Help! Impossibly small hands!

[Roadtrip]

It's a Trek Pure with SRAM MRX "Twist" shifters... me don't like due to size and acerbated by my larger hands... tho I think I know why... see below.

It's not necessarily the twist shifter itself (even tho I prefer the standard type shifter), it's the crappy setup to begin with. OK, they prob ASSUME your on this bike and most likely not doing to be shifting much. WHY give you 21 gears if they assume you won't be changing.

Honestly, I'm not sure what part I've been having issues with... I hate the shifters. Trek seems to have put the cheaper version on this bike. the version I find on Amazon looks totally different-- better-- longer "grip" portion. Plus the shifter for rear derailleur still has seven or eight "clicks" even tho it's a triple in the back-- so-- click-- click-- click-- ok-- I'm finally there. It's like they got an overstock on right shifters and someone in accounting said use then, just change display 1-7 to 1-3. In order to go into my big gear for flats I have to mash the thing well above "1" in order to get it to change gear.

Rear derailleur is a Shimano Acera that seems to need constant tweaking and last night nearly killed me on a hilly ride when it WOULD NOT let me change down a gear. Not to mention it often likes to buck me so hard it has more then once threw my right foot right off the right pedal when changing gear.

Ended up riding as far as I could and felt like I was going to cough up a lung-- ended up pushing my bike up the last hill. Enough to make you want to leave the bike at the side of the road and just walk. Nothing like grinding away at JUST barely faster then you can walk because when you try and shift all you here is grrrrr grrrrrr grrrrrrr and chain stays right where it was.

Really need to learn how to make these adjustments myself.

Sorry for the rant!!
