Hello on new to the forum and new to riding last time i rode a bike when I was 10 I just bought a raleigh talus 3.0 I'm 6,1 300 ibs seems like a good bike to me can some one give me some advice or opinion on my bike and size also what is a good cheap website to buy parts for my bike I want to get new rims and seat. Also where I can find some good trails. I have a bump on my tire already like a little ball do I need to buy a new tire now it seems to be fine just wobbles a little bit. Thank you in advance

You will need to get a new tire to fix that bump right away. It will soon pop and leave you stranded.

I have had good luck and pricing with Blue Sky, Jenson, Nashbar and Performance are just as good.

See if you can find some other Mountain bike riders and ask them about trails. Another way is to visit a local bike shop and ask them, they might also have flyers.

Raleigh is a solid name in bikes. If it feels comfortable to you, ride it for all its worth.

Thanks brother i don't know much about bikes just started today so now I'm learning that little ball I have i thought I wasn't nothing to be concern about how do you get those?

New to forum so hello. Just picked up this deal http://handlebargains.com/deals/acos and thinking about some DH armor? They carry Troy Lee? Is that good stuff? Thanks.
