I purchased a bare raven frame, one of the first to arrive from the Factory. Not having expected to have a BB installed in it, (it was branded: “Racer professional”), I never made a fuss about it, but I suspect the BB in frame was factory installed, since I didn’t believe SJS would fit something of such dubious quality. Mine was probably never taken out of the box at SJS and passed straight on from container to courier.
Anyway, I’m sure that SJS will deliver a high quality assembly with a perfectly straight chainline. But if you purchase a bare frame, like me, you might want to check the BB.
By the way, I'm off for three months, hopefully for a bit of cycling in China as well, so hope to be back on the forum in February.
Enjoy your new bikes,
Cheers,
Stijn
