unfortunatly not. i secure mine on the down tube. fits great.

My opinion is that the L needs to go on the frame, but that the M could be carried in a pocket. The saddle bag isn't likely to work for carrying any size of this pump unless you're using an enormous satchel.

I would say it is around 24cm long, not sure if that quite allows for pocket or saddle bag storage. Definitely in a small backpack or similar though.

The large certainly isnt. However if you buy a pump that fits in a saddle bag the not sure how useful it would be. You might want to try a CO2 pump as these are shorter.

Medium is 23.5cm

the one attached to my bike frame is 295mm. I carry it in a messenger bag sometimes when I'm on a different bike.

Lezyne say

Grams 90 g medium / 106 g large
Diameter 19.5mm
Length 216mm (medium) / 283mm (large)

Ummm, my bike is elsewhere so can't give you exact length but it is too long to go in a saddle bag. It would go in a pocket.

The bracket it comes with holds it very neatly in alongside your water bottle cage (and tucked under the water bottle when it is in place), it really doesn't get in the way there.

The main part of the valve can be smooth (like a vittoria ultralight) you just need the little bit right at the top to have a thread, which I'm sure all valves do

Yes, it does. Presta only - you get much better performance by screwing the extension tube onto the valve first, and then screwing the pump onto the tube.

yes as it has a screw on adapter

yes, it has a threaded rubber hose to attach it to the valve

Road Drive pumps are for Presta valves only

Yes, it does need threaded valves. In fact, that is its primary advantage, as you won't get those awful valve tear-outs you can have with fixed-head rubber-grip pumps.

Barrel and body is silver. There are black rubber caps at either end, and a black rubber seal to keep the handle fixed when not is use shows up as a black band around the pump.

The one I got was completely silver, other than the black rubber bits. Looks smooth.

totally silver, looks great

looks just like this http://www.wiggle.co.uk/p/cycle/7/Lezyne_Road_Drive_Mini_Pump/5360040898/

The rubber seals and end caps are black. Otherwise, yes.

I bought a large and it is 295mm long and about 24mm wide at the handle. Medium is a little smaller.

295mm x c. 19mm. It does fit nicely on the bottle cage braze-on attachment too if that helps

Roughly 8 inches in length

according to the Lezyne web site the sizes are as follows:-

Grams 90 g medium / 106 g large
Diameter 19.5mm
Length 216mm (medium) / 283mm (large)

This is a US product and on the home web-site it does offer spare mountings, but don't know how easy they would be to source in the UK. I would be afraid of forgetting to change the pump over so just bought one for each bike.

Yes you can, I bought one just the other day. They're on Wiggle, listed as "Lezyne Alloy Bracket Mount for Road Drive Pumps", at £8.99.

Yes, you can. I've done precisely this.

Yes.

Mine came with a black bracket; so the answer is yes.

fwiw My Road Drive L in black that I got today, came with a black bracket.

it appears only the white version comes with a black bracket unless you go for a Carbon Road Drive. Lezyne's website only shows plain alloy brackets as spares

if by powerful you mean does it pump more air then yes.

according to Lezyne both go to 11 bar/160 psi. I guess the smaller one will take more strokes to get there.

The weights of all the pumps are on the website. The weight will depend on which size you buy but the large is about 106g

According to Lezyne...

Grams 90 g medium / 106 g large
Diameter 19.5mm
Length 216mm (medium) / 283mm (large)

295mm long including the rubber caps.

235 mm

Grams 90 g medium / 106 g large
Diameter 19.5mm
Length 216mm (medium) / 283mm (large)
