The one thing I'm not over the moon about on my old faithful Giant Sedona is
the gearing. With a Shimano TX-70 24x34x42T triple I find I'm spending
nearly all of my time in the top cog and the top 3 gears on the rear. I'm
having to coast down lots of hills when I've still got heaps I could be
putting into it plus I don't think putting great gobs of torque into those
tiny little rear cogs can be good for their wear rates. So I reckon the
current 42T would make a better middle ring and a 48 or even a 53 big ring
would suit me for the 99% road riding I do these days. (I tend to average
around 30kmh on the flats and 25kmh overall sitting on around 80rpm on my
daily 20-25km ride.)
But what do I need to shop for to find a bigger triple? The TX-70 is
apparently a Tourney so something around that quality and price is what I
want to go for but I'm a bit unsure about compatibility with the existing
crank etc. Is there a part No anyone knows would suit me off the top of
their heads?
