BUCKLOS IXF 104 BCD 30-52T Mountain Bike Crankset -Hollow Integrated MTB 170mm Crank Set- Aluminum Alloy Bike Crankset with Narrow Wide Tooth Chainring Bottom Bracket Bolts (Black/Red)

Arrived sooner than expected. Only issue I had was minor, but major at the same time. I don’t have the sprocket installed yet because instead of receiving 4 bolts and 4 nuts I got 3 bolts and 5 nuts leaving me having to purchase hardware from a local bike shop later this week. The crank set and bottom bracket went on smoothly and everything fits great in my 2020 GT Agressor Pro.**** update**** I wrote the seller about the mix up with my hardware and within a couple of days the new hardware arrived in my mail box. EXCELLENT CUSTOMER SERVICE!!!! And I’ve put about 40 miles on these cranks so far and they’re performing flawlessly

These are a fantastic upgrade for older OEM cranks. Affordable and STRONG! I'm using these on my AM build and love them. Company is great to work with and will help to solve any issues very quickly. I have used Bucklos in 9 builds now and will always look to them first for my parts now.

Spend a little more and avoid this company. Product is better than their business and that is still paying a compliment... They are middle men and cheap with poor work ethic. If it benefits them they will respond to you, if it doesn’t they don’t worry about it...

Seems good quality, very sturdy. But after my third use, I began having nonstop issues. Constantly have to take the chain ring off and hammer it straight again because my chain keeps snagging on it. It’s caused the mounting holes to wallow out a bit and it’s not holding up too well anymore

the left side plastic bearing insert that actually centers the crank shaft on the bearing was incorrectly installed and caused it to be distorted. which makes it impossible to install the crank shaft. the insert is unusable... which makes the bottom bracket useless. very disappointed. i am a professional bike mechanic and have never seen this type of issue with a bottom bracket.
