Press Release: Cascade ComponentsIn collaboration with Cannondale, Cascade Components is excited to announce the release of the Jekyll MX link for use with 27.5” rear wheels on 2021 to current frames! This linkage is designed to preserve near-stock geometry when swapping to a smaller 27.5” rear wheel. BB height and all the various angles are preserved. The only real difference is chainstay length and wheelbase are effectively 3mm shorter.

There are some minor changes to kinematics that also occur when using this link, however, it is more intended to preserve geometry than create a different suspension feel. That said, the link does increase both travel and progression a slight amount. Kinematics are size dependent on this bike. Across the board progression increases by four percentage points meanwhile travel increases by about 9mm. Note progression with the 29” link is between 12% and 20% depending on size. This is a little more modest than other Cascade links because this is intended to deliver a similar feel to the stock 29” link. With the rolling properties of a 27.5” rear wheel, we and Cannondale believe these changes make it roll through rough terrain similarly.
Another change worth mentioning is the axle path. In moving the rear axle down to accommodate the smaller rear wheel, a more rearward axle path is created. It isn’t a massive change, but by end of travel, the rear axle has moved about 5mm more rearward than it does when using the 29” link.

If Cascade made a 29" link, which they wouldn't, I doubt they would stray far from 4% more progression. Bikes that are too progressive don't ride well. Also, the notion they didn't design this "to increase progression at all" is plain wrong. They are perfectly capable of designing these links to perform however they want, it is no accident this mullet link produces more progression.
The Jekyll has no geometry adjustment, Cascade tends to be in the business of filling useability gaps in bikes like that.
This might work
