powerpod and 650b tires

[tex222]

Hello,
My road bike uses 650b tires that are 41mm wide. My handlebar is a flat moustache style, I assume setting "hoods" as my position is the best I can do?

My mtn bike (fully rigid) is a 29er with 3" front wheel and 2.4" rear. What tire setting should I use for that? I use jones bars so I assume "hoods" is the correct position to put?

thanks
tex

new to powerpod. My wheels are 650b 42mm. 665mm total. What tire sidewall marking should I choose? I suppose 700c x23 is closest. Why not just allow us to enter a value?

You can use this website to get the circumference of your tire:

Your tires are 2098mm circumference. This is within 2 mm of a standard 700 x 23C road tire (2096mm).

So, you can enter 2098 manually in Isaac, or just use the default value of 2096mm.

Thanks for the reply. I don't see where I can enter the circumference in isaac. Looks like it can be set in powerhouse, but I can't get powerhouse to work. I'm just using 700c x 23c for now.

700 x 23c is "off" by only .09%

No worries!
