I have standard 113mm raceface ISIS BB's in both of my ATX 1 DHs, ones an earlly (less gusseting & different geometry) and the others a last of line with the drilled out suspension arms.
- the early one was at the rob warner exhibit at the henley river & rowing museum at the start of last year
I have the standard red anodized ac device on one of the rigs and a replacement (they still sell them) BETD device that is excellent (never lost my chain) on the other. I found the BETD device a synch to fit and adjust (though it comes with an extra bit - the bb circular mount - which you don't need - this confused me for a bit!)
any more questions fire them over!
