Internal hub (Alfine/Nexus) and carrying 15 mm wrench

Whereas the Alpine/Nexus internal hub has a 15 mm NUT instead of a quick release.



Does this NUT obligate the commuter to carry a 15 mm wrench as part of the tire repair kit?

If so, what is the necessary length to provide sufficient torque? Does this length preclude carriage in a typical saddle bag? If so, how is the wrench carried? Attached to the frame as is a pump?

What is the recommendation for a wrench robust and long enough to effect repair, but the least burdensome in terms of weight and size?

For example, the Park Tool PW-5 15mm Pedal Wrench, which is 29 cm in length. Would a lesser, shorter wrench still be sufficient?

sure you can use a shorter wrench, just make sure the handle is comfortable. Regular box end or open end wrenches will probably be longer than you want but 6" crescent works. If you're really trendy search around for a Campagnolo wrench.

I use a dumbell style wrench (cast bronze) abut 12cm long.
Im sure I could find a lighter-weight version.
You can saw down a std wrench to a stubbie. I think ring style is preferable to crescent, it allows you to apply some foot power if required.
Note that the tightness required of this nut depends on the style of dropouts.
Vertical dropouts require much tightening since the axle cannot move forward. Horizontal dropouts may need a longer wrench to get them tight.

Whenever I've had a puncture, even on a derailleur bike, I don't bother removing the wheel. Just lay the bike on its side and pull the tube out. You can usually fix it without removing it from the bike. I just carry an adjustable wrench in my toolkit rather than individual sizes. It might not be perfect but for a running repair it works ok.

I hadn't thought about this as an alternative, I'll make sure to have a good patch kit and pump and give this a try first, even if I do have a wrench.

There are plenty of shorter wrenches out there that would easily suffice. I carry the Craftsman 15mm stubby. http://www.sears.com/shc/s/p_10153_1...u=00944117000P

Tons of "designer" wrenches have been created in the last few years for the fixed gear crowed since most those wheelsets use 15mm bolts to attach the wheelset to the frame. Search the forums, specifically the FGSS sub forum for many more options.

Surly and PDW make great compact wrenches. The Surly has a bottle opener; the PDW tool doubles as a tire lever. They are short, but you can always stand on them for extra oomph.

The alternative is to keep a patch kit and fix the tube while the tire is still partly mounted on the bike. (assuming you pulling the wheel for that purpose.)

Nice, looks like just the thing. I wonder how long it is, and whether it will fit in my saddle bag?

Campagnolo Peanut Butter Wrench 15mm for Axle and Crank Bolts



(Speaking of trendy, I guess fixie riders have the same wrench needs. Over at the Fixie Sub-Forum, there is a 5 page thread on the same topic).

There is this for $24...

Ti opener with 15mm wrench



Solid 6/4 Titanium Bottle Opener with 15mm Wrench Approximately 4 1/2 inches long Great for cyclists Light and easy to carry Bottle opener on one end and 15mm wrench on the other end

...which is made of titanium, and doubles as a bottle opener. This looks good, but over at the Fixie forum, it was found wanting.

Okay, this looks like it would work, and fit in the saddle bag. As a commuter, however, I have less occassion for use of the bottle opener than is apparently the case with fixie riders.

Surly Jethro Tule


Our Jethro Tule pocket tool combines an offset box wrench on one end with a bottle opener on the other. The double-sided 15mm box wrench works with most nutted hubs on the market, and it fits nicely inside recessed dropouts, including those found many of our frames (the 1x1, Steamroller, Karate Monkey, and Pugsley). The smooth, spoon-shaped handle provides ergonomic pleasure for your palm under the most rigorous wheel-removing operations, and it opens a cool refreshing bottle of whatchoogot after the ride. The Jethro Tule is “Thick as a Brick”, crafted from stainless steel and then polished. It works like it’s supposed to and feels good in your pocket.


A tire lever too is perhaps more helpful than a bottle opener.



PDW 3wrencho™ (coated)

The 3wrencho™ (coated) is your best buddy when you have a flat. Unlike your other friends the 3wrencho™ is made of heat-treated steel, removes 15mm axle nuts and can pry tires off of rims. Don't worry, its glass-filled nylon coating is gentle on your pristine rims. Feel free to step on 3wrencho™ for added leverage when loosening axle nuts.

Other uses: spread jelly, stir a drink or open a letter.

This is a lot harder than it sounds if you have a skinny tire on your bike like I do. First you have to figure out where the puncture is, which sometimes isn't possible without removing the tire, and isn't possible most of the time if you carry CO2 rather than a pump (not that you would :-)). Second, it's a real pita to try to get the tire out without taking the tube off. It's not necessarily impossible, but the last time I tried it I couldn't get it to work, the skinny tire would not give me enough room to get the tube out. Maybe there's a trick to it.

I have an alfine hub - I think I carry one of those surly tools, and an adjustable wrench in my bike bag (can't remember - I think you need a wrench on each side, I'm really not sure though).

I would look for a 6" open/closed end wrench. The normal size is 7 1/2". A crescent will round the nut in no time.
This way it doubles for a pedal, cone and maybe seat post wrench.

Random thought: How about a nice pair of 26tpi x 3/8 wingnuts?

Being closed and all, it looks like a bolt. I haven't had to take it apart to see what's in there.

Anyway, I corrected the offending OP.

You'd have been useful General McAuliffe at Bagstone.

The wing NUTS would need a long wingspan to have sufficient leverage.

I just built a bike with the new 11 speed Shimano Alfine hub. It calls for about 40 ft. lbs on the axle nuts -- way too much for wing nuts unless you turned them with a sledge hammer.

BTW, the 11 speed Alfine KICKS ASS!!

I carry an S-K shorty 15 mm wrench, no problem.
My commuter tool kit is a Park MT-1 multi tool, the 15 mm wrench, a valve stem wrench and a Quick Stick tire tool. Also carry a spare tube, some patches, and a pump. This set up has taken care of 110% of my commuting needs for the past couple of years.

Jethro Tule, FTW. Small, excellent fit, angled head so you don't slam your hand on the chainstay when the nut finally gives way, wide enough to put a palm on it for leverage (or a foot if things are really stuck), bottle opener for my ginger ales, key ring loop to attach it someplace and not lose it.

Carried a 6" adjustable wrench for years when riding an old Raleigh 3 speed. Someone gave the Jethro Tull for Christmas, it is in the saddle bag of my city bike.

I carry a crescent wrench because of the serious shortage of descent wrenches in bike repair kits. Yes, a crescent wrench can round off your nuts. Adjust it properly and treat it with respect and it will get you out of a jam. At home, use a real set of wrenches. At least a crescent wrench grabs the flats on the nut. Vice grips want to grab the corners. Same with 12-point box wrenches or sockets.

As for a bottle opener, it seems the only way to sell an item to the fixie market is to somehow incorporate a bottle opener in it. I'm guessing they've never heard of a twist-off...

I have a Craftsman Robo-Grip set of pliers that I try to remember to carry with me. My hub uses a different sized bolt on each side due to the attachment of the hub shifter, so something adjustable makes sense. But my commute is only 5-8 miles with a bus that'll take me home in a pinch, so if I don't have my Robo-Grips on hand, I don't sweat it unless I'm taking a longer ride. If I'm really planning ahead, I also carry a Craftsman Pocket Socket (adjustable, close-ended wrench), although that's overkill anymore as it's only usable on one of the two nuts. But what has really made the difference for me is my Schwalbe Marathon Plus tires. It's so rare that I have to remove my tire anymore that I have gotten very lazy about carrying tools to do it, but my most consistent tool is the Robo-Grips. They seem to come in handy in multiple situations in addition to wheel removal.

I bought the Paragon Machine Works wrench and they sent me a key-ring PMW bottle opener for free. I looked at the Park Tool and PDW and they were both quite heavy. If only the PMW could have thought of some better uses for those extra holes...

So you bought the Paragon 15 mm Wrench Bottle Opener, Titanium, which is also a bottle opener...



...and they sent you in addition a key ring bottle opener?




But, does the Paragon 15 mm wrench work? On the fixie forum a user said that the titanium stripped when the torque was applied.

I have the PDW 3wrencho. I've had to pull it out a few times while on the road over the last year, year and a half. Works fine and offers a nice, relatively long flat surface for leverage.
