Sorry i'm a huge noob when it comes to tools, what would be the incentive to purchase the tw-1 if the tw-2 covers the same range and then some. The seatpost on the slc01 says to torque the two bolts at 5nm and the other at 7-8. If i went with the tw-1 would the 7nm max that it can torque at be sufficient or should i get the tw-2? Thanks for all the help. I'm trying to get everything on amazon if i can since i have a couple other things there that i need to purchase. Might just go with these hex bits since there shipped and sold from amazon instead of a 3rd party through amazon. There 3/8 drive but from my understanding they should work.
