Excel dirt bike rim laced to bicycle hub
The 21x1.6 Excel dirt bike rim is the same size as a 26" bicycle rim.
The 19x1.4 dirt bike rim is the same size as a 24" bicycle rim.
Both are built to take a pounding, high flying and hard landings.
When you lace them with 10 gauge stainless spokes to a high quality hub like a Chris King... You can use dirt bike or moped tires....
Dirt bike tires are heavy...but indistructable
Moped tires are lighter but are limited to arould 35 mph.
I had Wheelmaster build me one for an experiment
A 21x1.6 laced to a ...It has held up... I think he used 9 guage spokes, I think 10 guage should have been used... THe holes in the rim were too large for the nipples he had...so he went with the spokes that had a larger diameter nipple....Its still on my yeti dh-9... but do the tire width, is incompatable with the GEBE Tanaka 40cc....
Wish I had a Morini
Be sure that your forks can take the wider tire... My 21. 1.6 has a 3" tire... it rubs slightly on the inner rear fork.. I should have used a 2.5 tire.
