I bought my wife a Kona Four a few months ago as she finially agreed to ride some really light trails / roads with me. And as she got a bit more into it, I upgraded a few parts trying to make her life easier (the bike original weight 32+ lbs while she weight 105lbs!). Now while I see her ride ok with the bike's weight, its seems really tough for her to carry/lift the bike and walk through the more dangerous sections. Any more ideas on how to lighten her bike wothout costing a second mortage? spec and pic below:

Not gonna happen, I am afraid.

I would get SLX crankset, on ChainReactionCycles (~$110), and put aluminum granny from XT. That would be ~860g total with 44. You can put extralight BBG bash instead of 44 (~$15), so it will be around 800g total with BB. Then I will get the 11-32 XT cassette (~256g), about 80g of savings for about $50 on chain reaction.

Then you should get Halo bolt on skewers ($10), instead of

QR, you will need allen key to remove the front wheel, but it is actually faster. That will save you ~70g.

Seatpost and saddle sounds like a boat anchor. But saddle is a very personal choice. Thomson stem and seatpost would not be a bad idea anyway.

Excellent bike anyway. Under 27 pounds it should not be a problem with weight.

the seat and post weigh a lot...and so do he pedals, but IMO, I would get her a nice set clipless shoes and pedals, that would make a MUCH bigger difference than dropping 1 or 2 pounds with that money, and I also do not think it is do-able to drop ~3 lbs with under 200...go luck with the weight weenie-ing :D
