Yes, the cams can be reordered individually (left, right and front). Spare parts such as brakes, seat, handlebar and steering wheel can also be ordered individually.

Yes, it fits perfectly. I myself am 170cm for 65Kg, have had a Snowracer since I was 10, and am still a super fan of Stiga, for me simply the best sled anywhere, I can only recommend them! Now we have 3 Snowracers for the family, one of them is still my old Snowracer Classic, now 20 years old. I can also ride together with my son or daughter (10 and 9), of course it's a bit tight, but the sled is super strong and holds both of us without any problems, we just did a full moon run in Val di Campo (GR) tonight, super fun!

Difficult question because the second grandchild is 4 and I don't know if he uses it yet. But the older one is 8 and loves the device immensely.
