Yer right, you have to add the spacer. In the crown there is enough room in a 100mm lefty to fit a 29er in there. It does reduce the travel to 80mm as stated, but it’s going to be a x-country thrash bike and that’s enough for me (I’m seeking out a 140mm FS for all day riding and getting rid of my 29erSS as I think I’ve done enough SS’ing for a while.)
The seatpost in that pic is fixed length, I’m not going down that route I want a separate seatpost.
I’ve had my lefty from new, it’s been serviced twice in that time and it’s been an excellent compliment to my riding. It’s never failed me, has always been lovingly looked after, is a light alternative, has never twisted and most of all.. it makes me smile.
No idea what to do with the donor frame, maybe I could stick a fixed fork on it a’la badboy image, we’ll see, as is it’s going to be a bit of a wrench to pull “old faithful” apart.
