no, you don’t need to go on a diet to ride the Bergmeisters!
A few people reported that they got flat tires on the Bergmeisters, even though the PSI was in an acceptable range.
It seems that we are to blame for some of these flats. It turns out that our Bergmeister design is not optimal in that a sharp edge can occur around the inner tube’s valve stem. That can happen if both rim halves are not perfectly matched (when screwed together).
For the next production batch we will slightly modify the design, so as to avoid this issue altogether.
The good news is: there is a VERY SIMPLE solution for all of you, that are currently riding the Bergmeisters. You will no longer experience any accidental punctures around the valve stem by using a silicon o-ring. We have tested it and it works very well (See picture below).
So what do you need to do? Send us an email to [email protected] with information on:
a) how many Bergmeister sets do you have
b) first name / last name
c) phone number
and we will send free of charge the silicone o-rings to you. Please note that these o-rings can be re-used, so do not throw them away in case your inner tube has been nailed.
So our apologies for those flats. We will start shipping out the o-rings from Tuesday onwards.
cheers Timo & Jeff
