Review on 🚲 BUCKLOS 【US Stock】 MTB 170mm Square Taper Crankset with 104 BCD Mountain Bike Narrow Wide Tooth Chainring 32/34/36/38/40/42T, Single Speed Round/Oval Chainring and Crank, compatible with Shimano, SRAM, FSA by Chris Kidd

Anyway it's really good. This is a fantastic and inexpensive way to try out an oval chainring and experiment a bit with your bike. However, there were some problems with the installation. The crank is too far out compared to my stock sprocket and shifts alignment so I had to mount the ring on the opposite side of the groove. It's not designed for that, but I don't think it would pose a problem for basic trail riding. The other issue was that I had to pair it with a chain tensioner to keep the chain from falling onto the rear pedal, but chances are. If you have a budget bike like me, you should still buy it. Cost me €10 extra. I have a safety chain guide but I don't think it's necessary ($20 more). It has its logistical flaws but is still a great ring and crank set if you install it properly. How does it actually work?: If you get all the nuances, the oval shape in the hills makes a noticeable difference. Otherwise the sensations are exactly the same, that's the whole point. No loss of speed on level ground, but significantly more efficient where it counts. Other Notes: A general rule of thumb I've learned is that an oval chainring effectively works as a ring 2 teeth over AND under (the oval shape changes the position of the sprocket). chain relative to the central pin). But it's also a physical adjustment. If the largest ring that will fit comfortably on your bike is a standard 36T round T ring, you will need to purchase a 34T ring to ensure it will still fit (which is what I got). Otherwise it may get too close to the chainstays and hit the bike.
