Well, I guess you are referring for the Kauper system when saying hidden parts inside the bar.With this system all parts are outside and easy to inspect without hidden wear-points inside the bar like with other systems.
I never had the Kauper, but the benefit of only adjusting one point and altering both steerling lines,
instead of adjusting both steering lines seperatly,
sounds appealing to me.
So, I guess your system does not have an urgent need to inspect the lines regularly,
so was it more an ideology decision because you wanted it to tick that box?
Would your Max Bar offer clearance to route lines threw the bar to install a different system, or is the insert blocking the way?
Thanks
