Tested: Polygon Siskiu N9 2019

Nov 2018

What makes this bike special? It’s not just the price, though at $3699, this one is hard to beat.

Polygon Siskiu D5 review - MBR

Aug 2018 · Alan Muldoon

Yes, the Polygon Siskiu D5 frame is top-notch but the parts spec is lacking. If it was £750 it'd be a steal but it's outclassed by other £1k full sussers.

Highs
  • Super sleek frame design.

Lows
  • No rebound adjustment on shock.
