Recently got new single lock on grips (Ergon GA2 Fat) and I am trying to understand if the warning in the manual is referring to some real hazard or is just there because the legal department said so. The warning (page 3, step 4) says:
Ensure that the grip is completely pushed on to the bar. Failure to do so will create a safety issue.
While I could push the grips all the way on to the bar, that feels to narrow for me. My current lock on grips have an "overhang" of approximately 1 cm. Here is a crude illustration (the grip is the hatched, rounded rectangle):
I have used the bike like this for the past 2-3 years without any problem, however, now that I read above warning I am wondering if this is safe.
Is there an acceptable amount of overhang, or is any overhang cause for concern, as the manual states?
In finding out my bike fit in the past, I narrowed my handlebars by cutting of 2 cm on each side. Later I found that the narrowing was too much, so I simply shifted everything back a cm or so, creating this overhang.
80% of my riding happens as part of my day-to-day travels in an urban environment at moderate speeds, 20% of the time I use it as a road bike on tarmac. The bike is a Merida Speeder 200 with a straight handlebar and Shimano Sora SL-R3000 trigger shifters.
