I've use something similar to this in my truck tires works for a little while then tires seem to go out of balance again. Don't thinkI would put it in by bike.

 

well...........if nothing else im pretty well convinced it cant hurt to put em in so ill do that tomorrow. thanks for the input guys

 

well i put em in my frt tire and see an improvement in the ride. maybe i shoulda asked who has installed em without losing thier friggin TEMPER! damn tedious install, v stem clogs wore my finger out thumpin the side of the tube ta keep em flowing. had the stem at 8 o clock as had been suggested. will do the rear today with the stem at 6 o clock as the instructions say.

BUT so far i'd say its worth the little bit of money i spent. interesting note: this is the first vendor ive dealt with that charged me LESS than what i agreed to pay. when i got the bill they had reduced shipping and handling by 4 bucks. refreshing
