I've got an absolute black on the stache....I know there was a boost option with an offset? Worth investigating maybe?
I can vouch for the quality though.....lots of miles done, on its third(?) chain, no signs of wear and no chain drops at all.....would buy again!
And I can vouch for the absolute black, they are good I've got them on my road and cross bikes, they have a little wear in period where they have a very slight noise, but 1 long ride should remedy that.
