Hi again,
26-inch rims - are they basically all the same width? If so, does that
mean i can buy a tyre of any width to go on them? If not, how do i know
what widths i can buy? I've always assumed rims were a standard size, but
i've never actually had to buy new tyres before, so i've never thought
about it too hard.
Wait! Why don't i read Sheldon Brown's highly informative article [1] on
the subject? Aha - so there *are* different sizes of rim, and it does
matter.
So, what width do i have? The current gignormous knobblocalyptic tyres say
26 x 2.00, but i assume the 2.00 refers to the tyre, since the rims aren't
two inches wide. There's nothing written on the rim itself - it's just got
bloody Decathlon branding. Well, except 'Rigida' in tiny letters - a make,
but no model. A bit of googling suggests that it might be a Sphinx:

It's not a Taurus, since i don't have disc brakes. If it is a Sphinx, it
has an interior width of 16.8 mm, which according to Brown and Boeger's
table should accomodate a tyre 25-37 mm across; Rigida themselves say
25-48 mm. The tyres actually fitted claim to be 51 mm, which is a bit odd.
Am i on the right track here? Should i give up on buying new tyres and
just slickify my knobblies with some putty?
