Previously posted on another Forum but getting a lot of conflicting information. I know I should have used a torque wrench, but you live and learn... Is it very easy to overtighten the crank arm bolts? The only reason I am asking as on my geared bike there is around 4mm of taper showing on the drive side and 2 mm on the other? I am worried that one side is "too far down the taper". I used the same tool as pictured below, its around 20cm long, I do have strong arms too! I'm using a Campag Veloce 111mm Italian threaded BB and Campag Crankset. If it has been overtightened, does that mean new crank? I take it the bottom bracket will be fine? Here are some photos, it doesn't show the differences between drive side and non drive side very well. Thanks in advance for any advice.
