The Alchemy Arktos is an intriguing suspension platform, in that its chassis can be reconfigured to change the suspension travel with the change of the link and shock. In addition, the Arktos 135 and 150 iterations also feature the ability to run a mixed-wheel configuration. I’ve been spending some time testing the 135 MX, which arrived in with the 27.5″ rear wheel. I was curious about how it would ride as a full 29er, so the folks at Alchemy also sent the 29″ link and a 29″ rear wheel.
The bike has been fun to ride in the mixed wheel configuration, but based on the amount of travel and pedaling efficiency, I was looking forward to trying it in a full 29″ trail mode.
Reconfiguring the Arktos 135 from 27.5″ to 29″
Changing the suspension personality of the Arktos requires removing the linkage and swapping it out. The process is a bit time-consuming, so it’s not something you might want to attempt in the parking lot before hitting the trail. For 2022, Alchemy revised the link to incorporate a flip-chip, which should dramatically shorten the transformation.
There are quite a few bits to keep track of while changing out the link, so I took care to keep track of the pieces as I removed the rear shock and removed the link.
The process would probably go more quickly if one did it frequently. It can be helpful to take a few photos with a cell phone to keep track of the orientation of the bolts and placement of the washers.
Alchemy’s Sine Suspension climbs efficiently, so I was looking forward to hitting the trail with the larger rear wheel and noting the shifts in the bike’s personality. Stay tuned for the full review, and if you haven’t read our post covering our first impressions, check it out here.
