I’ve had a set of 2011 model Vengeances for about a year and have been really pleased with them. They’re the HLR model, 160mm travel with the allen key dropouts, not maxle type.
First impressions were very positive – finish is fantastic, all the adjusters etc etc have a very definitive feel to them and each click does something.
Once they bed in they’re nice and plush, really stiff and so far have proven to be really reliable.
Only downsides are the lack of maxle and they’re quite tall compared to equivalent fox etc. Both of these were addressed for 2012 though so if you buy new you should be OK.
There are some good reviews by stw, bikeradar and pinkbike if you haven’t already seen them.
I really like the brand and their new forks are coming with some nice bits and pieces – one piece crowns, “kashima” etc so I’ll probably stick with them for my next set of forks and probably a vector hlr air shock.
If you’re in the lakes give me a shout and you can have a look at mine.
