The Marin B-17 (with a few tweaks!) can still hold it's own against most of the current 'Freeride' bikes.
I ride this bike on trails and downhills and it will still ride back up while the big travel boys are busy pushing.
With 6" of plush rear travel, if you were lucky enough to get the very early spec'd Fox Vanilla RX instead of the rubbish Shock Works later rear shock.
The original RST Hi-5's were shocking (or not as the case may be) and ran on elastomers with air damping, you had to be 15+ stone to get them to move. If you replaced with something better it made a huge difference.
The B-17 ran a beefier, longer rear swing arm increasing the wheelbase over the XC versions and improving high speed stability.
This bike was a revelation to me, as here was finally a bike that had some proper suspension travel for taking the big hits, not just 3-4" for the XC boys. It cost £1280 in '97 (or maybe '96, I've got the receipt somewhere).
It will take everything I can throw at it, especially with 170mm travel Jnr T's, but still manage a days XC riding (unlike me!)
But roll on the downhills....
