Zeron 2X 36/22 Boost

This is my 3rd Zeron cransket, although the other two came with the zeron chainring direct mount for single chainring, but I prefer this 104 BCD spider for using other brand rings if needed. Great durability. Easy to install. Works with the Shimano branded BB as well (I've tried it) but the included BB works well and last a long time. I can't think of a negative. They are a bit heavy but the price is right and they are rugged in my experience. I've had the Zerons since they first came out - nothing but good experiences running these.
