Description

Schwalbe's Extra Light butyl inner tube for 700c and 27in wheels, with a Presta (Sclaverand) valve. It saves weight over a standard tube. One Schwalbe tube covers a spread of tyre widths, so this one fits 700x23c up to 700x28c, and 27x1.00.

ETRTO 23/28-622/630
Presta valve, 80mm
Weight 70g

Schwalbe restrict the Extra Light no. 20 tube to rims with a maximum inner rim width of 19mm (19C). On wider rims they recommend the standard no. 15 tube, our SV15, instead.

Not sure of your size? The ETRTO number is printed on the sidewall of your tyre, for example 25-622. Match the rim figure to the one above and check your tyre width falls inside the range. If you are unsure, bring the wheel or your old tube in to us at 176 Saltmarket and we will match it.

Why Buy From Us?

Free servicing, priority workshop and bike box hire

Selling bikes in Glasgow since 1980 — one of the longest-established shops in Scotland.

Built properly. Every bike assembled from scratch by our Cytech Level 2 mechanics, brakes bedded in, greased to suit a Glasgow winter, buddy-checked and test ridden before it’s boxed.

Free 6-week service. Cables stretch and spokes bed in over the first few hundred miles. Bring it back and we’ll re-tension, re-index and check every bolt.

Priority workshop, for as long as you own the bike. We never turn away someone who bought their bike here, however busy we are.

Free bike box hire. A hard-case Bike Box Alan whenever you travel with the bike.

Free changes at the build stage. Saddle, stem, bars, tyres, pedals — far cheaper before the bike is built than after. Add a note to your order at checkout.

Free test rides around Glasgow Green, on as many bikes as you like.
