huh. if youre riding a cross check, you arent worried about weight, so id say find a more comfortable place to put it and ride on. i like having the most lock i can carry, short of the krypto chain.
i hate getting my bike stolen, so ill always err on the side of beef...that and im a clyde, so a 3lb lock isnt going to affect my auw drastically
what does your gut tell you?
