  • Because this Cranksets is square hole shaped, you will need a square tapered bottom bracket to go with it.Note that this crank is a 170mm size and the length of the crank is chosen according to personal habits.

  • The chain ring mounting area has two sides. Placing them on either side will move the chain ring about 10mm. Do not use washers between the crank and the ring because there are no chain ring bolts that are long enough.

  • One the crank arm attaches to the chainring and then to the bottom bracket square taper bolt the other crank arm attaches to the bottom bracket square taper bolt on the other side one arm points up the othe points down direct opposite see less.

  • It depends on your application. A new bottom bracket will come with crank bolts. Or if replacing a existing crankset, you would just resuse the old crank bolts.

  • The package of this product includes a left crank arm, right crank arm and a chainring with 4PC chainring bolt. Does not include bottom bracket or caps.

If you don’t know how to work on a bike don’t try this on your own. You need a puller to pull the old one off, and they can be really difficult to get the new one on. But they work great for a great price if you have an idea of what you are doing.

After a couple dozen of pedal or crank to rock hits, they are still solid.

This is a great crankset at an incredible price. I am a heavier rider and it seems to be holding up very well with little to no noticeable flexing. Typically, I only get spline and hollow bottom brackets with matching cranksets because it is stiffer and stronger. I have had many square tapered cranks fail or round out on me. I am limited on selections because I am upgrading a budget fat tire frame, so getting quality upgrade parts is difficult. The finish and overall design look and feels like quality parts at an affordable price. This is a win win for my budget build.

I bought a cheap mountain bike that had a single speed chain wheel on the front. The problem was that the front chain wheel had too many teeth. Their consequence was that the gearing was way too high. I could only use the three lowest gears most of the time. I switched the 40 tooth chain wheel for the Bucklos 30T chainwheel. It solved the problem nicely. The cranks fit the old axle perfectly. The whole setup is about a pound lighter, including the crank arms and the chainwheel. It looks pretty sharp. It's interesting that the teeth on the Bucklos crankset are different sizes. Not sure what this is for, but the chain has no tendency to fall off the sprocket.

Took my touring bike from 3x8 to 1x10. Very affordable, high-quality product. Sharp look also.

Shipping was fast, packaging was good. This crankset fit perfectly on the bike and the chain line with the 30t chainring with a Shimano 8 speed was perfect. The narrow wide chainring is a little noisy in first gear with a 11-36 cassette but quiet with an 11-32. Time will tell how it wears but it functioned flawlessly on two pretty ruff trail rides so far.

I went to a long bike ride today and it was great it was worth it it is a little snug for a 12 speed I have a sram gx gearing set up and the bucklos 1 by did really good with it it’s just a little tight but nothing major

The front derailleur and shifter were not working correctly on my daughter's 24" bike so she always left it in one gear. Might as well make the bike a 1x with the 30t. Eliminated the non functioning front gears, made her life simpler, and lost a ton of weight over stock. Like 804 grams ton of weight! The gearing is also in between her stock 24/34 so it is better overall too. I use the same crank but a 36t on my mountain bike I convert to 1x10. So far so good.
