Scotsman and Westlander locomotives with 'tailor-made' trim.
We explain how Locomotive EBB works.
For starters you can use it to fit 4 different wheel diameters (including the 700c gravel). How to position it in this case is explained on the frame where guidelines are sandblasted that suggest the various positions according to the wheels used.
There is also another way to interpret this feature: that of adapting the response of the bike to your use and your riding style.
It is possible to vary the height from the ground, the length of the carriage and the saddle angle by orbiting the bottom bracket around a circle with a diameter of 17 mm.
The rotation of the index (that small black rectangle on the top of the movement) changes the response style of the bike. It is not something to do every day. It's a little like 'setting up' and then keeping it as you like, perhaps excluding the bikepacking week where you will prefer a setup suitable for the loaded bike to ride 12 hours a day.
I hope the diagram is clear.
If it wasn't, we're here on purpose to clarify.
