Innovation in style, engineering and security. The new SIP tubeless rim, successful and reliable. This rim allows you to use tires without a tube. In case of a puncture a sudden air leak will be prevented, the air pressure will decrease slowly. Blown tires will be a thing of the past. So will valve tear offs or punctures due to tubes beeing trapped between the rims during assembly.
The SIP tubeless rim combines the advantages of a classic cast rim with a high production accuracy and quality. The design is a tubeless double hump rim. This hump prevents the tire from slipping into the rim well in case of a puncture. The rim rotation is very precise. The rim is aluminium cast and CNC machined. The surface finish is perfect. The valve is included and already mounted. The rim is currently available in polished aluminium, black, black with polished edge and silver.
2.25-10'': At last the sporting giants among the Vespa models produced during the sixties can enjoy the benefits provided by the SIP tubeless alloy wheels! Due to the fact that members of the SIP team also own road-going Vespa models of this type, it was only a matter of time... All currently produced 3.00x10'' and 3.50x10'' tyres are fully compatible with these rims. Wheels of this size are the typical sparepart for the famous Vespa GS 160 and SS 180 models. If your scooter is fitted with a PX motor you will require the 2.10-10'' (PX) sized version of our tubeless wheel to complete the conversion successfully. Our SIP tubeless alloy wheels are top quality state of the art products and also possess a security feature in the form of a special recess along the inner diameter to allow the fitting of an ABUS wheel locking system when the scooter is parked. We do not intend to produce a huge number of wheels in this size, so they will not receive individual homologation. If type approval regulations prevail in your part of the world the documentation available for the almost identical 2.50-10'' wheels is usually accepted by your local vehicle inspector for approval.
Conclusion: innovative rim, high-quality workmanship, additional security. This product has successfully passed our long distance and fatigue test!

SIP-TIP: keep some tire sealant in your globe box.
Attention: Please contact a qualified workshop for accurate and damage-free tyre fitting (tire tool and appropriate fitting basis highly recommended). By all means make sure to avoid any damage to the surface! A lot of tube-type (TT) tyres can also be used as tube-less (TL) tyres. When mounting the tyre, make sure to use mounting paste. If you use oil or other inappropriate lubricants, the tire won’t sit firmly on the rim. Danger! Make sure to always check clearance of engine and accessory parts!
Mike Betz, GSF, 05/2010: "fantastic, problem free installation with the normal tire mounting tool, the high quality workmanship of the rim and the exact fit. Weight is also great, normal tire sets are much heavier. A win win situation from the security aspect due to going tubeless. I don't expect to have any flats this year, cause all three sets of tires have been converted to tubeless ;-)"
