I have a Lectric 2.0 ST ebike and it seems it is hard to find a good replacement for its Tektro MD-M280 calipers. I was wondering if the Tektro MD-C550 could be better as this model is dual piston but I do not exactly know how to verify this.
a) Could MD-C550 be a direct replacement? b) Are there any other models that could replace the MD-M280
My goal is to have a better and more reliable braking system while minimizing the number of changes. Therefore, my first tentative is to find mechanical/semi-hydraulic (cable actuated hydraulic) calipers to just replace the original MD-M280 and left everything else original. I feel this could be very helpful for the maintenance of the bike. For my bike the volume of the calipers could be critical but I do not mind changing rotors.
I wonder if this is the right place to ask this kind of questions. If not, please forgive me as this is the first time I make a question in this site.
