I am running them on my single speed and I am going to run them on my geared bike. I would hesitate to run them if I had to ride through alot of rock gardens on a regular basis. I'm using 14/15 spokes. I have sturdier rims on my FS. I posed this question a few weeks ago and the response I recieved was probaly. If I had to rely only on one wheelset I would go with the Rhyno lites. Mike C is building a wheelset for me with these rims.
I have delgado rims on my 29er and they have held up good so far. I have only put around 100 miles on them, but those were 100 hard miles. I have taken them and done things that have sent my other rims out of true. I say go for it, good rim and a fair price
