Please don't make fun of me. I am a newb, only 17 yo, and there is nobody around me to give me a advice.
So here it goes.
I bought jersey and shorts. And I was wondering if I am supposed to wear brief under my shorts.
I was also looking if there is any underwear made specially made for cyclist, and I encountered baselayers. I researched a little bit... and I am guessing those are for cold weathers. So yeah... what do I wear under my shorts?

Question #2. So far, I bought these:
Windsor Knight 2007 Bike $800
1 Jersey by DeFeet for $17
1 shorts from Performance $20
1 gloves from Performance $15
1 Blackburn frame pump $20
1 tool kit $20
1 wedge bag $10

About to buy
Ascent R-18 road helmet $30
Cannondale RS 1000 Road shoes $50 (I believe these are SPD compatitble)
2 Glueless patch kit $5

Also I have VP-61 SPD pedals and cleats that came with the bike

So yeah... I am on a tight budget. Do you think I am missing anything? I wanna go on a long drive without looking like a newb.
