Jeffsy – that’s a neat bike!!!
On my cheap hardtail and full suspension bikes (27.5 and 29) I use Mudhuggers on the front. Can’t fit the rear mudhugger on the full suspension so…
There I use in winter time a TOPEAK DEFENDER. Mounts to the seat tube. Means no dropper in winter time…
The mudhuggers are the better option – if they fit. To check on the back: release the pressure of your damper. Push the bike all the way down. Is there still “plenty” space between the rear tire and the frame? On my bike: no. Nearly no space. Mudhugger rear won’t fit.
Rear mech of the Jeffsy looks similar to mine. Fear that will be the same problem on the rear.
Topeak Defender, Mudhugger, hardtail / full suspension: never lost one.
Topek Defender mounting on the set tube: bit tricky in the beginning to understand the strange “universal” clamp. Had to read the instructions. Now it works (ugly beast so). Like the mudhugger much more.
