In our opinion as much as possible. However, aging can also be functional, meaning that compatibility with new standards or with a type of use that was not foreseen at the time of purchase is lost. All Locomotive frames are designed for use with the telescopic seat post.
For Scotsman and Midnight Express it means having a fantastic vehicle even for 'bad' use. The difference in driveability on the technician becomes impressive when you switch to the Westlander with Dropbar geometry .. a true monstercross that, with a little set-up, tackles routes that very few other frames with racing handlebars can afford to take into consideration.
It could happen that you will never use them .. but it could also happen that one day you will want to mount a telescopic post. These frames are all set up already, so you won't change bikes and we poor bike makers will all fail.
