Which is the 15mm? I keep a craftsman heavyweight in my bag. It doesn't weigh that much.

Your not carrying enough "stuff" if your worried about the weight of your wrench. Heck, my lunch is 3 pounds.

Well my Hazet 15 mm combination wrench also has the open end, is 218 mm long (8.6 inches) and is only 99 grams. It is much better quality than the craftsman. I find for my SRAM dual drive hubs that the extra torque a full size wrench affords really helps. In addition you get the open end which works for some pedals (works for mine, some need a narrower head). The box is also offset which is a big plus. Won't fit in a small seat bag though. If you want to save weight and have it fit in your bag you could cut it to a 5.5 inch version that would fit in you tool bag and save about 40 grams, but you would lose the open end and the leverage. They cost about $20.

I don't know about its weight, but you can find these pretty easily in Europe, or on ebay if you search for "dumbell spanner:"

It's not very heavy, fits the hand well (plenty of torque for axle nuts) and in addition to your 15 mm wrench you also have a 16 mm, 14mm, 13mm, 12 mm, 11mm, 10mm, 9mm, 8mm, 7mm, and 6 mm wrench all in one.

Gee, and it's only $103.58!

That's just the price you pay for hypoallergenic!

Seems to me the Park Tool and the Campy tool have a certain cache that goes beyond weight.

You can get a dumbell spanner from Rivendell for $8. http://www.rivbike.com/products/show...ll-tool/19-063

That's a good deal. I've presently got three of 'em that I got cheaper on ebay, but if I didn't, I'd go for $8.

I just carry a regular socket wrench with 15 mm socket that you'd find in any hardware store. I guess there's a weight penalty, but those lightweight wrenches all look like a PITA to use. If they're too short, it's harder to get enough leverage. If they're just stamped out of a sheet of metal, then it's going to hurt your hand to apply a good amount of force. For me, the extra weight is worth the convenience.

Here is what I carry:

I have a Kobalt (Lowe's housebrand?) stubby combo wrench. I got a whole set for $20 and I keep the 15mm in my saddlebag.

I have one of these. Nice quality but it's quite heavy.

How tough are these? A friend of mine had one and he said he ruined his quickly, and he's a contractor. I've always liked the idea of them though, especially for my old bikes.

Another vote for the Campagnolo peanut butter wrench. Word has it that Campy discontinued production, but they are available from time to time on eBay. A little pricy, though at about $30. It's well worth the style points.

I had one of these for a while (from my local hardware store, not Rivendell), and eventually the 15mm end of it snapped off. Perhaps there are better-made versions out there, though.

convenience is one thing, but to be carrying something like this around daily seems ridiculous.

+1, I ended up with the Task Force stubby 15mm from a Lowe's set and have the others in my tool box. My problem is that anything longer than 5 inches will not fit in my saddle bag, and I prefer to keep all tools and stuff in there so I don't forget them. That PDW 3wrencho looks pretty slick though it costs the same as a whole set of stubby wrenches.

I sent an e-mail to Quality Safety Tools asking how much the 15mm Titanium Dual wrench weighed. They said it was approximately 70 grams. I looked over their website and they also make titanium hex wrenches, both regular and ball-end. These look interesting since most of the wrench is round, only the ends are hex shaped.

That's exactly what happened with my friend's dumbell wrench. He didn't get it from Riv, but I don't know how many different manufacturers there are for that wrench. In any event, if anyone can comment on the Riv dumbell wrench, that'd be great. Also, I'll +1 the 3wrencho. I have one and it's sturdy, light, and about 4.5 inches long.

Been doing ok with this set up so far. I moved the wrench over so you can
read that I'm packing six inches of drop forged heavy duty steel.

Nice chop job! I think the best balance between lightness and toughness would be to make this wrench, then drill and file the polished "Craftsman" bar part out of it. That might take what, about 1/4 - 1/3 of the weight out of it? Tinkering with stuff like this never gets boring for me in case you guys can't tell :D That shouldn't weaken it too much, looks like there's enough meat between the Craftsman bar and the edge to keep it strong.

light (86g), strong, expensive ($33 at the link below though S&S says it should only be around $20:

I like my Surly Jethro Tule.

Not particularly cheap ($20-24) or lightweight, but it is nice and compact while still giving a real nice hand hold for good force due to that spoon-like handle.

Haven't carried this around since the early 80's
