General Information
Grimeca are a well known wheel manufacturer of motorbike and moped wheels. Unsurprisingly, this wheelset looks like one that you would expect on a scrambler or a street racer.

The Bassano name was used on three wheelsets, this one the 3 Razze Avio ("Aviation Racing") and the 6 Razze Avio, which have 3 and 6 spokes, rather than 5. The "(S)" refers to the shape of the spokes, which are s-shaped in cross section. Both these wheelsets came as both rim braking (shown) and disc braking. They came in a huge range of colours (from brushed bare aluminium, through yellow, red, black, blue to lurid greens and worryingly atomic orange). The paint work looks like the wheel was dipped painted but it could be factory sprayed or powder coated.

Being one-piece wheels, bearing servicing is hard and truing is almost impossible (without a frame and a hammer). These are seriously heavy wheels.

There are a small number of design flaws in the manufacture of these wheels: their weight being a significant one. However, the worst design issue is that the rims use a single chamber deep well, which is partially filled with a rubber d-section, solid rim-tape with a special valve-hole fitting. These regularly fail, ripping the inner tube apart. This is fairly easy to overcome by using insulation tape to prevent the edges of the rubber tearing the inner tube.

Brand Information(click to expand)
Grimeca are an Italian motorbike component manufacturer. They are well known amongst motor bike enthusiasts for their well made and widely available wheels.

Grimeca's expertise in making motorbike wheels spilled into making the outrageous Bassano "3 Razze Avio", "5 Razze Avio (S)" and "6 Razze Avio" wheelsets from caste and milled aluminium, which were the company's only known foray into the cycling world; although, it is thought that some branded brake callipers are designed and made by Grimeca for other brands, however. The three spoke 3 Razze Avio from 1990 are very rare. They are designed for down-hill racing. Razze Avio means Aviation Racing in Italian. The 6 spoked wheels are the lightest but are still fairly substantial.
