XTR M952 mountingbolt

[Martin]

Who knows what kind of bolt is the mountingbolt on a XTR M952 stiset?

Does anyone has a picture?
Or is it just a m6x20 mm?

Would be a great help for me.

Cheers,
Martin

Solo Sti or integrated with the brake levers? mounting Sti to the bars or sti unit to the lever assembly?

I have the solo in a box somewhere if that is what you need.

Enjoy!!

I'm pretty sure it's an M8 fine thread bolt, the same as on the M950 brake lever.

the ST-M952 pdf at the Paul Lange site shows an M6 bolt, but I think that's a typo.

Martin has not confirmed which unit we're talking about. In the for sale section is the picture below, and FWIW I don't think the M6 is a typo.

Well, he did say "STI set" (i.e. combined brake/shift lever set) not "shift lever" or "Rapidfire trigger set" etc. Taking that at face value, the only obvious "mounting bolt" (singular) is the large one that attaches the unit to the handlebar. Still, he'll know whether or not my reply was any use to him. Maybe it was, maybe it wasn't.

In the for sale section is the picture below

Those Rapidfire units use a standard M6 mounting bolt, as shown in the Shimano tech documents.

and FWIW I don't think the M6 is a typo.

Well, you might be right. I don't own any 952 STI units any more, but my memory is that they used the same M8 fine thread clamp bolt as the M950 brake lever. Certainly, the 950 and 951 units do, as does the 960. Still, without one here to measure I can't confirm, but Martin will be able to figure out which is correct, I'm sure. If an M6 is obviously too small, it must be M8.

I dug out my Sti (without the brake levers) it is a bulbous bolt head for a 5mm hex key and the diameter of the stud is 6mm max, that's an M6. Just like the one in the picture.

If I blow up the drawing in the klink posted for the clamp WITH brake lever to a larger size it is quite obviously a totally different bolt with a thin rim rather than a bulbous head. If that fits a 5 or even 6mm hex key inside the stud it must be a bigger diameter indeed.

so apologies, , I should have looked first before commenting, my personal experience is with the solo sti unit only. I just did not expect the combination of the big S and typo's ....

Enjoy!!

In that case, M8 x 1mm. It's the same thread as a standard chainring bolt. Some granny ring bolts are just about long enough to work as replacements for the pukka XTR item.

Feast your eyes!

I dug out my Sti (without the brake levers)

You see, to a pedant like me, there are brake levers with BL part numbers, shift levers with SL part numbers, and integrated (STI - Shimano Total Integration) levers with ST part numbers. If it isn't integrated, it isn't STI.
