Hi, there
When i was assembling a set, i got a question.
I'm asking help to solve my curiosity,
1. This product, 57518(Technic, Link Tread Wide with Two Pin Holes) is hard, didn't bend easily even if i give it strength, and i found it, made of ABS material.
2. And next part 3873(Technic, Link Tread) is softer and and was bent easily compared to 57518 when i give a strength
3. BrickMania Track Links
just added because look same material as No.2, Part 3873
I wonder why Lego made first one hard and second part light and soft
is there any difference in purpose or usage between the two parts?
and more, wanna know the raw material of 3873 briefly
Need Help you Guys
Thank you and have a nice day~
