The "daytime running lights" that is similar to the optical fibers in current car design, is a nice design idea and brings a certain recognition factor in the dark. During the day, but it is relatively weak - the direct beam daytime running LEDs of Lumotec are clearly noticeable.
Unfortunately Trelock, the attachment of the two headlamps designed completely differently: The 872 does not fit the headlight bracket of the 690 - as I have a fork with special headlamp attachment (SR Suntour), I also had to get another holder to the mount 872 to.
