Brompton owners

Don't forget to cable tie the folding rear triangle to the seat tube before installing a Brompton in a cycle stand ! at the LBS that I worked at all Bromptons were dealt with this way (and before doing bunny hops up and down the shop floor)...most Brompton owners were unable to go through the complex engineering required to fix a puncture on their machines.

Is it not possible to replace the block with the newer one that lock the rear triangle?
