I never really felt fully comfortable on my bike. It is not that I am a bad cyclist, I am in fact quite good. That said, my palms tend to get sweaty. Following traffic rules means that I cannot cycle on the sidewalk, and with my sweaty loose grip I was always afraid of what might happen to me in busy intersections.
To ensure my safety I knew I needed two important bike accessories. For one thing I needed a sturdy helmet. If something was going to happen I wanted to be sure that my head was protected, but perhaps less obviously I need some handle bar tape. Cycling accessories are not all cosmetic and high tech. Some of these items are absolutely must haves, simply to effectively and safely bike around.
Some extra gripping tape is important to keep on you at all times. Even if you do not have the same sweaty palmed problem I have, things can get treacherous on the open road. You want to be able to keep as strong a hold on your handlebars as possible should turbulence occur.
So when shopping for bike supplies, do not forget the handlebar tape and ride as always with safety in mind.
