BUCKLOS MTB Mountain Bike Single Speed Square Taper Crankset -170mm Cranksets Bicycle Crank Set with 104BCD 32/34/36/38/40/42T Round/Oval Chainring Fit for Ebike/Commuter Bike

Una biela no trae el enroscado para el pedal, tendré que devolverlas, pésimo!

Fit perfectly on my bike..easy to add the chainring. It even came with the bolts to attach a chainring.

Mounted up with a narrow 113mm bottom bracket and still had to mount the chainring to the inside of the crank arm just to get a 52mm chainline(3mm outside of ideal, but still in the acceptable range). The chainring mounting holes are not centered in the crank arm. This just looks bad, especially since I had to mount the chainring to the inside, making the badly positioned holes totally visible. The chainring has an almost hooked shape to the narrow teeth and the chain jumps very badly in the largest 5 gears and the smallest gear, meaning I only have 3 usable gears that the chain won't come off. It doesn't matter which direction I run the chainring, either. I am very disappointed overall. I am going to try a different chainring to see if it works any better. I thought a "Narrow-Wide" chainring was supposed to retain the chain better, not throw it off worse!

This crank arm set works fine. I installed them on my wife's bike a couple months ago and it just sat, but after one ride the anodizing is peeling off and she cut her finger on one of the flakes

Purchased to upgrade wife's Aventon Pace 500 e-bike since this was the only multi-color ring gear with a square taper I could find with the correct sizing we needed. Removal of old ring gear went fine and cleaned up the square taper before attempting to install this crankset. When trying to install, the taper on the right side of the bike was fine and mounted near flush to the bearing face (nice fit). However, on the left side of the bike (drive side), the taper on the crank was too small and was not correctly machined to where there was about a inch and a half gap between the bearing face and the back of the crank. Tried filing down the small spots but then realized that the back of the crank was even missing the recessed area beneath the beginning of the square taper so it wouldn't have fit flush even if I completely widened the square taper areas. To avoid a janky and loose crank, I just shelved this one and will need to explore other options. Just found it odd that the right side fit fine and the left did not. I realize that there are different types of square tapers (ISO, JIS, etc), however this and the Aventon are both JIS so not sure why this was so terrible. 2 stars for the product looking very nice on delivery, but negative 3 stars for fitment.
