Highway RPMS ?

I was playing around with the summit gear ratio calculator and foundÂ…
2.76 gear
29 in tall tire
70 mph
=2238rpm
Will the slant hold up all that way at those rpms?)

What??? What??? Blasphemy! ;) of COURSE it'll hold up.:) my '68 took me over 3000 in 9 days last summer. I've done numerous 1000 mile weekends with absolutely no problems whatsoever.:) and that's with 2.76 and a 26 inch tire on 14" wheels.
