The new Guzzi (see sig) has Alpina STS spoke/laced wheels. They take tubeless tires. The key is the STS system uses a nitrile or silicone o-ring up in the spoke root within the rim to seal it from air pressure bleed. There is no sealing strip or anything running the inner perimeter of rim on top the roots. As far as I can determine, it is a very reliable setup and Alpina Raggi of Italy has been making them like this for a long time without any major problems. Stelvio owner manual says to check/inspect spoke tension at each service interval which is 1st svc at about 1000 miles then every 6200 thereafter. I've not had a spoke/laced bike except for the 1998 Harley Sportster XL 1200 95th Anniv Ed I learned on in 1999-- had a cast rear wheel but laced front. Always let the HD dealer service it, so never got to experience spoke maintenance. After that it was cast road wheels on my Ducati's. Watched a couple Youtube vids of mechanics showing how to check spoke tension with the wheel on the bike. I'll be using a Tusk spoke torque wrench which is specifically made to check/set torque on spoke hex fittings. Have the STS maintenance manual which states correct torque for each spoke fitting is 4 - 7 NM. What I'm looking to gather here is agreement on methodology. One vid the guy said to start at the valve stem and do every 4th spoke, then when you're back at the stem, do every 3rd, then every 2nd, and so on and that prevents any chance of moving it out of true. Just to clarify,not a question about how to TRUE a laced wheel. Way above my skill set right now. Just about routine checks for spokes that've loosened to below 4nm. Thanks in advance to the crew here, you're always helpful with knowledge beyond my own.
