Rear drop outs
Off-Road frames (at least some) have horizontal dropouts. Race and Race Lites do not. I'm not sure if this change occurred with the model change, or this was by request

Cable guides
Early frames have bonded cable guides, and later frames are TIG welded. I believe that this change occurred with the introduction of the Race in approximately 1992

Front derailer stop
Until about '94(?) frames used bottom pull front derailers. The cable was rerouted via a pulley (not shown) to allow top tube cable routing. When this change occurred the cable stop was moved from the rear of the seat tube to the front right

Down tube gusset
Although rather hard to see in this picture, the down tube gusset is more bulky on the Off-Road than the later frames

Chain stay gussets
The drive-side gusset is significantly longer than the non-drive on the Off-Road frames. The non-drive is shown on the Race Lite as the drive-side is complete obscured by the chain rings

Chain stays
Off-Road frames had an extra bend in them (on both sides) near the dropouts. Race and Race Lite frames are straight

Mono-stay tube
The end of the mono-stay tube is not capped on the Off-Road. It is capped on the Race and Race Lite. (Note that the bike is upside down in the pics.)

That's a good guide, I have often referred to that archive on the original authors website:

The archive of Keith's secret website is still available too, here:
