For the last couple of months I have been doing some research into what I might like on a new mountain bike. To put this into context my existing bike is about 8 years old, and although it is in good condition there have been a number of advances in bike technology that I would like to take advantage of. Although vanity would probably rank quite highly as a reason for this, I also want to make a good buying decision and get the best bike for the money I am willing to spend.

   As part of this deciding process I have had to work out the advantages of having various items on the bike, and if for me they are worth the expense. Some of this I have accomplished through actually renting a decent mountain bike and giving it a good ride to understand the differences in handling. The rest has been through reading the opinions of others on the internet and in magazines.

   One thing has become very apparent; there is a lot of misinformation out there, a lack of basic understanding of mechanics and physics. And of course the usual urban myths recycled by manufacturers willing to pander to them.

   You always get this in any Geek culture, but I think Cycling in all its forms produces more misinformation than other areas of geekdom that I have been involved in.

   An enquiring mind has led me to get to the bottom of the inaccuracies that interest me, using a process of quasi scientific experimentation or the application of common sense and in depth research.

   I will be publishing my findings and the more unconventional proofs here in due course. These include examining tyre choice on tarmac roads, effectiveness of conventional cantilever brakes, adjustments and how to use/abuse them, my personal necessity for disc brakes, Weight, cycle lights, suspension penalties. This gives plenty of room for the usual controversial talking points to rear their heads.
