Can anyone give me a good suggestion for a rear wheel cycling computer. None of my local shops carry them and its driving me crazy not knowing how far or fast I'm going on my trainer

1. if the cable isnt to short you can route it to your rear-wheel(try using the top tube, thats shorter🙂.
2. Otherwise you could order a cateye astrale.

Best computer out there I think ......... have used one for years. Has cadence as well, big plus for me as I try to always ride at 90+ for cadence.

You can fleabay them for about $25-30 or so I think.

only the old astrales have a rear-wheel sensor... the newer astrale 8's have a front wheel sensor. i love it, but it doesn't do me much good on the trainer.

i think you can get the old ones at performancebike.com for now. or you can get their axiom (performance brand) computer. the one with cadence also has a rear wheel sensor. nashbar might make a similar one too... all these are <$30.

good luck.

No, the newest ones have the rear wheel sensor, so apparently they went back to it. If you have one with a front wheel sensor, go to the Cateye website (www.cateye.com), and order a wiring harness kit for the Astrale (~$15). Your new kit will have the rear sensor.

The way I got around the problem with my computer (Sigma BC1400) was to cut the wire and put an extra length of wire in there. Crude but effective, and something I'd only consider doing with the Sigma BC1400 which I love. Any other computer can get stuffed. 😉

I was going to say, I just bought mine last year .........

VDU used to make one with cadence included , don´t know if it´s still available .

Maybe a silly question -- what's the difference between a rear-wheel sensor vs. a front-wheel sensor besides the wire length? If I bought the old Astrale from eBay, why couldn't I mount the sensor on the front wheel?

Thanks.

Wire length is the only difference.

If you have the kit with the long wire, you have the option of front or rear wheel mount. If you have the short wire, you have no option other than a front wheel sensor mount.

Just thought I add my 2 cents here...

I use a Vetta 100HR (front wheel) on both my current road bikes... However both use the wireless sensor. So... I tried to use the wireless on the backwheel last weekend.

Fuggedaboudit ! Line of sight from the sensor to the handlebar unit, distance, interference, I dunno... Doesn't pick up the signal. I think I'll check out that Cateye Astrale, seems like a sensible choice. I can always use an extra HR monitor.

I also use the Vetta 100HR, but I suspected the 100% wireless option might be prone to trouble, so I bought the wired setup for BOTH speed and cadence, and it works *perfectly*.

I have been using the CatEye Australe for about 12 years. Original computer and I have purchased additional installation kits for road (training), road (race), track and trainer bikes.

From my experiences, do not run the cable from the rear wheel/ cadence sensors under the bottom bracket and under the down tube. It looks neat and out of sight but prone to damage from objects thrown up by the front wheel.

Testimony is my track and trainer bikes have original installation kits but my two road bikes have had replacements until I twigged to running the wires in a more protected but less glamorous position.
