Frame Pump For Thorn Mercury 610L
08 Sep 2016
Can you recommend a pump to fit this frame
Presta valve. Do not like Mini pumps.

As there are no pump pegs on your bike you'll need to go for a pump that can work without pegs like this Topeak pump. You'll need the XL size to fit the top tube on your bike.

Best Frame Pump For Thorn Discovery Tandem?
07 Mar 2016
The bike just has one pump peg, what's the pump you'd recommend ? It's about 50 cm to frame angle. My mini pump struggles to get over 50 psi. Graham
SJS Customer Service:

The frame pump we recommend is the Zefal HPX (SJSC part number 37684) these are designed to fit to a single peg and are what we have fitted to our bikes for a large number of years.

Topeak Road Masterblaster™ Still Confused By Sizing!
13 Nov 2015
Looking at the Topeak, to put under my top tube (49cm gap), am I correct in going for the large (47 to 52.5cm)?
SJS Customer Service:

Unfortunately for some reason Topeak bases its sizing on the frames full size rather than any of the lengths relevant to where you are going to fit a pump. You are correct though for your frame you would need the large size.

Which Frame Pumps Will Fit A 57Cm Frame (50 Cm Opening)?
09 Mar 2015
Sorry but I'm totally confused since some descrptions (Zefal) refer to the pump length (ok got that) others refer to frame size (understand that but then the topeak shows illustrations highlighting the top tube measurement which is different to those given in the size list and others are ambiguous. Iin the case of the Silca I assume its frame size but for a sloping tube compact. Is it a ploy to make us all buy the Park Tool?

I think Topeak Large/Zefal size 3 and of course Park Tool are my options but I'd like to be sure since returns are a pain. I know its a tiny thing and you have loads more to do and information comes from manufacturers but using a consistent measurement ie pump actual size would be a real help . .. .... help!!
SJS Customer Service:

Any of the 3 options you have suggested would be suitable. The Silca, Zefal and Park Tool all refer to opening size (actual pump length) where as the Topeak is referring to full frame size and the pictures showing the top tube measurements are the actual size of each size of pump. I will update the sizes on the Topeak so all the pumps show the actual length of the pumps in the sizing to help choose the correct size.
