Question: Will these fit on a Genesis V2900?
Document: Had to find a different caliper mount adapter made specifically for a 160mm rotor to get it to fit properly.
The low end mechanical disc brakes that came on my new MTB bike were just awful. Once it became clear to me that no magic adjustment was going to improve the bad situation any further, I went looking for some replacement brakes. Some internet research lead me to the Avid BB7 brakes and this 160mm MTB BB7 brake package on Amazon.They were a bolt on replacement that fit perfectly and were simple to install and adjust.There were no instructions with them, but the internet told me more than I will ever need to know about them.Every problem I had with the original brakes are now gone with these new BB7 brakes and G2 rotors.
trail ridden about 20 miles and everything feels and looks great
purchased theese instead of the bb5's due to the fact both sides of the caliper have &#34;hand&#34; pad adjustments. If you dont already have brake mount screws for the rear you will need to get. this kit only comes with screws to connect to the mount not the frame (fronts bolt directly to your fork). Lines are not included just a heads up. will make loud noise your first few hard brakes but will quickly subside (assuming pad, rotor or both need a break in period of a few hard stops).
order said would take 3 weeks, showed up in 3 days, larger pad surface than oe brakes, work well on my 29er
great product only downside was no instructions but I figured it out pretty easily would definitely recommend this to others.
as one reviewer had made. the brakes came from china with lots of tape and a Custom inspection sticker. it had no instruction, but the info could/was download  via internet. also it came with a thank you gift but the description  was in Chinese. 4 stars cuz of the braking power with no instruction.
You need to find the online videos and be experienced at bike repair to install these correctly. They came with no instructions and a mixed bag of bolts and parts that are not easy to figure out at first glance. You will also need to pay close attention to the internet instructions for adjusting and setting up the pad distances.Once installed and adjusted correctly they work great. I replaced the caliper brakes on my frame near the bottom bracket that kept getting dirty and corroded requiring constant maintenance.
Very good were delivered very fast and everything complete.
They don't come in a box or with instructions, but they still are nicely packed in bubbly wrap and bags. The set was made in January of 2014 so these aren't some kits that have sat on the shelf for 5 years or anything. My kit was missing one of the small rubber dust boots that go over the brake cable, but I don't really care because of the great deal I got. I might in the future buy a rebuild kit for these brakes or something that has the dust boot I'm missing. Now as for the riding performance review, all I can say is that these really did live up to the hype I read online about them.
Answer: no
