and 160mm DB5 brakes. It gets a nice little trick mount (no, those aren’t water bottle bosses) inside of the main triangle to place the shifter and route it internally, so it doesn’t have to get detangled after all those bar spins. Leave that to the extra long rear brake line. (although we’re not sure why the front brake doesn’t get routed through the steerer tube?) Don’t worry, the 26″ wheeled Trid ZZ can probably take a much harder landing than you can.
In addition to new bikes, Polygon has also expanded its Color It Your Way semi-custom color program. Now their top Collosus DH9 downhill bike, the Collosus N9 enduro bike, and Helios LT get more frame color options with the stock builds. It adds $100 to the stock builds on these top bikes, but you get to add a bit of personalization.
