Thank You Yoseph, Its a BLAST on the trail with Eagle!!,..still,...still,..yea,..still waiting on the Sunrace 11-51>12spd. It has some VERY interesting cog tooth count numbahs . I have their 11-50 and like it's build quality. This is an XG1295 10-52. Haven't had it out on the trail yet.(in this configuration) *Just installed the 520% bits yesterday. But DAMN does it shift like buttah under load with the black ti nitride coated chain and cluster! I have to admit I do like the Eagle 12spd stuff. I have a GX and an NX Eagle derail on BO.
