Hi,
Ive found two different frames on eBay, one being a base ta26 for 150 pound and a non branded frame for 39.99 and i cannot see the difference, they are both alloy frames the base ta26 is a 13" frames and the other is 12"....
here's the link to the eBay shop
I'm tempted to get the non branded frame but I'm cautious as to whether its good enough
