Mavic TN719’s here, built on Surly Singlespeed hubs by my own clumsy hands. Given fair bit of abuse & no ill effects to report. Also tried a TN117 & despite my fears due to its £22 price tag, its running perfectly true still.
Have looked at Stans for a new wheelset but having held a TN719 rim before lacing, & being amazed at how little they weigh given the job they do, I’m struggling to see how Stans have lost the weight without losing some strength. Plus they don’t have eyelets, & I think this makes the quality of the build all the more crucial. My clumsy building skills are best suited to eyelted rims for now. 🙂
