Hello all,
I currently own a GT aggressor XC3 which I use casually on weekends just to stay active.
I mostly cycle on roads/cycle paths (generally good to ok terrain) and it's a great bike that has served me well over the years. Last year I put much thinner tyres on which made a monumental difference to my performance but now I'm finding that I could use some more grunt in the gears. Currently have (I think) a 42 top ring at the front and I'm running out of gear as soon as I hit 23/24 mph on any sort of downhill.
My question is: Would I have to replace both sets of chainrings for larger sizes to improve this, or could I just replace the front chainring first (obviously with the option of doing the rear at a later date if necessary)?
Sub Question 1: Would I have to replace the whole set of chainrings or can I replace individuals?
Sub Question 2: Would I automatically have to buy new derailleurs if I change chainring size or are they adjustable?
Many thanks in advance, and apologies to the seasoned amongst you who have probably known this information since the age of 9!
