Frame pump for rSogn seatstay?

[Rory Woods]

Hi all, 

I'm wondering if anyone has found a frame pump that fits using the peg on the NDS seatstay, as seen with the pink (Zefal?) here. 
Measuring my size L, it seems it would need to be just shy of 40cm in length, which doesn't seem available. 

Any leads? 

Thanks!

Rory

Hey Rory, looks like I’m using the Road Masterblaster 4349. I’ve had it there a long time so I have no idea if it’s still available or not, but it’s served me well. 

Cheers,

There are couple of the Topeak Masterblaster frame pumps on Fleabay. 

Here is the link for sizing for those frame pumps.

The smallest size Mike FramePlumper from Rivendell Bicycle Works appears to be just shy of 40cm in length at minimum.  I tried to add 200 of them to my cart and they only allowed 11, so it's in stock with some margin of safety.

When I had my rSogn that's what I used as well. I sold it with the bike. They are no longer in production but are around in circulation, eBay, used etc.

@Rory,

What decision did you arrive at with a frame pump to fit your bicycle  ?

Would a modified lyzene road drive work here?

The modified Lezyne road drive hack generally requires double pump pegs and rSogn has 1.
