Awful these bikes are shit

These bikes are trash, Chinese junk, if you are looking for something BF that’s going to last and not just a cheap bike look elsewhere. Bought a state fixed gear and out of the box the fork was bent, and you had to tighten down the seatpost clamp to the point the clamp bent out of shape to even get the seat to kinda stay in the same place. Had them then another fork out and it was the Wrong color!!! Then I ordered what size seatpost clamp it said to buy on the website “cause after I tightened for the second time the clamp bolt broke” and it said 29.8 so I ordered a Thomson one, turns out they were wrong it’s not that size.... done with this trash. Never buy from them

29.8 seat post clamp

These are good, just do not overtighten the bolt because the clamps are good, but the bolts strip fairly easily.

Good item works as said

First one failed.....

I had to purchase another Seat clamp due to Failure of the first one that came on the frame.
State did not have black in stock. So I had to go with silver. Not my first choice. But at least it matches the badge on the head tube.
Glass half full, right?

Black clamp

This clamp works well and is made really good, nice color, and clamps what it’s supposed to

Exactly as described

I ordered one and it got lost in transit.
Emailed the company and they got right back to me saying they had already mailed another. Will definitely order from the company again.

Love it... but...

I love the bikes, it’s great. But it did have some quality control issues. There’s a dent on one of the seat stays (near the rear wheel) that’s has been there since I got it. It doesn’t seem to be a problem at the moment but I do sometimes worry if it could affect the structural strength
