Recomendations for dual chainguide system for 6.6
Have my eye on the E 13 DRS.
The DRS will work well on the 6.6, it is a good option as you can use it on frames that do not have ISCG tabs. I run one on my Uzzi VPX, and it works great, without any issues.
Blackspire Stinger. Light, cheap, works perfectly even for bike park or DH, no chain drop.
