45 and 1st hybrid bike.

Bought a 2nd hand trek 7.2 fx with shimano claris crankset and gear upgrade.
Absolutely love the speed of the the thing.
Was overtaking buses earlier.
I've always ridden mtbs on the road and can't believe I've been missing out on the speed of a good hybrid.
Not sure of the year of the thing but he had replaced cranset and brakes and chain.
Still has brake blocks rather than discs but they work fine.
Tyres are Hutchison nitro and says inflate to 100psi which again coming from mtbs is crazy.
I can only manage about 80 psi with the small handheld pump I have.
What pumps are good for easy 100psi.
Cheers
