It's an entry level cheapy, you can tell by the welds - if you can call them that, the plastic hubbed mag wheels and the reflectors. See here: http://bmxmuseum.com/bikes/blazer/

Post a picture, or maybe ask or search for your model on bmxmuseum.com

Odyssey trail mix magnesium sealed bearings.

Another here. Been at it again since around 2008 although I hadn't ridden much in the last 2 years but back on it now. I ride trails mostly. Gloucestershire

If there's play in the head tube then its the headset. If the 6 stem bolts are tight then its not the stem.

All anodised rims will show brake wear eventually. Hard anno is better but still it wears. G sport or odyssey chrome is really good. Older Sun Big city rims also have good chrome. Avoid primo, their chrome sucks

Odyssey sealed magnesium trailmix pedals are great! I've been using them for 3 years now without a single issue ever. No play at all and the bearings still feel brand new.

Thanks. Yeah its the chest mount

Especially for some who is in GBR! MDS all the way. If you're going to be bashing into shit.
