Hi all, this is my first post. Now, please excuse my stupidity if I'm asking something to which the answer is obvious. I promise I do have a a fairly good understanding of bikes . Here's my question:

I have just got a new and my first road bike. The bike came with 700x23c tyres and the rims are as follows... 'Reparto Corse DRX4000 700CX2-14H F/V'. The inner tubes with the bike are 700x18/23c. I have bought some 700x25c tyres for the bike. Will these existing inner tubes be fine or do I need bigger ones? Basically, are 23c wide inner tubes fine for a 25c tyre?

Thanks

No problem.

Should be just fine. Tubes are very stretchy and work great a decent way bigger than their specified range. Some people even recommend 23c tubes with 25c tires for the size and weight savings.

Ok, thanks. I've put the tubes and the tyres on and all seems to be fine. Looking forward to going out!

Welcome, and enjoy that Bianchi!

I use 18-23's in my 25 tires, no issues.

I learned something new today as well!

Can't wait to go out, weather has been awful though. The last thing I want to do is fall off after 10 meters. Got everything ready though!
