Once again I've hemmed and hawwed. i've got a set that takes I think 8 rechargables. Useless.
Adding to my upgrade although NOT to my FX is a set of rechargable LED Lights to the tune of $215.
I'm not putting them on my FX because I usually don't ride that rig at night.
I'm gonna put the high priced lights on the 4300! That's what I'll ride at night. The roads here suck! I'm not gonna ride my FX on crappy roads AND especially at night.
Summer's coming....hot and humid. 4300 + lights +potholes.
Oh did I forget, deer, possum, racoon etc...etc........
I have a Blackburn X4 that I use that is nice and works great on my bikes, CAAD9 or Trek 7300. Plenty bright and last 3 to 10 hrs per charge and charge in full in about 2.5 to 3 hrs when drained.
