To optimise the weight, strength and stiffness, the Reactor Carbon frame features a full UD woven carbon fibre frameset (Including chain and seat stays). It is available for 27.5” or 29” wheel sizes. These are two totally different, compromise free frames that were designed and developed at the same time. Each frame is simply tailored around each wheel size.
Speed or play: which do you value more? The maneuverability of 27.5” or the raw speed of a 29”?
All Reactor frames feature a “flip chip” to adjust the geometry from “Trail” to “Rail mode”.
- Trail – As the name suggests, this setting is best suited for trail riding. It is for riders who get as much enjoyment from the climb as the descents
- Rail - The Rail setting turns the Reactor into a corner shredder, dropping the bottom bracket 6mm and slackening the head angle by half a degree. It is there to maximise the descending capabilities.
To ensure the bike could climb as well as it descends, we designed the 4 bar horst linkage to have higher levels of anti-squat for climbing gears but lower levels when you drop down the cassette. This means that the bike can behave itself on the climbs but when you get it up to speed, it turns into a trail hooligan. The combination of low anti-squat and progressive rate give ultimate small bump compliance (removes rough trail and root chatter) with good mid stroke support for cornering/pumping and end stroke progression for aggressive riding. Balanced anti-rise figures allow the Reactor some squat when braking hard, maintaining rider position and providing a good amount of pressure through the tyre to ensure traction. The Reactor is designed to reward the rider and ensure you get that stoke factor in on any ride.

Ready to ride
Every bike from Start Fitness is fully checked & assembled before despatch and will arrive, almost, ready to ride. Each bike is assembled by one of our CyTech accredited mechanics and then packed into one of our custom boxes.
*This process has a lead time of 5-7 working days.
Unfortunately during peak times this may be slightly delayed. We will however, aim to despatch your bike as quickly as possible. Minimal assembly, with basic tools, is required before you can ride. Assembly tools are not usually included.
Making sure you are home
Once fully checked and boxed, we will contact you to arrange a suitable delivery date when you will be home to take delivery. Our bikes are despatched with a premium delivery service which usually delivers next working day (excludes weekends & bank holidays) for mainland UK orders, it may take slightly longer for some areas, Northern Ireland, Channel Islands and outlying Scottish areas. European bike deliveries usually take approximately one week.
Taking Delivery
Any mechanical or cosmetic issues need to be reported to us within one week of the delivery date. If you do not plan on using the bike straight away, we advise that you remove it from the box and check it over ASAP as we cannot be responsible for any reported issues (other than standard warranty issues) later than one week from the date that the bicycle was delivered.
First Service
After a few weeks of riding (we recommend around 6-8 weeks, regardless of how much the bike has been used), a new bike will need a service to make final adjustments and to re-check all nuts and bolts. This is necessary as the bike goes through a ‘bedding in’ phase, after which, final adjustment may be necessary. We recommend that this is carried out by a CyTech qualified mechanic.
It is important to have these checks carried out to prevent any avoidable problems which may not be covered by warranty and to ensure the smooth running of your bicycle. If you’re local to us, we’re able to offer this first service free of charge* at our Newcastle store (NE1 6JE). You’ll just need to call our workshop on 0191 917 3825 to book your service in, and don’t forget to bring your proof of purchase when you drop the bike off with us.
If you’ve had the bike delivered, it will be your responsibility to ensure a first service is carried out at a trusted bike shop local to you, preferably by a Cytech certified mechanic. Start Fitness are unfortunately not able to cover any costs associated with this service if carried out by another store.
*Please note that this complimentary check-over does not include any labour to replace worn parts or to fit new accessories. All bikes should be delivered to us in a clean and serviceable condition, or a £15 cleaning charge will be payable.
Bike Servicing
Bicycles need to be serviced regularly, as a guideline we would advise on at least one full service per year and/or a standard service twice a year. If the bike is used regularly in adverse conditions, more regular servicing may be required.
