Polygon Siskiu D5 Goes From 27.5 to 29 Inch Wheels

Note: I incorrectly referred to the stock XCM fork as an XCE.

I love riding my 2021 Polygon Siskiu D5, except when the wheels get hung up on a big root or other obstacle. This is particularly annoying when climbing. So just for the fun of it, I tired my spare 29-inch wheels with an older set of Schwalbe Rapid Robs. The rear wheel fit just fine, but the front wheel got hung up on the tire nubs on the 27.5 SR Suntour Epixon air fork. On a whim, I tried the stock SR Suntour 27.5 XCE. It worked! There was not a lot of clearance, but there was enough to prove the concept. So I now have a 29-inch fork on order, details to be revealed in a later video.
