not really important. drivetrain will wear fast or worse chain will skip. it will be either busted knees, concussion, tooth loss, sprained ankles, road rash, crushed nuts or all of the above. :D j/k. keep your chain line straight. :thumbsup:

just imagine every sensitive part of your body simultaneously (and at the speed of light) slamming into your handlebar/fork stanchion/stem when you throw your chain....all the while clipped in and ending in a slow speed 1/2 crash/endo on your side.....if you're lucky....;)

it feels like someone tieing one end of a rope to your seatpost and the other end to "immovable-stationary-object" of your choice......it's sudden and sucky....






or....as stated above.....you wear your chain/ring/cog out quicker......but why risk it?

Measure the center of your chainring from the center of your seat tube up in front and try to match that value with the distance of your cog from the center of your rear dropouts. The closer you get - the less premature wear and tear and risk of derailment - and no one likes anything with the word premature in it!!!!!!!!!!!!!!!!!

Or just put the chain on, stand behind your bike in the workstand, and look at it to make sure it's not "bending".
