Tioga dipped their toe into the 2-piece crank market from 1992-1996. The only other company in this space was Bullseye who released their legendary Bullseye MTB cranks in 1987 as they diversified from their BMX roots.
Bullseye cranks were both heavy and expensive compared to more traditional square taper cranks, so Tioga spotted the opportunity to push a more lightweight and more affordable 2-piece mountain bike crank with their tubular TIG-welded 4130 CroMo Revolver cranks.
Unlike Bullseye cranks which combine the drive side arm and bottom bracket axle, the Revolvers combine the non-drive crank arm and bottom bracket axle. A lightweight modular 6061-T6 alloy spider is bolted to the inside of the drive side arm. The arm can then be slid over the splined axle and tightened. This modular system enables the user to swap and entire spider with chainrings attached using just two allen bolts.
The 6061-T6 alloy cups fit both 68mm and 73mm bottom bracket shells with the supplied spacers. Sealed cartridge bearings are installed. Chainrings are not included.
Keen to promote their new cranks, Tioga sponsored the most well known cross country and downhill racer at that time, John Tomac, but even this didn’t work. The problem was that they didn’t have the cache of Bullseye cranks and there were reliability issues.
In the UK, we didn’t take to them and didn’t see the point when a good square taper/alloy crank setup was lighter, cheaper and offered more flexibility.
Despite the Tomac connection, there is little demand for these cranks from the retro crowd i.e. the lack of desirability from the 1990’s is still relevant today.
