A complete range of bicycle components from top brands
Bearings are used to reduce the friction / wear between an object (such as a wheel) and the surface over which it moves (such as an axle)
Quality bearings these days are sealed (they used to be loose or in a wire cage)
If you would like to learn (a lot) more here is a really detailed explanation - please check out this learning pack from SKF - one of the leading manufacturers of bearings
Quality bottom brackets from Brompton, Hope, Shimano and SRAM
Brakes and brake related equipment (pads / cables / tools)
Cables are essential for controlling brakes and / or gears on your bike.
Chain related tools. Chain checkers, chain tools for breaking / making chains, chain whips.
Chainrings and complete chainsets
Bicycle chains and chain accessories / parts from Shimano and SRAM (previously known as Sachs)
Derailleurs are used to move the chain from one sprocket / cog to another
The derailleur hanger connects the rear derailleur to the frame of the bike
They are designed to break with less force than would be required to break the frame!
Brilliant Bikes keep rear derailleurs from Wheels Manufacturing - they are CNC machined in the USA and fit a wide range of bicycle manufacturers / models
Mountain bike frames from Intense and forks from RockShox (more and forks from Fox will be coming soon)
Sorry, we no longer sell Brompton frame parts (main frame, handlebar stem, rear frame and forks) online, as Brompton have requested that these are now a dealer fit only item.
Bicycle headsets and headset spares
Inner tubes are available in three value types:
Good quality air tight tubes have to be inflated less. This means you can get straight on with your ride, rather than messing around inflating the tyres before you can start. (or have an extra 10 minutes riding / in bed)
AV = Auto Valve - The wider valve generally used on lower end bikes and on Brompton folding bikes - these are in a blue box
SV = Sclaverand Valve - Referred to as a racing / presta valve in the UK - these tend to be used on higher end bikes where thinner / lighter wheels needed a narrower valve - these are in a red box
DV = Dunlop valve - not so common now, as they are a bit more fiddly to look after - these are in an orange box and are becoming less available
40mm - the normal / common presto valve length
50mm - long length
60mm - extra long length
80mm - extra extra long length - for deep carbon rim wheels
Derailleur / Chain tensioner jockey wheels from Hope (for Shimano and SRAM derailleurs), and Brompton
One of the most important parts on your bike (but often overlooked), pedals are just one of three contact points between you and your bike (along with the saddle and handlebars)
We keep a selection of pedals for road, mountain, leisure, kids and Brompton bikes in stock
Saddles are an important part of your bike - not to be under-esitmated
Just one of three contact points between you and the bike (along with pedals and handlebars)
Brilliant Bikes mainly stock saddles from Brooks of England and Brompton - two classic British brands
We can also get (at special request) saddles from Selle Italia and Selle Royal - and will shortly be carrying saddles from the ergonomically designed brand Ergon
Sprockets, cassettes and freewheels.
Wheels, including those for folding bicycles, spokes, dynamos, hubs and wheel accessories
Gear triggers / shifters
Ever since Mr Dunlop invented the pneumatic tyre, they have become an invaluable part of cycling life
Here at Brilliant Bikes we stock quality bicycle tyres for all types of bikes from folding bike (especially Brompton), classic (such as Pashley), commuter, all mountain, cross country, downhill, road and cruiser.
Getting the right size tyre for your bike is important - though not always as simple as it seems
To select the right size tyre, we suggest that you go by the ETRTO / ISO number (e.g. 37-349) which is printed on the side of the existing tyre - not by the size (e.g. 16 inch), as a description of 26 inch for example can refer to several different diameters.
For a full, in depth explanation of tyre sizing, you could check out this web page .... The Sheldon Brown guide to tyre sizing
