R.3 P-QR seatpost with anti-theft protection
The by,schulz R.3 P-QR seatpost with anti-theft device allows you to adjust the seat height conveniently and without tools using the quick-release function.
In addition, your seat post has a combination of safety devices to prevent unauthorized removal. The stop ring screwed into the end of the seat post in conjunction with the aluminum reduction sleeve ensures that the seat post cannot be pulled out of the frame. This also ensures that the minimum insertion depth of the post is always guaranteed.
The R.3 P-QR with pull-out stop and anti-theft device was developed for bicycle manufacturers for original equipment and is not yet available for end customers.
Hartje is one of the first manufacturers to install the R.3 P-QR on the QIO.
| Material | Aluminum AL-6061, AL-6066 |

If the safety pin is damaged or lost during removal, it must be replaced with the original part!

The R.3 P-QR seat posts can also be installed without this safety feature. However, the protective function is then no longer provided.
