They are great for those bikes that you want to be absolutely perfect, attention to detail is everything for me so I had to get these. They are very light, the finish is good but dosnt appear to be the most durable. They are very strong as well, also cone with a tool so no complaints (besides the durability of the finish).
Wanted to add some flash to my single speed that would match my Sugino crankset. Great finish and fit snugly. I hope that the finish lasts long and can withstand road grit. Only downside is the price being a bit steep for chainring bolts.
