    Manage to break the original!

    Seems a little sensitive chain. I am not a big guy with brutal power, still managed to brake this chain on my gravel bike. Probably my fault - at least partially. Managed to "hack" it back together and get home without a chain tool - also my fault. Still I have not had this problem before with any other chain. I got a new one - quite expensive but reluctant to try something else with the SRAM Red 12 setup.

    Best group set on the market and one of the best pieces is the chain, solid, extremely quiet and durable...

    Happy with the SRAM chain. I find the flattop is a bit harder to keep lives and quiet but the AXS system is excellent.

    I am new to the 12 spd world but run wrap 11 and 12 speed on three separate bikes

    Love the range the 12 speed gives you. The chain is light and quiet. But pricey for sure and rarely on sale.

    These new chains look like they are lasting longer than my old 11 speed chains according to the chain checker tool. I have not had to put this chain on yet because the one that came on my bike still shows good. I went with the Red chain for the first chain change but will probably go with Force on the next one it is half the price.
