Id have to agree with Rod on this..
I cant see this working well for DH.
If you’ve ever seen how much a chain moves on a decent dh run, it jumps up and down considerably. Hence why e13, mrp etc have fully enclosed guides to stop this, and also why a lot of the time we are running a pretty high chain tension.
Ok for tame xc/am but for dh i cant see any benefit over conventional dh guides. I even use a e13 lg1+ on my 4” because similar setups like this wern’t working for me over rough fast stuff.
ps.. Nice frame/forks and wheels. Good to see something a touch different!
