nice frame sliders Dr. mo

[M-Six Hundred]

i heard those frame sliders can actually snag the cement when its down and sliding and make your bike start fliping.

thats true... ive seen it first hand.. but also... delrin is most widely used since it wears as it slides... something harder than concrete wont slide as smooth along because it is harder than concrete.... anything harder than the thing it is moving along without much resistance will cause it to snag.. learned that in school.. if it is aluminium it will be hard to say but i can still happen.. ive never had it happen with anything soft.. but My motard bikes have tumbled if i dont run my axle sliders and it snags...

careful with sliders on the 600rrs, i dragged my plastic ones at west track,their set really low on those bikes

on the right track... its actually about the coefficient of friction between the slider and the track surface. This is what allows the slider to "Slide". If the coefficient is close to zero (what you want) it will slide forever without catching. A coefficient close to zero means theres little to no friction. Like sliding on ice. If the coefficient of the slider is higher then that of the tires sliding (or the second point of contact) then it will catch and flip. But the same also goes for if the tires are sliding along with the sliders. If the coefficient of friction between the side of the tire and the ground becomes too high then the tire will catch and flip the bike. Besides the coefficient of friction you also have the angle of the sider vs. the ground to factor in as well as the distance between the two objects on the bike sliding (usually the edge of the tires and the sliders). Those are the dependent variables but you can never predict a small change in elevation in the track, crack in the surface a change in the track makeup (firebird main sticky VHT for drag racing), the height at which the slider is from the ground before it looses traction, the speed it hits, ect. Honestly there are far to many variables to determine if i slider will work or not. Its more of a luck thing and people put them on to better the chances of saving their bike.

PS- The coefficient of friction between the ground and alluminum is usually lower then that of delrin. The main cause of sliders flipping the bikes is that they are too long. Take a look at most race bikes with sliders. They usually have them cut down or they come shorter (like Woodcraft). Its the main reason i cut mine down.

damn.. jerry's good...

[Blue Devil]

lol thats a cliff notes version. Taking all those engineering classes are paying off. This is most like Statics and Dynamics... Its fun shit and I like doing it.

haha showing off a little jerry ;)
