What number to enter into my cateye strada

Coriander

Hi,

OK, bear with me, I'm doing all this from memory as my bike is at home along with my busted wireless router so I can't look at thte bike now and I can't get on the Forum this evening.

I had to change the battery in my cateye computer recently and therefore have had to reset the whole thing. The problem is I never know what number to enter for my wheel size as it doesn't appear in that little chart.

From memory my wheels are 28x1 5/8 x something else. Or 622 and something... Or something else altogether. I have a Tricross Sport.

I am being truly pathetic, I know. Any ideas what number to enter - the 622 possibiity gives two numbers and neither exactly matches what my tyre says??

Please.

Does this make any sense at all...???

You need to physically measure your own wheel if you want the correct speed, the chart that comes with the computer is only a guide and varies depending on tyre fitted.

Indeedy, pump the tyre up to the normal pressure, place a marker on the ground, for example where the tyre valve is, and wheel the bike forward one rotation, until the valve is back at the same position.

Mark again, and measure the distance.

Voila

Have a read here: http://www.sheldonbrown.com/tire_sizing.html should help. I wouldn't bother faffing about measuring yourself.

Thanks UPL, but I have that table at home. And the numbers it offers don't appear on my tyre. That's why I get so confused.

Ah, I see....

Can't find my strada instuctions but these are from my Vectra, hope it's what you need.

18-622=207,
20-622=209,
23-622=210,
25-622=211,
28-622=214,
32-622=216,
37-622=217.

According to Evans your tyres are 700x32, so that makes them 32-622 =216.

Thanks for the help guys. I'm feeling particularly pathetic and useless this week (men suck, oh yes) so might just bring the 'puter and the bike along to SCR drinks tomorrow evening and throw myself on the mercy of the uber intelligent and kind people who'll be there.

You've been warned.

Cori,

Tricross sports seem to come with 700x32c tyres. If those are what you have then I think the number you're looking for is 2155.

The Vectra number (216) is the same figure in cm instead of mm. You will probably know which is right!!

If you've changed your tyres, then we need to know what size the new ones are before we can help, unless you want to get the chalk & tape measure out.

Cheers,
W.

Do it. Beer-advice is the way forward.

As long as said advice is solicited before too many beers have been consumed...

Surely that defeats the purpose of good beer advice!

@Coriander, if your not going to measure it, chalk and tape fashion, just enter the figure given above, it'll be about close enough anyway.

I have a cateye AND a Tricross Sport !

You need to enter 2160 for the correct circumference

redvee

Do the set-up after the beers, it'll be a lot more fun when you see your speed in 3 figures

being half asleep as I was when I typed the orignal message - I decided to recheck.

It's actually 2155 (got the checksheet with me)
