These pegs are extremely well engineered, from the shape of the foot platform to the satisfying two-stage ‘click’ when opening and closing them.
When not in use, you’d hardly know they’re there. When you need them, just tap with your heel and they spring out. Great for kids, since it stops them from putting their feet where they shouldn’t be (driveline, derailleur).
For the price, these are a no-brained purchase if you think you’ll ever have a passenger on your GSD.
