Funny you mention Marks name as I've been working with him all afternoon on replacement stuff for this issue. Seems like a super guy. You can bet I'm making darn sure most of the componentry I purchase from him will be able to go on something other than a Santana if our fixes don't stick though! You know, everyone likes to be proud of their bikes but now that I have a few tandems my pride is gravitating toward the other than 160mm options. I'm just plain getting tired of work arounds, band aid fixes and proprietary parts for the sake of lining a certain guys pocket. It's been a hard lesson that at least my kids won't make.
