I’ve gone from an SB66 to mega tr.
Mega tr pedals better, jumps better, feels stiffer and structurally more composed on big hits.
SB66 is 150mm, mine had a vivid air, in terms of eating the rough stuff, apples and oranges.
Mega tr is a fun bike, good for the “play” rider. By play i mean someone who is looking to makes shapes in the air, manual and gap everything in sight, something that is involved.
As a actual trail bike, the tr is most probably a bit heavy and not as good at pedalling as a proper trail bike like a sc solo for example, if you’re after a mincy comfy sofa when you are riding trail centres and tame stuff, it isn’t that either.
Mine rips, i love it, it’s like a big off road BMX.
