XT flow-through
The set of bottles on the left illustrate how fluid flows down through the new caliper, unlike the old caliper, represented by the bottles on the right, whose bleed and intake ports were both on top. (BTW, the left bottle set is inverted; the through-port is below the pistons.) Photo by Lennard Zinn
