When the preferred wheel size is not listed in the preset list, select CUSTOM. It is possible to set the ODOMETER data into your new bicycle computer.
It's probably something they've considered more carefully than you might think. I tried to explain this to a friend, and his reply was "your inner nerd is showing," which is probably true. But, I have degrees in math, computerr I don't care. My computer sensor reads off my back wheel, which carries most of my weight.
So when I measure the circumference of the tire, that must be taken into account. There is, effectively, a loaded and unloaded circumference. In my case, the unloaded setting wheel size for bike computer of a new x25C Gatorskin is about mm.
The loaded circumference is around mm. With miles on the rear tire, it's squared off pretty whefl, and the worn unloaded circumference is about mm, whereas the worn loaded circumference is around mm.
These tires are typically good for miles, maybe Near the end of its life, the number given by Cateye turns out to be pretty close for this tire. But not all tires of a given size have the same setting wheel size for bike computer. Schwalbe Marathon Plus tires, for example, are taller larger circumference than Gatorskins.
Over the life of the tire, this would cause my speed and mileage compuyer be overestimated when the tire is new and underestimated when the tire is worn, but it should average out by the time the tire is replaced, assuming the tire achieves an average lifespan.
I'm assuming that when you say the "wheel" has a size of x15c listed on it, computfr mean the rim and not the tire. As others have mentioned, the tire size is what setting wheel size for bike computer need.
Almost any c tire will fit on your rim, assuming that your frame has the clearance to accommodate it. Once you've got your tire on there, check the size listed on sports watch gps cycling and match it up with the sizes you've listed.
It's worth noting that any xwhatever tire will not necessarily be exactly the same size as other tires with the same size listed on them.
The size is an estimate. If you want setting wheel size for bike computer most exact measurement possible, aetting if your tire size isn't listed, you can measure it yourself like so:. Put a chalk mark on the ground. Position your front wheel directly on top of the chalk mark with the valve as low as it will go, which means it will also be directly on top of bike gps security system india chalk mark.
With the chalk in your hand, roll the bike along one full tire rotation until the valve comes to rest at it's lowest position. Put another chalk mark.
Measure the distance in millimeters. Use that number instead of whatever the chart tells you. And, if you want the most precise measurement possible, sit on your bike while you roll it along and get a friend to do the marking.
This wall account for the way your weight distorts the tire. Incidentally, this measurement process is all explained in the manuals of most cycle computers, page 24 of your particular manual. Another method would be to mark the ground and tire with chalk where the tire hits, find wheel size for bike computer the bike forward and mark setting wheel size for bike computer it hits again.
Wondering if all Radrovers with 26X4 wheel should be set to 28"?
Drew Active Member Jun 19, So, no doubt 28" is more accurate than 26", because you are not rolling on the rims of your wheels! But there it may be there's an even closer setting.
With fat tires you may setting wheel size for bike computer to devise some way to measure the diameter taking into account the amount of tire "squish" you get when riding at your usual pressure. Last edited: Jun 19, I think will adjust both of my Radrovers to the 28" wheel size since that seems to match up with external sources I see when riding.
Comes out to 88" circumference as the outside diameter making contact with the ground with my weight on it. I added an external odometer and needed to figure out the wheel size in mm.
The external odometer is spot on with other external mph sources also. Ebikefevercure Active Member Jun 20, Tire pressure will alter your reads as well. By Richard Hallett Thursday, 5 July Are you confused by the markings on your tyres? Tyre size table The table below lists most of the sizes of tyre that are likely to setting wheel size for bike computer found in the UK.
Tubeless tyres Tubeless tyres, as the name suggests, do away with an inner tube and, in setting wheel size for bike computer absence, are reliant on the shape and tightness of the tyre bead to ensure the tyre does not blow off the rim at high inflation pressures; bike computer for cadence lixada a conventional clincher tyre, the inner tube keeps the bead securely located under the rim hook.
It is inadvisable to use non-tubeless tyres without an inner tube as there is otherwise a risk of tyre blow-off. Tubular tyres Used primarily for racing, tubular tyres must be fixed to an appropriate rim using glue, cement or adhesive tape. Recommended pressures All tyres are marked with a pressure.
