Cone spanner sizes for FH-5700 rear hub?

[Samuel D]

I got my new Spa wheels today and attempted to measure the flats on the cones and lock nuts of the rear hub, in order to buy a pair of cone spanners for adjusting the bearing preload. Looks like they’re 14 mm and 15 mm (at least on the non-drive side). Is that correct?

The Dealer’s Manual for the FH-5700 would presumably have this information, but I wasn’t able to find it on Shimano’s tech-info site. Maybe I’m looking in the wrong place!

Thanks.

IIRC they are 15mm on most shimano 'road' rear hubs with recessed flats like the 5700. But really you should check for yourself. Might I suggest a set of vernier calipers? You can buy plastic ones that are good enough for this kind of thing.

Nothing standard about Shimano any more. Last pair of Shimano road wheels rendered my tacx cone spanners (double ended covered 13,14,15,16 mm ) obsolete as the cones were 17mm.
As Brucey says you need to measure them before investing in some tools.

I already have a high-quality Mitutoyo vernier calliper, but I use it for things that must be kept scrupulously clean. Guess I’ll have to use it on the hub.

Edit: measured. I guessed right! The flat on the cone is 15 mm, while the silver locking nut outboard is 14 mm. Presumably the drive side is the same?

Hopefully useful for some other Google searcher looking for cone spanners for a Shimano 105 FH-5700 freehub.

Indeed, thank you!

Excellent.

Since then, I have acquired a nice pair of 14 mm and 15 mm cone spanners by Park Tool. (Though I made the mistake of first buying the cheapest cone spanners I could find – they deformed on the first job. There must be good, cheap ones out there, but I didn’t get lucky.) The Park Tool ones fit the hub perfectly and are made of sterner stuff.

good cheap ones? Hah... -not so far!

I've used Sugino, Tacx, Campagnolo, Park Tool, and shimano cone spanners.

Any of these is good enough....but my favourite is campagnolo. In addition to the 13/14mm spanners still available, they used to do 15/16mm spanners to fit their Nuovo Tipo hubs and also 17mm ones to fit their triple bearing pedals.

The Park Tool design is OK but flawed IMHO; goodness knows why, but they have added a hole in the spanner too close to where the stresses are highest. In extremis this is where they break. In fairness they need a deal of abuse before this is likely to happen. When they fail they fail by brittle fracture.

Sold my Campag ones - dunna like double ended wrenches. Chucked out my Tacx because I dislike the chrome plating flaking off, but only cosmetic. Now using Park Tool.

Hi,
I have some "Elite" ones, quality is as good as any brand name spanner, silver satin finish.
Only ones I have every owned, abused but still good as new, must have bought them over 20 years ago.
