I have a Boardman MX Race Hybrid and it comes with Schwalbe Tyrago 700c x 37c tyres. I've got a long ride coming up which is mainly on road and was thinking about getting some thinner tyres, maybe 700c x 28c.
Does anyone know what the thinnest tyre size the Boardman MX Race can handle?
You should be safe to go down to 28mm, possibly 25mm. Keep in mind that though you'll be going on the road for a long ride, you might be feeling cracks and the road more with a thinner tire than versus a wider tire. 28mm should be fine, though.
