Help! Oktos MP 9, no manual.

swimmersara

Hi there. I'm new to this group and new to cycling in general. I'm a swimmer. I've got a lot to learn about all this technology you cyclists use since I am training for my first triathlon.

I just bought a road bike (Specialized Allez Elite); been training on a Raleigh M80 with slicks for 2 months, so I'm pretty excited to switch over. Years ago, a friend mounted my Oktos MP 9 on my Raleigh. Now I want to switch it over. I see how it is mounted up top, and to the front fork, and where the magnet is attached on a front wheel spoke. I can move all these things, but I have no idea how to reprogram the computer for my road wheels, and I cannot find my manual anywhere. Help!

Thanks Scotty Dog!

Those instructions are right on. My only question now is, do you know where I find the code for my road bike wheels (622x14 is what I see on them). Current code 2074 was for my mtn bike wheels.

I promise I can answer all your swimming equipment questions...

Your previous code 2074 is a reference to the circumference of the tire in millimeters.

You need to determine the circumference of the tire the sensor is now located on. You can use this chart and look up the circumference for your tire size, then enter the number on the far right side of the chart into your cycle computer. To be even more accurate, you could perform a rollout test to determine the actual tire circumference.

FYI: The number you gave me before, 622-14, is the rim size, not the tire size. Look on the sidewall of the tire to determine the actual tire size. For example, 700x23, 700x25, etc.

Sara,
Please describe your swimming equipment. Pictures are optional.

Thanks again, it was indeed 700x23. I've learned a lot already from this, so thank you!

I find now that there's not a lot of space between the fork and the spokes, compared to my old bike, so that the magnet rubs a little as it goes around each time. Tried fiddling some, making it a bit off-center of the receiver bit since that part bit is not uniform in thickness, but didn't get it far enough to stop rubbing entirely. I assume this is bad.

I'll be riding with some folks later on today and see if any of them has some fiddling ideas. Already made an OK solution to making bit that sits on the handlebars fit (mtn bike handlebars were not as thick). Reminds me of car repairs back in my days in the Peace Corps --there's nothing that baling wire can't fix! Same goes for zip-ties.
