View Full Version : Cyclometer for a Tadpole? [A question of length]

Anybody here run a cylometer on their Tadpole? I've got the Actionbent Tadpole but my cylometer from my old (& now gone) mountain bike doesn't have a long enough wire to reach all the way from the rear wheel to the bars. Sure, I could probably just hack the wire and splice something in to make it longer, but I'm not sure I wouldn't lose accuracy if I did.
Also (if you do have a cyclometer) where/how did you mount the sensor? The rear forks don't come too close to the wheel.

I thought I heard somebody mention a wireless cyclometer???

A wireless computer might work, but even those have limited range. Some people have had success, others have not.

There are two other options. The first, as you mentioned, is to splice in an extra length if wire. Unless you're handy with a soldering wire, and can solder very thin gauge wire, I wouldn't suggest it.

The other thing to do is to look for a replacement wire/cradle from the manufacturer. I know that Cateye sell a "long wire" version of some of its cradles for just this purpose.

Lengthen using wire of a similar gauge. Tin the conductors prior to joining them. Warm the conductor until a little solder flows onto and into the strands. Repeat for both joins. Then align the conductors. (A bit of a twist will do) and heat the joint momentarily. The solder will run together. Remove the heat and let the joint cool. Don't move the conductors until the solder sets. I find a magnifier stand works well. Insulate the join and then repeat for the second conductor. Remember to insulate the entire wire once the second join has been made. Shrink wrap tubing works best. Do likewise for both ends of the splice.

Why not attach your sensor to the front wheel?

I thouht about that, but there's no room between the brake rotor and the spokes to mount the sensor and there's no fender to run the wire from and keep it off the tire. I suppose I could get a wireless model....

I have a GT3 and run the sensor on the front wheel off the mirror post, in my experience wireless will have range issues from the back wheel.

The mechanic I talked to said to run it from the rear wheel. That's what he does on his trike. If you don't want to solder, buy a long wire kit. Most of the name brand computers offer it as an option.

I run a Polar S720i cycle computer on my Micro, both cadence and speed are wireless and work quite well once you adjust the strength of the signal. I have the cadence pickup on the boom and the speed pickup setup for the rear wheel. It took a little bit of trial and error, but once the distances where set to maximum on the transmitters and the transmitters also placed as close to the receiver (the S720i) as possible, the results are great - no wires to worry about and battery life isn't too bad - going on 2 years (will replace the batteries in January).

One of Trek's "Incite" models (9im or 8im I think) Has an extra-long wire.

I have a WhizWheelz TTS and am using an old style Topeak Panoram (the wide one) with a long wire reading off the rear wheel. I had to build up my chainstay for the sensor to be close enough to the magnet. Problem is I don't think the wide Panoram is available any more. If you can find one, I'd snatch it up.

I see they're still listed on the Hostel Shoppe's online catalog. I've got one of those too. Nice computer.

I ran a wired CatEye with long harness (Hostelshoppe sells long harnesses) to the rear wheel of my Terratrike. Worked out ok. I know of people who have devised little extenders to run wireless units to their front wheels as well.

I finally said to heck with computers and got a Garmin Fortrex 101 GPS. End of fooling with wires, sensors coming off or shifting, etc. on multiple bikes. Now I just strap it on and go on any of my bikes. Comes with a bike mount or velcro strap for the wrist. I find the velcro strap works fine by strapping it on the frame somewhere, or the handlebar, depending on what you are riding.
