Worked well for my kid. I concur about the need for spacer/shim for more mounting options. I ended up 3D printing some spacer/shim to be able to fit a dropper trigger. It would be nice if you could include a couple of extra shims with the bar.
These bars do allow for a perfect fit for kids with small hands. The only issue we have is that the spacer that allows for mounting of the dropper post thumb lever is a bit too close to the riders hand.It would help if the spacers were longer so the thumb lever could be mounted further way from the grip.
Thea are perfect grips for kids. My 4 year old struggled to shift gear in her new full suspension. There grips are so thin it fixed her shifting problem. Best grips/bars for kids ever
These have been awesome for my 6 year old! Huge improvement on grip for little hands. I'd highly recommend the upgrade for your kids.
