Seatclamp size on 2006 Spesh Hardrock Disc

Posts: 84
Hi. I'm looking to replace the seatclamp on a 2006 Specialized Hardrock Disc. I've removed it and measured and also the size is printed on the inside as 36.
36 currently seems like a very non-standard size on any of the sites I have looked at. I was hoping to replace with a Da Bomb seatclamp but they don't have that size, only 34.9

or a Hope one at 36.4:

Neither of these is bang on. Has anyone any experience of replacing the 06 Hardrock clamp and what would actually fit. I think the seatpost is pretty standard, just the seatclamp seems hard to come by. Any help welcome. cheers!

36 would be unusual - sure it doesn't say 35, which would be 34.9?
Or measure again

Weird it says 36 on the clamp as in my experience Specialized bikes use 34.9mm clamp... eg my old Demo and SX Trail did, as does the 13 Enduro Evo.
You can also look on the front mech, as it's the same diameter tube
Pretty sure 34.9 is what you're after, but you could always order two and send one back as CRC are great for returns.Current:

yep cheers. Almost certain it said 36 but could just be scored and say 35, in which case 34.9 should be a correct fit then? I thought it was bit odd I couldn't find any 36mm since it is a really common bike.2006 Specialized Hardrock Disc (rebuilt)

Just to confirm - clamp size on both my 2004 and 2007 models is 34.9mm so would be very surprised if 2006 is any different0

cool. Will order and post a pic of this bike when I FINALLY finish it. Going for a full rebuild in orange powder coat and metallic blue trim, new wheels/drivetrain/forks...the works. I love this bike. It may be entry-level but something I love about that fat tube and overall feel of riding the bike.2006 Specialized Hardrock Disc (rebuilt)

Actually, this doesn't work for the hardrock - the seat tube tapers sharply a few inches above the BB, so the mech actually needs shims to size it down a notch. Not sure why they chose to do it this way - it's damned annoying as it means you can only fit a low-band mech (high bands naturally fall at the point where the tube tapers).0 -
That's always been the great thing about Specialized, their frames can last years.
Sounds like it will be a cracking bike once built so be sure to post it up in the Your Bike section once complete (or even whilst building!)Current:

Yep I noticed this about the seat tube tapering like that. Bit unusual but as long as I can get it fitted shouldn't be a hassle. Fitting it with mostly Deore drivetrain, with Spank stem, truativ bars, ragley seatpost & seat, ODI grips and nukeproof pedals. It will end up being the sort of bike I would just be scared to lock up anywhere...lol2006 Specialized Hardrock Disc (rebuilt)

Like I say, just make sure you have/get a low-band mech, as high-band ones simply won't fit.
I had picked out this one hoping it would fit ok: http://www.chainreactioncycles.com/shim ... -prod692982006 Specialized Hardrock Disc (rebuilt)

No idea if jimothy is right, but this is the bottom clamp/top swing if he is.

Sorry, but I'm 99% sure that one won't fit, if you've already ordered it then you can always try it to make sure, though. Otherwise order the one cooldad links to, as I know that one will definitely fit.0 -
cheers. Haven't ordered yet so thanks for the advice. Basically I'm not ordering any of the expensive components (wheels/forks) or drivetrain stuff until the bike is powder coated. Then I will know if it's a "go" or not.2006 Specialized Hardrock Disc (rebuilt)

cheers for the parts info. Here's the spec as it stands now. I started this back in July I think and posted about it on the forum back then but various things happened and only getting round to it now. Stuff I have already bought include: ODI SDG grips, Nukeproof Neutron flat pedals, Ragley Cheeky saddle. I'm re-using Avid Juicy 3.5s which I put on the bike years ago but everything else will be brand new. Keeping the old rear mech hangar and the cable pull thing (not sure what it is called) under the BB.
You will see 2 x cranksets in here as I'm torn over the double vs triple. I would be keen to know if the headset will fit. I think the one on the bike is a Cane Creek conventional threadless and I hope the Octane One I have specced below is conventional threadless also. Wheelsets & forks have been a bit of a trial since 9mmQR and non-tapered forks seem harder to get and are looking like old standards now.

Yes, as far as I can see there should be no problem there.Wheelsets & forks have been a bit of a trial since 9mmQR and non-tapered forks seem harder to get and are looking like old standards now.
You will need a straight (1 1/8") steerer, but you don't need to stick to 9mm axles - there's no reason you can't use a 15mm or 20mm axle as long as the wheel and fork you choose both use the same standard.0 -

I'm afraid I couldn't manage the 1x10 as the bike will be used for some steep climbs and also used to get me to/from some local trails on roads. As long as the bike ends up lighter than it was before (13.7kg) I will be happy!I would be keen to know if the headset will fit.

Grand. Hoped this bit was correct.Wheelsets & forks have been a bit of a trial since 9mmQR and non-tapered forks seem harder to get and are looking like old standards now.

This did cause me some confusion when speccing forks & wheels so I know now the wheel/forks standard match. I was unsure about what I can run on the rear axle as the width on frame is 135mm but I think that's pretty standard. Do some wheelsets come with 15mm or 20mm adapters? I've heard that some Mavic sets do. Cheers2006 Specialized Hardrock Disc (rebuilt)

Generally wheelsets these days are available in a variety of axle options, and many do have swappable adapters that can be used to change them to suit other standards (although I don't think many come with those included - they're generally aftermarket purchases, as it's assumed you buy the version you need in the first instance).
The rear wheel axle is dictated by the frame, and you will indeed need 135mmx10mm. However, that doesn't limit your front wheel options at all - decide which standard you want to use (ie which wheellset you want), then buy a fork which can accept that standard.
You're right that 9mm QR on the front is becoming a less standard "standard" these days - 15mm through-axles probably represent the best option for your build, so you could maybe look for wheelsets that give 10mm QR rear, 15mm front, as an option, and then buy 15mm forks to match.0 -
thanks ! Very useful info. One final question on the front mech. Would this slightly cheaper one also fit ok? I'm trying to spec the bike for 10 speed either double or triple. Seems to be top swing and allow low pull:

yep - that should work. Choose the 31.8mm version to get the right size shims.0
