Machined pistons
I'm really enjoying my XB4 build thus far - this thing is a tank! However, I must admit, I'm a little disappointed in the shock internals and pistons. These molded pieces are not what I would consider up to XRay standards, there is a lot of blow by with the pistons for example.
With TLR & other manufacturers releasing new machined pistons, shock internals & x-patterened o-rings, as well as coated shock shafts - I hope XRay soon offers the same.
On my wish list - 1.6mm & 1.7mm 2-hole pistons!
(side note - I tried to drill out some of my own pistons, but again, there's the stock part blow by and the holes came out a little bit oval-shaped due to my unsteady hand).
May have to order up some Avid 2+2's!
