According to the earlier poll, there are at least 20 PT SL2.4 owners on the forum. I'd be interested in any details these members can provide as to problems with the hub or computer. Please be as specific as possible as to the nature of the problem, the diagnosis and fix (if it's fixed) and your thoughts on the reliability of the unit. I ask because I'm about to put in a group order on PTs for my racing team and a bunch of the guys are considering the SL2.4. If I say it looks solid and they end up with problems, I'll probably have to relocate to, say, Australia.
