Mountain bike Accersorizing?

So I am in need of some shoes and a helmet desperately and I am also looking into getting disk brakes for my Trek 6500 about how much should I spend on Shoes and a helmet i mean are more expensive shoes really that much better.???

If they are your initial pair of shoes,... honestly... don't spend too much... maybe $100 at the MOST. You can find some pretty good deals sometimes. Expensive shoes vary... some are lighter in weight but not strong while others are the other way around. Try 661's or even some PricePoint shoes.... they are good and decently priced and decent quality too. On a helmet... spend some money on it... at least $40-100. With helmets... price makes a difference on how many slots for ventilation you have as well as the material. the really cheap helmets are... well... cheap. Bell and Giro are good companies with various price ranges. As for the disc brakes for the 6500... if you plan on keeping the bike for a while... go with hydraulic brakes... Hayes and Avid are a good way to start... Magura and Hope are a little more advanced. If you think you might buy another bike in the future... get mechanical disc brakes or leave the bike as is. You could also look at replacing the fork if you want to keep the frame for a long time. If not... again... leave as is.

Though it's tempting to get a good deal on shoes and a helmet, you should invest a little time in the try-on phase with these two purchases. If you want to use your bike to get you to fun places where you might also have to do some walking and don't care to drag a second pair of shoes with you then consider something you can spend some time in. Try on helmets from all the helmet makers where you shop for your bike stuff. All helmets do not fit the same, but you may find that an inexpensive one fits as good as you want it to. In any case you can always try-on then buy on line if your not ethically torn. You just want to have tried the stuff on first so that you can order the correct item by model number. Good luck. Just as a side note: Make sure your hubs are disc compatible on your 6500. Otherwise it's a wheel set as well

As long as the shoes fit you well cheaper ones are fine. Look for sales always. You can get reasonable shoes on sale for around $50 and the same for a helmet. Same goes for the helmet. Some fit you better than others.
