I recieved my new stronglight Impact recently and surprised at how nice in appearance it was. Then I turned it over to see the inside of the arms and noticed that they completely unfinished. I mean "casting pits from the mold". I haven't tried it out yet and it won't affect performance but it will appear dingy. That might be nit picking but I like my bike to look good. Those pits hard clean. For that I'm disappointed. I will probably at least sand the pits out before I install it. So far a little disappointed and thought people should know

Suitability for 7/8 speed? Your spec says CSA 9/10 but it appears that some folks are using these as replacements on 1980's road bikes. Can you clarify please?
Thanks for getting in touch.
The manufacturer recommends that it is for 9/10 speed. It may be possible to use this with other speeds, but I cannot guarantee the compatibility or efficiency if going against manufacturers recommendations.
Are these 110BSD if I would want to change the chainrings later?
Thanks for your query.
The rings are indeed a 110BCD.
