We've been safely sending orders around the world since 2010. There's a handy shipping calculator on the shopping cart page so you can see the cost of postage as soon as you've added it to your basket. Your order will be carefully packed and sent with tracking & insurance, we despatch most orders within 2-3 days but larger items and orders placed before the weekend can take an extra day or two to process.

We accept returns, please notify us within 14 days and ensure the item arrives back with us no later than 30 days after the order was received.

We don't charge VAT, however, if buying from outside of the UK please remember that there may be import fees to pay directly to the delivery company before receiving the order. Unfortunately we can’t advise on the exact costs as it varies from country to country, so please check your national rates before purchasing.

Size - this is the manufacturer’s sizing and must match the size or your wheels. This can be confusing as tyres have had different sizing systems over the years, and there are many (sometimes conflicting) sizes available. For this reason it’s important to check the ISO diameter too for clarification, especially for 26” wheels.

Bike Type - the type of bike the tyres were designed to be used on. Road tyres will generally be narrow with minimal tread, touring tyres wider with a bit more grip in the tread, and cyclocross & MTB tyres wider still (especially the latter), with a much more pronounced tread pattern.

ISO Diameter - this relates to the diameter of the wheel rims at the point where the tyres are seated (bead seat diameter). This is a universal measurement, often displayed on tyres as 28-622 or similar, 28 referring to the tyre width and 622 being the ISO diameter in millimetres.

TPI - stands for threads per inch and refers to the thread count of the tyre casings. A high thread count usually means more supple and lighter tyres, this can be anything as high as 320 tpi. We can’t always provide this information however, as it’s not always possible to know for sure.

Cage Fixing - most bottle cages will be designed to fix to the frame, although some rare older ones mount to the handlebars and/or stem. If your frame doesn't have any bottle cage braze-ons to fix to you'll need a clamp-on bottle cage.

Capacity - 500ml used to be the standard sized bottle, but the taller modern versions tend to be 750ml.

Clamp Opening - the minimum and maximum distance between the inside of the nut and bolt heads. The minimum is measured with the bolt tightened as much as possible (for hex head types this may mean the bolt end will stick quite far out of the nut). For the maximum opening we ensure 5-6 mm of thread remainis in the nut for a secure fixing.

Outer Diameter - the part that goes through the frame, most steel frames will take an 8 mm bolt whereas early lugged aluminium frames often have a larger hole that takes a 10 mm bolt diameter.

Bolt Fixing Type - some binder bolts have tightening mechanisms on both sides to secure the seatpost in the frame. Single sided bolts need something else to help; some have knurled parts that grip the inside of the bolt hole, others have a small notched 'key' locator that lines up with a cut-out in the frame (if you have one).

Speed - the number of cogs on the freewheel.

Range - the number of teeth on the smalles and largest cogs, this gives you an indication of how hard or easy the gearing will be, the lower the number the harder the gears. The tooth count of the cogs inbetween are usually evenly spaced, ie: a 6 speed 14-24 freewheel would likely have cog sizes 14, 16, 18, 20, 22 & 24.

Threading - this needs to match the thread of your rear hub. ISO is the modern standard and is almost exactly the same as older English/British and Italian thread, allowing you to mix and match between these thread types as long as it's not going to be under extreme force, in which case it's best to stick to an exact match. Hubs with a French thread must be used with a French threaded freewheel.

Stack Height - the total height (or width if you're looking at it when installed) of the freewheel, this is measured from the base (back of the largest cog) to the top (front of the smallest cog).

Cog width - this is mainly relevant for singlespeed and some older 3 or 4 speed freewheels - if this is ⅛” then you must use a ⅛” chain, but most freewheels (especially multiple speed ones) will use a standard 3/32” chain.
