rotorbug Posted May 30, 2014 Posted May 30, 2014 Does Stan's sealant contribute to rolling mass? Ie. if I reduce amount of Stans liquid in the tyre, will I reduce the rolling mass? nonky 1
Johan Bornman Posted May 30, 2014 Posted May 30, 2014 I have no doubt that you can answer that question for yourself. Underachiever, SamL1220, Skubarra and 3 others 6
Guest EdEdEd Posted May 30, 2014 Posted May 30, 2014 (edited) Well of course it doesn't... it floats in the middle of the tube and does not weigh anything! Welcome back Johan... You've been away awhile (pst, it me kalahari ou/latent blue) EDIT: hows scotland? You back in SA? Edited May 30, 2014 by EdEdEd
Guest EdEdEd Posted May 30, 2014 Posted May 30, 2014 honestly, does it matter?!?!?But what bout Strava!? Every second counts!!! nonky 1
rotorbug Posted May 30, 2014 Author Posted May 30, 2014 I have no doubt that you can answer that question for yourself. Its not a simple answer as not all the sealant rotates with the tyre. Most of it effectively sits at the bottom. The surface friction will work against the rotation of the tyre, but some will be carried around with each rotation.
rotorbug Posted May 30, 2014 Author Posted May 30, 2014 honestly, does it matter?!?!? Any increase in rotational mass will affect how quickly the tyre/rim will accelerate.
Guest EdEdEd Posted May 30, 2014 Posted May 30, 2014 Most of it effectively sits at the bottom. That depends on the speed of travel: centrifugal forces and what not...
Guest EdEdEd Posted May 30, 2014 Posted May 30, 2014 ......konsertina tyd......????waars silver?Speel johan bekfluitjie?
BarHugger Posted May 30, 2014 Posted May 30, 2014 Any increase in rotational mass will affect how quickly the tyre/rim will accelerate. ......so considering Newton's 3rd law, that will also affect the de-acceleration force (stopping power)........so maybe going faster one will need a longer distance to stop also.......so going slower you most probably will require a shorter stopping distance and be able to maintain your average speed over a longer distance.......which might contribute to actually going faster over a longer distance ie 70km.......?!?! blondeonabike 1
rotorbug Posted May 30, 2014 Author Posted May 30, 2014 I think I will just take some out as its quicker to get the answer I want that way! Was just wondering how little one can use to reduce the rotational mass.

Lone Rider Posted May 30, 2014 Posted May 30, 2014 From what I've experienced, tubeless tyres with 60ml sealant (minimum recommended per mtb tyre) offers less rolling resistance than tyres with tubes.
BarHugger Posted May 30, 2014 Posted May 30, 2014 ......one also needs to consider tire pressure and the surface type the riding will take place on to provide a definitive answer......is it tar, asphalt, compacted dirt track, loose sand, grass, mud, rocky inclines, twisty tracks, slippery downhill slopes or a combination of the above. Tire size is also a factor to consider.......
fanievb Posted May 30, 2014 Posted May 30, 2014 I have no doubt that you can answer that question for yourself. Welcome back sir! I hope the tech section will once again benefit from your vast technical knowledge
