I have owned a few of the bikes you mentioned and one you already have. (transition BR/DB, UFO, Intense SS)aye-aye said:So i want something ideally with :
a bit more travel (but not too much, i like to feel whats going on down there)
short (sub 17" )chainstays
slackish headangle ( 66 deg or slacker)
low BB (14" or lower preferably)
sub 11 lb frame weight ( including coil shock)
stiff rear end
Here are my current possibles:
Knolly Delirium T (stiff and reliable but heavy and a bit too steep?)
Intense SS (light and poppy but not a stiff rear end?)
09 SX trail (looks perfect but can't buy frameset in UK and reliability unproven so far)
Nicolai UFO ST (adjustability and great geo but single pivot and weak chainstay issues?)
Transition Blindside (like the geo but too much travel?)
Transition Dirtbag (tough and chuckable but BB too tall and a bit steep headangle?)
Corsair Maelstrom (good geo but complicated and reliability unproven)
for what you described i would go for the Nicolai UFO ST. it is amazing. incredibly stiff rear end (no chinstay issues i know of) and it fits everything in your criteria. It feels exactly like a longer travel BR (i sold my BR to get a UFO). out of all the frames i would say it could handle the most abuse and be the lowest maintenance. The adjustability is awesome. It is the bike i took to whistler and felt it handled everything perfect. it jumps really good but still has enough squish to handle the gnarly rocky stuff. mine weighed 37 pounds with single ply tires.
the transition DB and blindside also are good options though. little lighter too.
The corsairs are very sick. have a few friends who ride them. only downside is the pulley especially with the front der but not too big of a deal.
The other good option would be the new intense Uzzi.
