NGeco Jcob

Select this power meter to upgrade your current Jcob cranks to ride with dual-sided power. Simply remove the crank spider, install the NGeco and you are good to go!

Note: due to constructive restrictions the NG and NGeco for Jcob will only work with Jcob cranks that have the 3 bolt interface.

Just released is the Shimano 4-bolt chainring version.
