G Sport is and has always been slightly less well known just because they don't have a large advertising budget but that really shouldn't put you off. The truth of it is they make the best wheels you can buy.
I know I shouldn't show preference but G Sport has to be my favourite BMX Company. The thought and attention to detail that George French puts into his products is second to none and it shows. Take for example the Marmoset front hub its a design that was in production in 2003 and hasn't had to change since, others have just had to catch up.
G Sport only makes wheel related products so hubs, hub guards, rims, Nipples and pegs or plegs to be precise. You can however invest in some more products designed by George French as he now works for Odyssey on their design team.
