Clamp Lock for Dolphin & Beluga STD/PLUS

qualisports 57mm clamp lock is very sturdy w/ innovated locking mechanism. There are three different sizes available 52mm, 57mm and 63mm. Unlike "How to install" Video above, only 52 & 63mm come with wrench tool so we can simply destroy the volt on purpose since most thief carrying allen tools but not this type of specific wrench thats thin enough to go through the gap of clamp. Unfortunately, 57mm does not have this option but anyone with allen tool can loosen the seatpost while it's key locked. At least noone can open with with bare hand. but no thief will try to steal anything with bare hand in the first place right!? which means it's just same as other wrench clamps (without quick release lever) and hard to say it's worth the bucks. I guess they could come up with better idea and keep the price or leave as it is now and lower the price.
Yet no doubt they got the best customer support.
