I used to use a Polar HRM and found that I would occasionally get a very high HR reading, 220 - 260bpm. My tested max is 186bpm (by cardiologist). Eventually figured out that the abnormal high reading was always on a downhill and was probably caused by my shirt flapping when the zip was down. Presume it could only be static?? When I had my shirt zipped up I never had a high reading. When I got the high reading if I stopped and physically measured my pulse it was always well below my 186bpm max. Also found that when the high reading showed I just needed to put my hand over the sensor and the reading would jump straight back down to a 'normal' reading. Have since changed over to a Garmin HRM and never had the high readings since (2 years). I think the Polar Wearlink chest strap doesn't fit me as well as the Garmin strap.

Ian - where did you get your AC rims from? Got them from Action Cycles here is PE.

I had the same decision to make and eventually went with the new American Classics Tubeless wheelset instead of the Mavics Crosstrail or Shimano XT sets. They are lighter and are in the same price range.

Got this from a post on Chit Chat forum: Vat is calculated at Cost of goods + 10% =R ? x14% = Vat Eg R1000 + 10% =R1100 x14% = R154.00 So, 15.4% would be correct.
