Product Information

Although given the limited advantage of the metal axles in tests so far I think I'll hold off until the HDBricks sample pack arrives and I can test those.

I compared my ball bearing train axles with the original LEGO train axles using cars that weight 685g. The use of 3D printers makes it possible to produce LEGO compatible components in smaller quantities and without the need for complex and very expensive injection molds. Before Ben Fleskes started to produce his BBB train wheels, this was the only and very expensive method to add some more steam engine realism to LEGO train models.Our wheels are designed to fit seamlessly within the LEGO system to cater for train MOCs that require larger (or smaller) driving wheels. They might have slightly higher rolling resistance than the old ones, but not as much to worry about IMO. Similar in design and size to the discontinued 57878 train wheel by LEGO, these wheels fit standard metal axles much more tightly - no gluing required! I'm more a Technic fan but long covid means I have too much Lego time and not enough enthusiasm for yet another Technic car.

The fixed technic axle drivers have grooves worn into the flanges where they rub against the rails in the curves. I think the former is likely to be more important, so we get the wheels rotating independently more easily. I suspect I need to 3D print some holders that have an exterior section like the Lego wheel holders do.

This is because the two wheels turn the same speed (same rotation speed), but they need to run different distance on a curve (the outer longer, the inner shorter), so the outer wheel will be dragged or the inner slipped. We have a large range of commonly spaced rods that fit within the Technic system, perfect for replacing your brick built rods. With LEGO® Train Accessories from Bricks to the World, your children can know how much fun it is to design a custom railroad from the ground up.
