First stupid question/s of many ! :oops:
Tyre pressures for a 13 stone me riding a carrera fury on tarmac and light trials
and ;
How do I pump them up ? I have a standard car type pump but the valves on the bike are tiny and don't fit, I've seen adaptors on ebay but don't know exactly which one I need
any help appreciated from a newb

There are two types of valve - Presta (smaller) and Schrader (larger). Cars and most mountain bikes have Schraeder valves. Some mountain bikes and most road bikes have Presta valves. You have Presta valves (don't worry, they are actually better - lighter and can deal with more pressure)
You either need to buy a pump which is compatible with Presta valves, this one does Presta and Schrader (I have one, its very good), or you can buy an adapter but I hear they are usually crap.
RE pressures: For paved surfaces and roads I would run 45-60 psi for better rolling, for trails and anything off road, drop to 25-35 psi for more grip.0 -
Perfect answer, thank you0

but they are at least 2 grams lighter than a schraeder.Fig rolls: proof that god loves cyclists and that she wants us to do another lap0 -

The are used on narrow rims so that they don't effect the strength of the rim too much.
Please show me a Presta valve in a high pressure use.
Shocks? Nope.
