Who has them? Do you wish you didn't buy them? I'm trying to justify buying two plus a bit set. Right now I see it as an investment in myself because I will prevent myself from breaking something in the future which would then cost me money. Example: carbon handlebars: $170. Torque wrenches and bit set: $70. Total investment: $240. Cost of replacement handlebars if I over torque the stem: $170. Total investment $340. Pretty easy to justify it no?
