Surely right, but after my front puncture on the road, and my rear change of the tire, have (and after reflection
) put both heavy tubes; my program is more off road, and never highways ... So for instance no noticeable change ... 21" front wheel have ask me a little bit education after so much 19" , yes there is a little more gyroscopic effect ; but no noticeable change on the kilometers done, only much more confiance on stony tracks with reinforced inners.
