2018 Polygon Siskiu D Frameset

$749.00


 

The Polygon Siskiu D8 received consistent, positive feedback from the industry last year. Flow Mountain Bike's review noted the D8 had "such solid performance and reliability from the components fitted to a sturdy and well-thought out frame". Mountain Bike Australia Magazine also reviewed the D8 and said the bike has "amazing spec for the dollars" which have been built around a frame that was "stiff and respectively light".

This Siskiu D8 for this year, like the D6 and D7 models that precede it, also features Polygon’s proprietary 2THRU system. This system allows the rear axle to use either a 9mm quick release skewer, as supplied, or a 12mm thru axle. This future-proofs the bike should you decide to upgrade your wheels in future.  Whichever axle you choose the design results in a much stiffer rear end with more predictable handling and better cornering. The 9mm quick release can be run with a 135mm setup using the two supplied spacers or you can run the 12mm through axle at a 142mm setup without the spacers.
