I picked up a wrench force wrench which wasn't all bad. Mind you, it was to replace the really crappy wrench that came with my 100 dollar evo tools kit...

The chain whip that came in the tool kit worked out alright for me though. Got my cog on well enough that it didn't fly off on my ride tonight...

Speaking of which, my bike is finally dialed in to where it feels totally comfortable except for the less than ideal but not crappy seat. Took a fork flip and new cog, but it all feels awesome now
