Dubai is filled with the finest grains of sand I have ever come across, this sand is so fine that it manages to work its way into areas that would normally be considered sealed areas. The biggest issue faced by riders here is the upkeep of bottom brackets and chains. My advice is to have regular BB services a minimum of every three months or 1,500km, a regular service will help prevent unnecessary wear and tear due to sand abrasion. The next and most important part that needs to receive regular TLC would be the chain. The chain collects sand very easily this combined with the wrong lubricant will cause you more unnecessary expense. Personally I only use White Lightning Dry Wax lube in Dubai. White Lightning actually sheds dirt and sand build up. Wet lubes collect sand and form an abrasion paste that will wear your chain and cassette rings unnecessarily.
