Cycling Computers

[dannyfrankszzz]

I've recently just fitted a cordless Sigma 1200 + RDS to my bike. I haven't actually gone out for a ride with it yet but so far I can't say I'm impressed.

Firstly, the computer is attached to the bike by rubber bands??? That's the attachment that goes on the handlebar and the transmitter attached to the forks. This doesn't inspire confidence both for security or for secure fitting. Also, the fitting that attaches to the spoke, which the fork sensor is supposed to detect before it sends the signal up to the computer that a revolution has completed, is made of a flimsy rubber with a flimsy metal attachment, which doesn't look like it will last very long. Frankly, the design looks and feels very cheap.

I've used a Cateye Cordless before and thought I'd give this Sigma a go but what an error that turned out to be! If I remember rightly, the Cateye is attached by use of pull ties, which are far superior to rubber bands!!!!!

On the plus side though, the computer functions are a little simpler to understand than for the Cateye.

I've been using this attachment for about 6 years no,
no problem.

Mmm, haven't seen this before. Sigma magnets are usually a
plastic barrel with a hole through the middle for the spoke.
A metal sleeve pushes over the plastic barrel to close it
tight onto the spoke. I've actually purchased the Sigma
magnets separately to use on other computers because they
are so good.

There is a bit of double sided sticky tape for the handlebar
as well. It's pretty solid.

12 years and counting for my BC600. I did replace the rubber
band after 11 years when it broke

Never had any problems. I find it pretty tough to get off
when I have to remove it. I have sensors on 3 bikes.

Sigma sent me a new instruction booklet for my BC700 by
return of post - 11 years after I bought it. I was impressed
and bought a BC1600 when I next needed a new one.

I use a Sigma BC 1600 and was initially not impressed by
the rubber bands, but having used it for 6 months, it is
better than my old Cateye system. No slippage and a good
reliable computer.

OK, well your comments have made me slightly more at ease. I'll use the computer for a few months and see how I feel.

The other thing that irks me about this purchase is that Cycling Plus magazine gave it a 10/10 review, which is basically what convinced me to buy it.

However well the computer performs in practice, the rubber bands make the product inferior to the Cateye.

and the Cateye is only slightly better with nylon ties. I
wan the screw on fixings back so I can remove it all for
cleaning and adjust position.

You forgot to add "in my opinion".

Not necessary when it can't be anything else. That's usenet,
a whole wodge of opinion, if you can't filter out the wheat
from the chaff, you're stuffed, and in life generally. Sorry
that sounded really harsh, that wasn't the intent, but I
can't be arsed to rephrase it.

That's the other thing about Usenet, you can word your posts
as you like!

No problem here anyway

<<You forgot to add "in my opinion">>

Errrrr, no, I didn't forget. My opinion here happens to be the infallible truth.

RUBBER BANDS ARE INFERIOR TO PULL-TIES!

I think thou shalt agree.

Well, it's obviously *his* opinion - rather than
someone else's.

IME Sigmas are excellent - and waterproof too, but
personally I'd get a wired mounting kit (Gearshift sell them
separately for about a fiver) and forget the cordless
gubbins, unless you have suspension forks or some other
compelling reason for using cordless. The rattling of the
motion switch finally drove me mad.

I shan't. Rubber bands for fixing computers are the ideal
choice for a computer that is moved from one bike to
another. DH has a computer where both the display and the
sensor are attached by rubber bands. It's a 2 minute job
to take it off his bike so that it can be put on hire
bikes on holiday.

Rubber bands rule!

I reckon most people go for cordless for aesthetic reasons.
That my opinion of course

I've never used a 'corded' one. Do they not have a
'motion' switch'?

Since when is a suspension fork a compelling reason for
using cordless? I've guided the cord of my Sigma BC 1200
(indeed, a very good make of cycle computer) via the disc
brake line to the fork leg. The brake line will (by
definition) always reach to the wheel and will move with the
suspension movement. I've had no problems until now and
we're talking about a 110 mm. fork here.

I have recently bought a road bike having ridden mtb's for some time. I use a really basic cateye computer, a MITY 300, which is really just a speedo but for the moment it's all I need. The problem is I need to reset it to match the diametre of the wheels of the new bike and that safe storage space for the book of words that came with it has so far eluded me. The thing works by entering a code number between 100 and 300 which then corresponds to the wheel size. The new bike runs on 700 - 23 (23 - 622) tyres, if anyone has any ideas I would be grateful! Cheers, Ben

CatEye computers always used to ask for the *circumference*.
If you're using tyres which are *actually* 700x23, then this
will be 210cm (pi x diameter = pi[62.2+[2x2.3]]). Tyre sizes
are often pretty nominal, though - I'd measure them, which
is very simple - just roll the bike along a tape measure
laid out on the ground, measuring one wheel revolution from
valve to valve, if you see what I mean.

I think 210 might be your number.
