I'm really looking for a solution to my newfound fear of fast descending on our tandem.
After briefly seeing 60mph on the descent of Slumgullion pass, and getting over 50mph many other times during our weeks tour in the southern mountains, the front tire blew off the rim on our first casual ride when we returned home. It happened at about 30, after a hard, but fairly short application of the front brake. After sanding most of the dings out of the Fir rim, I put on another set of the same Conti GP3000's. Removed them after reading stories of other Conti blowoffs, and put on a set of Ruffy Tuffys.
Still being uncomfortable with the dinged up rim, I had a set of Velocity Deep V's built up on Phil hubs, but now the 27mm Ruffy Tuffys look like a stretch for the narrower rims. Does anyone know of a chart showing tire/rim width compatability? How about a tried and tested tire for a 300 lb. team on these rims?
I'd like to regain the confidence to be as relaxed descending with the tandem as I am on my single, but with my beautiful wife in the stoker seat, I need to trust the bike completely.
Thank you for any comments -
