anybody heard of deore lx 660 series?

Hi,

I'm looking for some hubs to build up. I found these on ebay and they seem a decent deal, but can't seem to find any documentation on them (ie dimensions for spoke ordering or anything else) by googling them. Are they legit Deore LX hubs or some counterfit? I know some people are nervous about buying from asia, but I have had good experience getting microshift parts from across the pond and they have decent feedback.

Shimano's Tech Documents don't list any Deore LX hubs by those particular model numbers. However, most of Shimano's hubs have very similar hub flange diameters, spoke hole circles and flange spacing so you could probably use the data for any of them. However, I recommend you do one of the following:
1. Buy hubs where you can be sure what you are getting.
or
2. Take your chances and buy these but wait until you actually have the hubs and take the necessary measurements yourself.

Yeah, will probably just go with the tiagra hubs I was planning on, but thought these might be a good deal if they were a legit part and might be more secure. If I was going to spread the frame from 126mm anyway, thought I might go to 135 as well as 130 and dish less for a sturdier hub, but if they're questionable, I'll just go with what I know.

They appear to belong to the Shimano Deore LX "trekking" group: http://cycle.shimano-eu.com/publish/.../deore_lx.html
Not seen very often in the U.S. That would follow since the Ebay seller is in Hong Kong.

As Hilly said- Shimano has kept their spoke hole diameter and spacing consistent for the last couple decades. At least, I've never had a problem plugging random Shimano hubs into spoke calculators.

The hubs show up on shimano's web site, but they don't show the dimensions in their tech documents.

there's no way shimano would change their hub dimensions from the usual 38mm front and 45mm rear for their low and middle range hubs. That would require retooling.

It's also possible to use a different spacer on the rear and lop off the excess axle to get it down to 130mm OLD.

What the seller has is a pair of LX treking hubs, the seller has got the model number somewhat incorrect, the M660 model number relate to the SLX groupset, not LX, the seller should be listing them as T660 http://techdocs.shimano.com/media/te...9830648102.pdf and the rear http://techdocs.shimano.com/media/te...9830648098.pdf

I looked at Shimano's web site under the OP's exact model number and none of Shimano's tech documents corresponded. There were lots of "LX" hubs but not those exact ones.

Here's the group, sold in europe as "trekking". Just a step down from XT. Good robust group slightly heavier than XT I believe.
http://www.shimano-nordic.com/publis.../deore_lx.html

all the components have 66x designation

edit: this is from the shimano swedish site, but most of the info is in english.

framnav = front hub
baknav = rear hub

yeah, if you look them up under t660, they're present on the shimano site for pretty much every continent other than north america. I suppose T-M conversion could just be a mis-translation of chinese characters.

Currently, rear spacing is at ~120 mm (odd because it originally came as a 6 speed in '81, so I would have expected it to be 126 mm). So whatever hub I put in there, I'll need to cold set it. It's looking like the LX would need 140 mm spacing (based on the rear axle being 148 mm and the front being 108 mm), so I wonder if I should just spread it to 130 mm and get the tiagra I was planning or if it's worth it to spread it to 140 mm (would that damage the strength of the frame to spread it that much to get these potentially stronger hubs. On the other hand, the extra spread might shorten the space up top and I was hoping to have room to put on 32-38 mm tires and fenders.

It was originally a "touring" mixte, so I'd expect to have room for 38 mm tires and fenders with no spread as it was a frame for 27" tires (also the seller who I've had mixed communications with said there was room for fenders as it was), but I don't know how much room I'd have if I spread it all the way.

I guess the question is, are LX hubs that much (or any) better than tiagra? And is there any effect to extra spreading (or extra risk to the frame)? The bike is going for a somewhat heavier rider, so strength is a consideration. Though on the other hand, all the lx hubs I've seen online (and I've seen a couple now), are 32h and I can get a set of tiagra 36h hubs for the same price. Don't know which would make stronger, better wheels.

for your spacing question, the LX T660 rear will be 135mm, the Tiagra (current version 4600) will be 130mm, if your current frame has 126mm spacing, using the Tiagra would require the stays to be bent less.

For quality, the LX are the same level as 105, Tiagra is the same as Deore, 1 step down from the LX range, will you notice in a rear hub, probably not, would be more interested in the spacing.

^^ this is correct

If you're thinking about cold setting to fit a 135mm hub, there's no point in going wider than 132.5mm. With that spacing you can fit both road (130mm) and MTB (135mm) hubs.

I believe LHT (and Novara Randonee?) have (or have had) 132.5mm spacing to enable this...

Not quite sure about your measurements. The front spacing would most likely be 100mm.

I have a Miyata 100, also originally a 27" sport touring bike from the mid eighties. Up to 32mm tires with 42mm fenders work well (excluding Schwalbe Marathon Pluses which are too fat to fit under the fenders). SKS Bluemels come in 42mm.

Going from 126mm spread to 132.5mm is just 3.25mm on each side. Would this really affect the space up top significantly?

I don't know, I just saw that the specs said this one had a front axle width of 108 mm, so I figured that meant the drop out width was 4 mm each. The specs for the freehub had axle of 146 mm (first time I read it I thought it said 148) so I just thought that I'd subtract the same amount again and came to 140. But if the rear dropouts are thicker, the 135 makes sense. Yeah, going to 132.5 so I could go either way makes sense. Can you spread them that precisely with Sheldon Brown's method?

http://www.shimano-nordic.com/media/...9830648098.pdf
http://www.shimano-nordic.com/media/...9830648102.pdf

I did write the seller and asked if they came in the original box and came with dimension documentation (probably it'd just amount to what I linked to). The guy wrote back and said he'd have someone in the warehouse check and get back to me. I don't know why I'm obsessing over a LX hubset when tiagra is a perfectly decent option, but I like the idea of being a bit sturdier (and a member just sold me an old setup of LS shifters/deraillers and I bought a LX crankset on the bay, so a more or less complete group sounds cool).

Don't go after the axle length. It's the space between the dropouts that matters.
Front hubs require 100mm spacing between the dropouts, Rear hubs 130mm (Road) or 135mm (MTB).
Here's a good read: http://sheldonbrown.com/frame-spacing.html

Yeah, I know that you typically need that much space, but had almost bought a different wheelset recently before seeing they said it was spaced to 140 mm, so I knew that was a potential size for some wheels and then tried to figure out the spacing those hubs would use by subtracting dropout width from the axle size to get spacing between the dropouts.

Turns out not to matter as I contacted the seller offering these and even though the pictures are showing silver hubs, they apparently only have black ones left and I'm planning to build up a silver wheelset (older black frame with chrome fork ends and it will have silver most everything else so as not to be overwhelming with the black). So I guess it's back to the tiagra hubs and none of this mattered. Glad I asked the seller before they shipped me the wrong color all the way from Hong Kong with no returns.
