Long Teng 301D. I have a 268 and love it. the 301 is more recent, lighter, and takes wider tyres. It's a chonky looking boy. And because their marketing budget is a grand total of zero, it's cheap. They OEM for Argon 18. I've built 2, very well finished. And i've ridden mine over 8k km this year, so i'm confident saying they make good stuff.
