Travel normally is 10cm/4". Tuning linkage come up to 12-13cm. And if you have a good damper, it feels quite modern and is definitely enough if you don't do downhill stuff. But that would also require modern disc brakes and no v-brakes
I don't think, you can bottom out a rear that is set-up well!
I just finished the upgrade to a BETD and one of the first DT swiss air dampers. Had a test ride yesterday in the backyard after 6 hours of turning new bolts, turning fitting screws, filing out the BETD. Felt like a curse, so much that did NOT fit...
edit: Now for some pictures. Still around 13,1 or 13,2kg. But now 130mm now front and back. And adjustable seat height.
edit: A german fella told me that this specific linkage has 144mm. Pew, that could explain the too sharp steerer angle!
As you can see, there is almost NO room between the damper and the linkage. Filing ahoy... This bike is full of constructional flaws: Seat post does not allow to lower the saddle. For installing a new damper you need kid's hands as there is no room for fingers, bushes AND the damper on the upper screwholes. And so on. But I love it.
