Would like to hear from Tandem Pro owners their opinions on the trike. We are thinking of a possible purchase. I have heard some negatives about idler issues at front boom where the idler guides power side chain under cruciform. Anyone have an issue with this idler? Also do you have IPS and have you had any issues with it? I have heard a couple of reports about issues with the IPS on the Tandem Pro. If you were buying a tandem trike today knowing what you now know about your tandem pro since owning it for a while, would you buy it again or something else?
