Thanks Joe and Andrew.
The bike currently has a 120mm stem on it, which is way too long for drop bars.
I have been considering fitting one of these:
It's a 90mm Kalloy "Mountain" adjustable stem - (The Nitto bars need a 25.4 clamp rather than a 26). I'm just a bit concerned it mighty flex and/or creak.
I suspect I may need to fit a steerer extender, but I'll see how things work with the adjustable stem first.
Good call re not wrapping the bars until I'm sure I'm happy with the fit.
I'm also thinking of fitting Kellys Take Offs and downtube shifters rather than the bar end shifters.
However freight to Australia makes the Kellys option twice as expensive as bar ends, and I'm not sure it's worthwhile.
