Oh, and where are you based (I'm in Melb).
By the way, I saw you mentions kids.... I'm doing the opposite... kids have arrived and now trying to find my way back into MTB (XC and DH as I alluded to in the post). They are young now, but I'm aiming to get my legs and lungs back into some kind of shape as to keep up ;-)
Gearbox made in the way it is important to go 2x5,2x6,2x7,3x6,3x7,3x8, to not have big difference in gear ratios. This does not making my ride any more fun, but in fact quite frustrating, as sometimes it is just turns into constant switching with left and right hands to the point when I am no longer fallowing which gear is which and have to look onto actual shifters.
moorey, I will opt for 36 if you don't mind, mate. Thank you very much.
I am in Gold Coast. U208.
As to my reasoning on 3x->2x it is simple. For where I am riding - it is really steep, so I can only manage 1st chain ring(22t). And when I am cruising along the city(plenty of low hills) I have to constantly shift in between 32 and 42 rings upfront.
Moorey, it is 3x now, and I am switching to 2x. Was thinking of getting one of chin rings available on internet, but realized separate ones are narrow/wide design. If I am not wrong this N/W chain rings are for 1x system. So I actually need to find something dedicated for 2x. So much new information for me... overwhelming
