Have ordered primarily because of the design the lever. Am surprised how stable are the levers. Drive it with Avid SD7 brake bodies. Works fine. No Flex, precisely defined pressure point. The setting was done very quickly and easily. The (anyway actually superfluous) return spring I do not miss. The restoring force of the braking body is sufficient in any case. However drive very low friction Jagwire brake inner cables. The XLC brake lever is free of play to act installable and very pleasant. Before installing set up the reach to the personal needs! Conclusion: the brake lever and brake-called body interact perfectly. The XLC BL-V10 provides powerful bite, is meticulously crafted and precisely milled. Gripe: The brake cable can not be simply suspended, but must be re-threaded. How does it itches. One more thing: The relatively open design of the handle is very easy to maintain.
