My groupset is a full and original Dura Ace 7702 9spd groupset. The chainrings are original, and 53/40 and would like a smaller small ring to make the hills a bit easier! What options do I have please without compromising the current system?

53/40 ???
are youconstantly reavalueating the situation and altering the perceived parameters accordingly0 -
My apologies, I just re-counted it - 39T, sorry :oops:0

Sorry to ask again, but is there a smaller (than 39T) inner chainring (2 ring setup) available for this set that I can use please, or what more compact chainring setup would you advise please?0

You can go to a 38 tooth front ring and that's it. Nothing smaller will fit(or is even made - because it won't fit the bolt circle).
Compact crankset is the only way to go lower than 38.
Well, there's always triples, if you care to go that way.0 -
Thanks for the reply Dennis. I have now got a 38T coming, small change as it is it might help me a little, thanks.0

A larger big sprocket on the cassette? You can get shimano 9 speed cassettes with loads of combinations.Summer - Colnago C40
Race - Wilier Alpe D'Huez
Winter/Commuter - Specialized Tricross0 -
Now that is of course soooo obvious when you mention it :oops:
Thank you, I will look into that as well next.0
