The three bits of equipment that will make your bike faster are
1) Track pump. If your tyres are at a good pressure you go faster.
2) Clipless pedals. As you can do power on the upstroke and downstroke, max power to the road is increased. Slightly faster on short uphills for instance. The main problem I have with these is that I now have 3 pairs of cycling shoes and it doesn't seem like enough
3) Fast tyres. Switching from a cheap tyre like an Ultragator Skin to a fast racing tyre like a Michelin Pro Race gives lower rolling resistance and superior cornering. Tyres like this make your bike seem like it costs £1000 more, so are good value for an extra £10 per tyre
