i took a quick "break" from work to receive the parcel and unpack it to have a look. i couldn't resist.PeteC":g62054ft said:
i'll be doing an in-depth analysis of the two later this evening if time permits. again, as above, i'll reconfirm later. but you're right, it looks MUCH larger. :? i THINK it was advertised as 18"? regardless i didn't buy it to ride it, strictly as a donor, so no skin off my back if even bigger than initially thought.mkozaczek":g62054ft said:
okay original advert had:
just to add, from quickly holding up the swing arm pieces to compare earlier, upper and lower looked the same length between the two frames.
so advertised as medium 18" but i guess it's a 20" from the serial number, is that correct???

Yep. And the 'C' denotes that it's a 'Cunningham' Mantis and not a 'Redline' Mantis---which I think most people will think is a good thing. Can't remember where I read that, but I learned it from lord google at one point.
By my math, the actual C-T on your blue frame is a tad over 22". But like you said above, it doesn't really matter. As long as the lower arms are the same length, you're golden.

so had a better look and i think the rear triangle are practically identical, with some slight tolerance variance due to workmanship.
notice the gusset on the lower swing arm is shorter from the larger frame. :? canti studs are slightly off on the upper swing arm.
looking at the main front triangle, you see that the larger frame shock mount is higher, obviously due to the higher top tube, but also farther back. while the smaller frame the mount is more forward. so it seems the mounting point would be on the same arc in relationship to the rear drop out pivot point, just one having a larger radius angle than the other. hence why the rear swing arms are of the same lengths.
curious if that would affect how the suspension performs and if it changes any ride characteristics.

yeah, shame the blue one wasn't my size. i could have just built that up and be done with it!
anyway, gonna build her up and give her a whirl before going down the path of strip and repaint.
just need to source an appropriate 1" suspension fork. :?

the ol' fleaBay is a always a good source for 1" forks, of course. Yours came with a 1" Mag21 SL Ti, FYI. Sold it before you acquired the frame, as I recall. If you find one in the US and the seller doesn't want to ship to Canada, I'm happy to be the middle man again.
