To me how I look on a bicycle is equally important as the bicycle itself. If I have to look like a spandex-wearing superhero (basically Spiderman with a cheesy helmet!) while cycling then, well, sorry, I will stick with my jeans and t-shirt.
But there are some bits of cycling gear I do endorse...
#1. Leg straps for protecting your clothes from being snagged on gears and ripped. I personally favour the small velcro ones, the larger "leg shields" to me are just unnecessary weight.
#2. A helmet you actually LIKE and are comfortable wearing, not just physically but also fashion wise. Again I prefer to go with a helmet that looks "manly" and not ridiculous. The pink helmet below is obviously not on my wish list and an example of what I would NOT buy.
#3. And last but not least... cycling gloves!
The gloves I am currently using (and have been for years) are my Atlas Weightlifting Gloves. They're not even meant for cycling. I got them for using at the gym because the weights were hurting my hands.
However I can't find that exact brand in stores any more, but I have found other brands which basically the exact same gloves. One company is Copper Canyon Cycling (sadly I can't find an example online) and other company is Saranac (shown below).
What I like about these gloves are they are black, totally badass fashion wise, knitted for comfort and let your skin breathe, and the leather is faux leather so it isn't going to offend any vegans or the veggie-curious.
In somewhat related commentary I think cyclists wearing too much spandex take themselves a little too seriously... and I also think it is hilarious when I cycle PAST them and show them that wearing all that spandex doesn't make you faster.
EXERCISE MAKES YOU FASTER.
