Hey my sister recently bought a road bike and after a couple of cycle rides she wanted to pump up the tires. we bought a Bontrager air support plus pump, but for some reason the pump really struggles/hard to pump and won't reach the 95 psi level which recommend for the tires. Is this a fault with pump or something else like the inner tube?

Any advice or help will be great

Thanks

Sam
