Looking into upgrading to FULL hydraulic brakes on my Rad Mini. Only issue I have is I need to know if it is an OPEN or CLOSE type circuit so I can purchase the right one. The brake levers are TEKTRO EL555-RT and TEKTRO EL550-RS. I looked up their specs and there is no indication of OPEN or CLOSE also emailed them and RAD. No response. Anyone know how to check or have the correct info?
