Bike and frame supply has vastly improved since the pandemic, but pre-ordering is still essential for some models and sizes. Hope HB916 frames are made to order too, so we have updated our pandemic bike deposit policy to take the current situation into consideration.

Please note - we can only deliver complete bikes to UK Addresses.

The ETA's (estimated times of arrival) we quote are from the information provided by the manufacturers and distributors. These dates are not guaranteed, as the manufacturers are also at the mercy of component suppliers. We will tell you the same dates as the manufacturer tells us.

We only take deposits on bikes we have on order with suppliers and have confirmation that we are going to receive them. We want to make it clear that there might be issues outwith our control that will prevent us from supplying the bike you want. If that happens, we will do our best to provide an alternative.

Deposits are non-refundable, except for when an ETA date changes by a month or more. If it looks like the date might change, we will do our best to find you an alternative.

If a bike arrives earlier than expected, it will be offered to the person with the oldest outstanding deposit, then the second, and so on. We'll then offer the bike to anyone with a similar bike on order. We should point out that this is a rare occurrence!

Bikes and frames up to £3500 require a £500 deposit.
Bikes over £3500 require a £1000 deposit.

We ring-fence deposits in a separate bank account until the balance of the bike or frame is paid, then the bike or frame is delivered.

We've tried to be as honest and open about the situation as it stands and not make promises we know we are not in the position to fulfil! We have great relationships with our suppliers, and we will work with them and you to try to get you your bike as soon as possible.

If you've read this and have any questions or would like to place a deposit, please phone us on 01330 828562.

We offer free UK delivery on all bikes unless bought through a Ride To Work Scheme.

We don't currently deliver complete bikes outside the UK.

Custom-built bikes can be delivered in kit form (for you to assemble) - we can include shipping to your country in your quote.

Sale price bikes bought though Cycle To Work schemes will have a handling fee added.

This information is intended as a guide only.

Cycle To Work is a Government Initiative to encourage cycling to work. The idea is that by cycling to work, you get fitter and healthier, and at the same time reduce congestion and improve air quality.

In simplest terms, your employer pays for the bike, and you hire it from them through salary deductions. At the end of the hire period, the employer can sell you the bike. (Until the bike is paid for, you hire it from your employer, so don't get fired).

Your employer might administer the scheme themselves, or use a third party like one of the following:

GoGeta
Vivup
Green Commute Initiative
Cycle Solutions
My Benefits World
Cyclescheme

If your employer doesn't offer Cycle To Work as a benefit, you can send them this employer information from the Government that outlines how it all works.

The Sentinel is a bit of a do-everything bike in the Transition range, up for all-dayers in the hills or uplift days.

Out of the box, the bike is set up with a 150 mm shock and 160 mm fork, but the bike will still handle on a 150 or 140 mm fork. The shock can be swapped for a shorter one to run the back at 140 mm.

Transition have given the longer-lower-slacker approach a name - "Speed Balanced Geometry" - but effectively it means short stem, slack head angle, short offset (42-44 mm) fork and a longer top tube, pretty much what you would expect from any modern enduro-orientated bike. On that note, all models can take a water bottle, though you'll need to use a fidlock bottle on the size small frame.

Never ones to shy away from a cheesy name, the Transition's "GiddyUp" suspension has fantastic small bump sensitivity and enough progression to run a coil shock without blowing through the travel. The Enduro Max bearings and additional bearing shields are a huge plus point for UK riding!

The GX spec carbon bike has a top of the range ROCKSHOX Lyrik fork and a Super Deluxe air shock, as well as the excellent OneUp dropper post. Dropper size and bar rise vary depending on frame size.
