Is there any problem in changing the large front cog on my rockhopper pro from a 44t to a 48t? Looking for a little more top end speed when commuting?

    you might need to adjust the height of the front mech to accommodate it, that's where my experience ends

    Most front mechs do not like a 16 tooth jump to the middle ring.

    Rather than increasing the chain ring, do you have scope for fitting a more agressive cassette? I have a 44t chain ring coupled with an 11-23 cassette, which for me is meaty enough. A new chain at the same time would be recommended.

    it is most likely to have a 11T cassette on it already.

    It does already have a cassette with an 11 tooth small ring! I am still running out of gears on some of the longer downhill stretches on my commute on the road! Was looking for the easiest cheapest fix!

    44x11 is over 100". Should be good for 40mph, if you learn to spin a little, after that you'll go faster if you freewheel and tuck, anyway!

    The "easiest cheapest fix" is to work on your technique :-), you'll find that you ride more efficiently at "normal" speeds, too...

    Cheers,
