HRMs

Any HRM recommendations out there? I tried and did not like the Polar M21 HRM. I found it difficult
to start and stop. Erratic when functioning. I could not complete a single ride without the HRM
producing readings well above 250 and usually, when it hit HRs above 200, it would never return to a
normal range. (which killed any useful training data). Polar suggested that it was getting
electrical interference. Are there HRMs that are no so sensitive to common electrical fields
commonly found while outside on a recumbent?

One other thing that I discovered about the Polar HRM is that the HR sensor requires a trip to the
factory for a new battery.

Any one have a particular HRM that has proven reliable and gives useful information?

This sounds pretty much like the type of experience that I have had with HRM's, Cletus.

My personal theory is that they only work on 'some' people.

Maybe its related to the way an individual is 'wired'?

I've been using Axiom for a few months and it works fine. For about $100 you can get the axiom that
gives you all the functions(and more) of a polar that cost $170. Axiom can be bought from the
performance catalog. (www.performancebike.com).

Cletus In practice there is little that causes the signal to drop. One of my favorite rides has
about a half mile next to a high voltage transmission line that is only area that I know the signal
will be lost. And the new timing system at the races does cause trouble. Otherwise it works great.
Years ago before wireless, the chest strap was hard wired straight to the display. That was a bigger
problem. Didn't drop the signal though. Steve

Cletus's most recently acquired bike is an AL 'baton' bike! %^) It probably acts as an antennae for
all the EMI that's darn-near- everywhere and made his Polar M21 HRM unusable.

The BikeE is an AL 'beam' bike. %^o But it has an open port in the back to direct the EMI at the
unsuspecting roadies who regularly pass it. With the appropriate driver it would also make an
excellent subwoofer.

The Tour Easy frame has triangles, lots of triangles!

- Pyramids have triangles, and pyramids focus 'good
cosmic energy'. (Everyone knows this!)

- Therefore the Tour Easy frame creates a zone of good energy displacing EMI that would otherwise
cause my HRM to miscount.

- The parabolic reflector I carry on the front of the bike helps direct the good energy from the
frame onto me. (It's clear so that the displaced bad energy can pass through.)

The tin-foil h*lm*t liner is strictly a fashion statement. It does protect me from "Spiney Norman",
the giant hedgehog, however, when he's haunting Dimsdale Pirrahna.

I bet that's not legal in all states.

Where does one find tin foil - I can only find aluminum/aluminium foil?

Okay I'll ask...How do you wrap a shrink around your front wheel and if you manage to do it we
want pictures.

dunno, here we only have "silver paper" :-(. You have photo of aluminium foil?

I believe the Bacchetta Giro frame is made from 4130 Cro-Moly steel.

I've seen a couple of web references to using shrink-wrap plastic to make wheel covers... Here's one
such site:
