SIRDAR 27.5" S-900 27-Speed Mountain Bike

Joshua Harrison : I will update this, after I bring this product to a bicycle repair shop. I got this, despite the mixed reviews, in hopes that my purchase would not be defective. The hardware seems wonky to me, although I am no professional. 1 of 4 handlebar mounting bolts was not flush/dethreaded, this causes the handle bar to twist forward when you lean forward because you cannot make the connection tight enough with 3/4 bolts correctly threaded(not damaged)… I’m disappointed in the product… The derailleur was nowhere close to correct…only 2 of the 3 front gears, and 4 of 9 back gears could even be used, upon complete assembly.

The company was easy to communicate with once we could speak by email. The amazon communication system is terrible as it does not allow creating threads with previous replies embedded, making conversation difficult.

***Updated Review***

Still one star. I figured out how to adjust the brake so that I could open the calipers. When i did this, the wheel was looser, but it was still sticking in the brake. I then realized that the brake was out of alignment. The picture shows that one of the washers is squished and that the caliper is not aligned with the rest of the wheel holder assembly. When the wheel is on (next picture) the disk rubs up against the caliper assembly. I'm unable to unscrew these bolts to realign the caliper because the bold appears to be bent. This appears to...
