Continental Ruban Wire Bead 27.5" Tyre
The energy-saving SUV allrounder that gets you to both Rural and Urban. The partner for your commute, running errands and the weekend tour.
The advanced new compound
Based on activated silica compounds, this technology was originally intended as an performance level compound, but after intensive development at our Korbach Research and Development Department Facility, an advanced new compound with outstanding grip and cross-country properties was developed. This new rubber mix, given the self explanatory name “PureGrip”, is ranked just behind our BlackChili Compound and is being used in our performance products both in the road and mountain bike sectors. Whilst providing great grip, it is also long lasting and highly durable – both characteristics of Continental tires, which are exclusively manufactured in the factory in Hefei (Asia).
Occasionally, without notice, manufacturers change product design and/or specifications.

How to check your current tyre size?
Take a look at the sidewall of your current tyres and you’ll see one or two sets of figures;
One is the traditional size like 700x28c or 27.5x2.2. The first figure is the tyre diameter(size). The second is tyre width. Note: road bike sizes are in mm, MTB sizes are in inches.
The other set of figures you may see is ETRTO sizing like this 28-622. The first number here is tyre width while the second number relates to wheel diameter.
Here is a comparrison chart for traditional and ETRTO sizing to help you choose the correct tyre size.

Will this tyre fit my wheel?
Your new tyre must be the same diameter as your current one (to fit your wheel rim).
Then, you need a choose a tyre which will fit your frame.
Road bike tyres are generally 21 – 28mm wide
MTB tyres can range from 1.5”-5”
To make things complicated road tyres are measured in mm, while MTB tyres are in inches.
How wide is too wide
You want to leave at least 4mm clearance between your frame and tyres to prevent rub and allow for mud clearance.
Measure the following areas on your frame:
Fork crown (top)
Brake calipers (make sure you squeeze them)
Chainstays
Seatstays
Subtract 4mm and you’ll have the maximum width your frame can handle.

Continental Ruban Wire Bead 27.5" Tyre
I chose the Conti Ruban tyres for a 650b conversion on my bike for the winter and couldn't be happier. I live out in the sticks and commute into the city along an old railway path and the Rubans handle the mud, grit and standing water pefectly. Bike feels incredibly stable in slippery conditions, and *I* feel much safer going in towards the winter, especially as we start to get to more icy or slushy conditions down on the line.
