27" Wheels. Are they a thing of the past?

[Slowgrind]

My ancient steed has 27"*1.25" wheels. Asking at my L.B.S. for new wheels and tyres I`m told that I can`t get them these days. Does anyone Know different? Halfords have some horrendous road tyres in this size but I can`t seem to find any others locally.

Try a large 'BikeHut' at Halfords.

They had, I say "had" 27 x 1 1/4" wheels last year.

The rims were single thickness clinchers. The hubs and spokes were crap, but that doesn't stop the rims being built onto decent hubs.

They were quite cheap ( monetary ) so if you are looking for 27" High Pressures, try BikeHut.

PS The single thickness rims will prob' be lighter than double thickness 700C rims.

27" x 1" HP clinchers are still out there. Find and buy what you can.

THere is an interesting page o nthe CTC Website explaining tyres and sized, which can be applied to wheels.

Most tyres are now marked according to the International Standards Organisation (ISO) in addition to more familiar markings. The ISO size comprises two numbers separated by a dash. The three-digit number after the dash is the most important. This is the bead diameter at which the tyre fits onto the rim. Check the bead diameter of the tyres on your bike. If you’re ever in desperate need of a tyre and can find one with the same bead diameter, it will probably fit even if every other thing about it is different.

That initial two-digit number is the tyre section and roughly indicates the tyre width. Its actual width is normally less, but varies according to how the tyre is designed and the width of rim to which it is fitted. But the height of the tyre usually corresponds quite closely to tyre section, so overall diameter approximately equals the bead diameter plus twice the section. That’s how the diameter and circumference (Circ. – equals distance rolled in one turn of the wheel) are calculated in the Tyre Size Table. These figures are useful for setting your cycle-computer and precisely calculating gears.

Half of the bead diameter (i.e. the bead radius) corresponds with the distance from the centre of the wheel to the centre of a brake block. By comparing this dimension you can see if the brakes will reach when a different size of rim is fitted to your bike. Switching from 630 to 622 for example, needs another 4mm of brake reach.

This is exactly the change in dimension you are looking for.

Depending upon finances the stages I would take in your situation would be...

Examine brakes and see if there is a 4 mm adjustment possible

Buy a pair of decent touring wheels at 700c (Edited - SPA cycles have been brilliant for my wheels)

Fit and enjoy the wide range of tyres at this size

Of course if the brakes cannot adjust etc then this may be even more expensive.

Otherwise go to s "specialist dealer" such as St John Street who have a range of "630" tyres including the Continental Gatorskins and Pasela tyres in 32 mm diameter

Hope this helps.

27 x 1 1/8 are apparently even rarer, but they are still available online from Spa Cycles, and Madgetts Cycles.

27" wheels and tyres are available in a variety of sizes from trade wholesalers - your LBS is just being lazy.

Try St Johns Cycles or Edinburgh Cycle Co-operative. http://www.sjscycles.co.uk/product-...ilver-Alloy-Rim-32-Hole--Box-Section-3268.htm

27" Wheels. Are they a thing of the past?

as an honest answer yes. But small amounts of stuff still available as mentioned above. Personally I am not into old bikes, and I prefer more modern stuff, so 700s are what I go for - gives much more choice. Also means less hassle abroad

+1. I ditched my 27's for 700c's (and made the necessary brake adjustments) in order to be able to get spares anywhere and at reasonable cost.

Ok trivia fans, who can name the last manufacturer to sell a 27'' wheeled bicycle in the UK?

A quick browse at Chain Reaction, and they have 27 x 1 1/4 in stock from Continental, Michelin and Schwalbe in racing, touring and commuting styles.

Getting tyres shouldn't be a problem at all, for now.

 

[tyred]

What you are looking for in modern terms is a 630-32 and should be easily available.

Hawk cycles had a 27" wheel 'thing' from China about 2 years ago. Can't find it on their website.
Either not featured on website, or stopped importing it.

Tyres readilly available as pointed out earlier, wheels should be reasdonably easy to geet too though choice is limited somewhat - ie for lightweight wheels you may have to look hard. I'm sure you can get good rims though and have them built up on whatever hub takes your fancy. My (soon to be winter only) commuter is 27"

To use 700c wheels you may just need to change to long drop brakes (alongha, tektro do a variety too) - these brakes seem to work well though not as good as the mavic ssc brakes on my roadbike!


I think if I had a 27" frame and no wheels I'd go for the long drop brakes and 700c wheels myself, but as has been said most bike shops can get them no bother, well you might have difficulty getting one equipped for a casette hub in an emergency......
