Buying your bike from usBuying your bike from us

Please note that to buy a Trek or Gary Fisher cycle you must be able to visit the shop in person.
“Trek Bicycle Corporation does not authorize our retailers to sell new or used Trek product over the internet or by mail order. Delivery should only be made to you at an authorized Trek retail location. This is for your safety. We want to make sure that your bicycle is properly assembled, properly adjusted, and is the right size for you. We also want to make sure that you receive your owner’s manual and consumer literature. Your dealer will also explain how to properly use your bike and answer any questions or concerns you may have.”

We think this is a good policy, for it means that you will receive good advice about the bike that's right for you, and take home an expertly serviced bike. Every bike we sell is not only fully assembled but serviced to a very high standard. As an illustration, we even remove the tyres and inner tubes so the wheels are properly dished and trued.
We also offer excellent after sales service, to include a second free service 6-8 weeks after the purchase of the bike.
This standard of service and peace of mind is all included in the price of the bike, and is not something that can be matched by mail order or internet sales.

Description:
GP4000 tyre with new BlackChili compound
- BlackChili gives a lower rolling resistance and higher grip
- An ideal secret weapon for the seasons main objective
- Vectran anti-puncture technology, tougher than aramid
- All black, 23mm option only

The Continental Grand Prix series of racing clinchers is the top choice of serious race bike specialists all over the world, and has been for many years. The latest incarnation is the Grand Prix 4000S which has the same construction as the GP4000 but with a new BlackChili special compound. S stands for sport, special and "schwarz" - the German term for black.

The all black Grand Prix 4000S catches the eye with its big silver labels. It matches every high-end race bike perfectly and can do more than just look good.

With the new Black Chili Compound rolling resistance is reduced by 26%, grip is increased by 30% and mileage is increased by 5%.

The new compound:
How are these figures possible..? The carbon filler particles within the rubber compound are reduced to 1/10th of the size of standard carbon particles. This creates a closer knit with the particles having more points of contact with each other, thus forming a tighter bond, (increasing mileage performance) and also with the road (increasing grip). Also the way in which the particles interact with each other has a dramatic effect on reducing rolling resistance. Black Chili was used by several ProTour teams in 2007.

Vectran anti puncture protection:
The all new Vectran breaker belt, developed and patented by Continental, surpasses even the famous puncture resistance of the former leader in this category, the GP3000. The extremely strong Vectran fabrics are more flexible and lighter than all other puncture protection materials. Vectran offers more resistance to cuts than Aramid, is five times as strong as steel and features less weight than a nylon double breaker. It also maintains strength in the wet.
