  Bearings

  Bearings

  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

  We sell bearings from Enduro / Hope / Orbea and Intense
  (The Intense / Hope and Orbea bearings are actually made by Enduro!)
  
  Unlike some other bearing manufacturers, Enduro bearings are not just ‘off the shelf’ Industrial bearings.

  Enduro say their bearings are tailor made specifically for the demands of cycling.

  Every aspect of an Enduro bearing is considered and specified to provide superior performance and value for each application, from the material of the races and the ball bearings, the types of seal and even the grease.

  Each of these considerations has a pronounced effect of the performance and longevity of the bearing.

  Enduro ABEC-3	Grade 10 Chromium Steel Balls 52100 High Carbon Chromium Alloy Races Riveted Steel Retainer for toughness, ABEC-3 tolerances and noise tested, C-3 or C-N Internal Clearance Seals on these bearings are usually blue
  Enduro MAX	Maximum quantity of Grade 10 Chromium Steel Ball 52100 High Carbon Chromium Alloy Races LLU Seals: Two sealing lips on each seal, which ride in a matching groove on the inner race to make a labyrinth seal.
  Enduro ABEC-5	Grade 5 Chromium Steel Balls 52100 high Carbon Chromium Alloy Races - ABEC-5 standard Graphite/Nylon Ball Retainers
  Ceramic Hybrid	Grade 5 Silicon Nitride (Si3n4) balls ABEC-5 chromium steel races LLB Seals
  Zero Ceramic	Grade 3, Silicon Nitride (Si3n4) Balls. Races are treated with a black oxide coating then reground to a mirror finish. Finally, they are cryogenically treated for strength before assembly. Silicone VV seals, which is the lightest drag seal available on the market.

  Bearing seals

  Various different seals help prevent ingress of water / dirt into the bearings in different degrees

  • Open side bearings

  Some are left open - so grease can be topped up via a grease port

  • LLB - is a double lip type labyrinth bearing - making light contact
  • LLU - is also a double lip type labyrinth bearing - making medium contact
•

  Chainrings

  Chainrings from our favourite manufacturers including:

  • Hope
  • Bompton
  • SRAM
  • Shimano
  • Sunrace

  You can often change the gearing on your bike by just replacing the front chainring with a compatible alternative (smaller ring for easier climbing or larger ring for faster on the flats)

  Hope

  Hope produce a range of chainrings for different fittings and now available in 7 different colour options:

  • Black
  • Blue
  • Orange
  • Purple
  • Red
  • Silver
  • Bronze (new for 2024)

  Brompton

  The introduction of the "spider" chainring means that it is easier to change the colour or size of a A Line / C Line / P Line Brompton folding bike with a choice of 2 colours:

  • Black
  • Silver

  and a choice of 3 chainring sizes:

  • 44T
  • 50T
  • 54T

  You can use the Brompton gear calculator page to see the effect of changing chainring: http://xldev.co.uk/bgc.html

  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

  This (as of 2019) is a new category for us where we will start to list the electronic components - such as Shimano Di2 and SRAM AXS

• 

  Frames and Forks

  Mountain bike frames from Intense and forks from RockShox (more and forks from Fox will be coming soon)

  Inner Tubes

  Bicycle inner tubes of quality are worth having!

  Inner tubes are available in three value types:

  • Presta / Racing
  • Schrader / Car / Auto
  • Woods / Dunlop (these are actually still the most popular worldwide, but not used much in the UK)

  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)

  Schwalbe tubes use the following prefix for different type of valve:

  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

  Presta valves come in different lengths (they may vary slightly by manufacturer):

  40mm - the normal / common presto valve length
  50mm - long length
  60mm - extra long length
  80mm - extra extra long length - for deep carbon rim wheels

  Jockey Wheels

  Jockey Wheels

  Derailleur / Chain tensioner jockey wheels from Hope (for Shimano and SRAM derailleurs), and Brompton

• 

  Pedals

  Bicycle Pedals

  In our opinion, pedals are one of the most important parts on your bike (but often overlooked)

  Contact points

  In fact, pedals are just one of three contact points between you and your bike (along with the saddle and handlebars) - and if your standing, then make that just two!

  Pedals for all disciplines

  We keep a selection of pedals for road, mountain, leisure, kids and Brompton folding bikes in stock from Brompton, Hope, MKS, Shimano and crankbrothers

• 

  Saddles

  Bicycle saddles

  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

  Sprockets, cassettes and freewheels

  We keep a selection of sprockets / cassettes / freewheels from:

  • Brompton (of course)

  • Shimano
  • SRAM
  • Hope
  • Campagnolo
  • Sunrise Sturmey Archer

  for use on:

  • Brompton folding bikes
  • Road bikes
  • Mountain bikes
  • Hybrid

  Cassettes have been in short supply over the last year or two (as at 2022) and this continues to be the case with some (for example the Shimano SLX 12 speed) not available until 2023

  Tyres

  Bike tyres

  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.

  Selecting the correct tyre size for your bike

  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

  If in doubt you could contact us here at Brilliant Bikes
