Well I always try to give a choice when there's a question like this. But there's really only one answer. Fresh from the dehydrated prunes shed (the history of Klein is interesting) there was only one grip which came on the first Klein MTBs...
Good fail safe grips, and similar in some ways with the ribbed design to the Klein grips themselves. It depends on what you are trying to achieve with you bikes, comfort, looks or originality? obviously they are mostly personal choices.
Early Kleins were only ever specced with Grab On MTN-1 grips (unless Campy Bullit equipped), then their own Klein ATB (Instinct) grips from '93 onwards, they never came specced with ODI. Klein grips (sometimes wrongly named Death Grips, which were their tyres) pop up for sale now and again, you'll just have to keep your eye out for some and the original Grab On grips can still be bought, link here: https://www.sjscycles.co.uk/handlebar-t ... r-sleeves/
