Hi
I've bought recently a set of 29er hoops on 240s hub.
Unfortunately previous owner removed stickers from rims all what left
is min/max pressure chart [img]

Any ideas? External 24mm internal 18/19mm
Yellow and black makes me think Mavic?
also 'old-skool' 19mm internal sounds mavic-esque. Something like an XM ?19 maybe?
Not sure if mavic decals are stickers or not though.
Never seen such a sticker on a Macic and imagine it's unique to whatever brand it is.
It is definitely not Mavic or DT, I'm looking everywhere but can't find it
Could be a sun ringle rim?
Superstar sentinel rim?
Given its on 240s its probably a lightish rim unless the previous owner was mental. How accurate are your measurements? My guess would be a Pacenti from the look. They have terrible graphics that don't last well so wouldn't surprise me if they got binned off!
