If its one of the trek shops that seem to be taking over all the shops on the island, I'd pass on the deal if they're too cheap to replace their own proprietary parts. Bugs me to no end that companies come up with this BS and expect the customer to just fork over the cash. If its a independent retailer that's selling trek I'd have to consider spending the cash. I like most of the shops here and really dislike that trek is taking over so many of the small places. Stopped up to a shop in East Northport and its now a trek shop, and I used to really like shopping Sunrise but they were bought out too.
