I just sold my IP/CS-036 this past weekend. It was a fun bike but I'm not looking ahead to building another plus bike, probably a 27.5"x3.0" full suspension version. Peter has a CS-M04 frame that looks pretty good.
After two years of riding the -036 I enjoyed how well it rode but after getting my 29+ bike, I found the bigger tire size just made both my 057 and 036 bikes obsolete. The -036 has a steeper head tube angle that just made the bike feel twitchy and less stable on the fast sections, but it did climb really well, especially with the ability to control the suspension with the twin-loc remote lever.
I also have my 057 for sale, so if I also sell it, I will be looking at a new build. I will keep you guys up to date on what happens next.
I was a little sad to see the bike go but I think my next build will be even better. Goodbye -036.
