I’ve ridden my MTB almost every day. The crank arms are 175 mm. The sprocket is 36T, 104mm BCD single speed ring designed for 10 speed drivetrains. The box included a BSA 68/73mm bottom bracket.Initially, I installed the crankset w/the original Shimano 8-speed 11-32T cassette. I rode it like this issue free for a week before I swapped out the chainring for a Fifty-Fifty 104BCD 36T NW Oval chainring. This, I rode issue free for a week as well. I then upgraded to a SunRace MS3 10-speed 11-42T cassette, Shimano Ultegra CN-6701 10-speed Chain, Shimano Deore XT RD-M786 SGS Shadow Plus rear derailleur & have now ridden it almost daily, issue free.The installation was simple. I upgraded from a Shimano square tapered bottom bracket to this Hollowtech II. Removing the old bottom bracket & cleaning in prep for the new bottom bracket was the hardest part of the installation. The improvement was amazing. I knew it would be better, but was surprised how much better.The set did include spacers, but I ordered a couple extra spacers (Shimano FC-M760 Hollowtech II Bottom Bracket Spacers, $6). These can ware & break. I think it’s a good idea to keep a couple extras on hand so if one does break, I won’t miss a ride waiting for the part.For me, this was a solid upgrade, a great crankset, Shimano quality cranks & bottom bracket at a great price (sub $120). If you’re looking for a new economical great performing crankset, the Shimano FC-M640 Zee 10 Speed Crankset may be a great choice.Thank you for taking the time to read my review, I hope you found it helpful. ### ⭐⭐⭐⭐⭐ Great Cranks! *by L***R on Reviewed in the United States on April 19, 2018* I use these cranks for bike polo and singlespeed MTB, they rock! Nice wide q-factor, but make sure you know your bottom bracket shell width before you buy these!!! They come in two spindle lengths so if you’re getting these for a 73mm BB shell you want to get the 83mm spindle. Same price as the standard. Comes with bearing cups and spacers. ### ⭐⭐⭐⭐⭐ Great crankset for under $120 *by F***R on Reviewed in the United States on August 2, 2019* These fit on a Big Ripper. I was worries at first because I had to use all 3 of the included spacers but it fits great and there are no unusual noises coming from the cranks. They are light, stiff, easy to install, and look great, I purchased them again and put on a different bike and about to grab another set for another bike. I personally love them. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/388712539-shimano-fc-m640-zee-10-speed-crankset](https://www.desertcart.jp/products/388712539-shimano-fc-m640-zee-10-speed-crankset) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-13*
