On-One Pompino is a frame that hardly needs introduction. Most people build them as fixed or SS. We built it around a 3-speed hub, or actually we built it around two separate 3-speed hubs. The first one was a Shimano. It was on the bike for a few months but the first gear on the hub was very inefficient and the kick brake was a bit annoying to a rider who was used to hand brakes so it was exchanged for a SRAM T3 freewheel version.
The bike was eventually ridden for well over 10000kms. The component on the Pompino worth mentioning were
- Dimension Disc Cyclocross fork
- Hayes MX-2 XC front disc brake
- SON Disc front hub
- Brooks Flyer saddle
- Busch & Muller Seculite Cross Bracket
The drop-outs were originally of the mountain bike width, 135mm. The 120mm drop-out Pompino would have been a better option but they were not available at the time so the drop-outs were cold set to roughly 120mm for the internal gear hubs. The OLN width for the SRAM T3 is 117mm.
The bike was actually crashed after a couple of months on the road and it got quite a violent hit from a van. The rear wheel was smashed but the steel frame only suffered couple of hardly visible nicks.
Overall the bike was a fast and reliable ride. After some 9000kms the SRAM rear hub started to make squeaking noises and it was overhauled. It had gathered some rust from the water leaking from the non-freewheel side. The bottom bracket was exchanged at around 8000kms. The bike consumed a total of two pairs of brake pads over its lifetime.
Some remarks on the bike. The clearings on the forks were quite narrow. So much so that putting on a studded winter tire at the back was always a bit of an exercise. The widest winter tire it would accept was 32mm with fenders. But to accomplish that the rear wheel had to be placed at the rear end of the drop-outs with the chain length adjusted accordingly. The original front fork was too narrow for such a tire but the Dimension Cyclocross fork managed the winter tire quite easily. Having a disc front brake was very useful riding around city giving a sense of security whatever the weather. One small detail was the use of Busch & Muller Seculite Cross Bracket that mounts one of the rear brake bosses and the rear light is fixed to the bracket. The bracket doesn’t prevent using the rear brakes and the light is visible and secured reliably.
