Blue Rabbit : I have different experiences with 601 Mk4 - this is my third Liteville frame (Mk1 cracked at headtube gusset after 5 years, Mk3 cracked at derailleur hole on chainstays) and the worst if I look from construction and reliability perspective (although it goes up and down better than Mk1 and Mk3).
All users of 601 Mk4 I know personaly, have or had problems with rockerarm - bearings are moving (wrong design and tolerances......). Liteville gives you new rockerarm with snaprings (but also this version doesn't work always - if I remember correct I am on my 4th rockerarm, repaired/remachined chainstays......).
Mk4 is the first 601 that I would not recommend to my friend.... It is just unreliable - I have my Mk4 almost 2 years, first year I had constant problems with frame and also
Syntace wheels. I have replaced them for DT350+Ex511 and now for a few months my bike is finnaly working without creaking and other problems - I hope it stays like that. I really like how Mk4 rides
I hope there will be Mk5, otherwise my next frame won't be Liteville.
Wow! Personally I do not know other LV Biker. I am for sure not a "power user", making only about 50.000 depth meters a year, no big jumps, with only 75kg weight. Alltogether I am not using bikes extremely hard like some of my friends, who always have issues no matter what brand the bikes are.
The "play" from the bolt through the damper bearing is technically not bad and can easily be removed (e.g. minimal knurling the bolt). Some tolerance here is better than to little tolerance.
I also had once a loose damper screw - took some Locktite to fix it and greased the whole assembly well. No rockerarm problems at all so far, works very smoothe. (I 'll probably make a video, of rockerarm on the trail for damper adjustment / tuning. If so I can post it here)
Syntace rear hub the toothed wheel / free running was scrapped, got a free replacement within 2 days. No more issues then so far.
Anyway, I always take a look around my bikes when biking intensively, making sure nothing loosens - that happens now and then with any bike, specially Enduros being shaken heavily down the trails.

Da sind Probleme mit einem Bike beschrieben, die sicher nicht häufig auftreten. Das sind aber keine Sachen die ein MK5 rechtfertigen, so nach dem Motto: " ... in der neuen Version haben wir jetzt einen Sicherungsring an der Dämpferschraube ... "
Klar, 29" wäre ein MK5 - alles andere wäre auch Quatsch, sofern es entsprechende kinematische Anpassungen der Raderhebungskurve etc. hätte. Nur so 29" wäre enttäuschend, weil ich das ja jetzt schon aufbauen kann. 29" würde ich allerdings nicht als Verbesserung bezeichnen, sondern als Erweiterung. Ich bin 29er gefahren, es war anders und auch gut, aber nicht unbedingt besser. Hat alles seine Vor- und Nachteile.
Detailverbesserungen für das MK4 liessen sich als Upgrade vermarkten, so dass auch die "alten" MK4's davon profitieren könnten.

... Seit ich das MK4 fahre, hatte ich nie mehr Rückenschmerzen bei langen Anstiegen.
