Strengths: Nice clean design with a straight forward approach to a common bicycle component. Gives a true feel to how tight the skewer is compared with a creaky and awkward quick release. Could also slow down the thief that may not be carrying a hex key in their back pocket.
Weaknesses: None
Bottom Line:
The perfect solution to securely holding a wheelset in place. Not ideal if you need quick trail side access in a race, but perfect for those that need piece of mind.
