Hello everyone,

I used to ride a single gear cycle and could easily reach speeds of upto 45kmph (28mph) on plain roads. But I recently bought a new bike, Raleigh SE01, 29er, 21-speed, dual disc brakes. I can hardly reach 35kmph (21mph).
Please advise me on how to reach higher speeds and some proper gear usage advices.

Regards,
Jay Tee
