Campag Rear Mech Torx

Coach H

Hi all,

Despite the on-line and paper instructions for Campag rear mechs saying that the fixing bolt is a 5mm hex my new Centaur rear mech quite clearly has a torx bolt. (This Campag trend for Torx fittings is getting a bit silly now, they will even be doing chainring bolts in Torx soon )

Does anyone know what size this is please, otherwise I will have to guess or buy a set.

Thanks

According to these instructions it's a T25

It's the same you need for the Ergos, so no big deal... although I have always used a T 20 for the Ergos and it works just fine as well :shock:

Thanks Ugo. My obvious mistake was looking at the 10s instructions for my...........well, my 10s mech.

Campagnolo claims the 2011 onwards derailleurs (including Veloce and Centaur) have the 11 speed geometry, whatever that means, so maybe they've been fitted with the 11 speed T25 bolt. Campagnolo claims a lot of bxllshxt these days... I look forward to the day when they actually come out with something vaguely innovative.. the 2012 range has nothing to offer over the previous 2011 range, which had only downgrades to offer over the 2010... not sure what designers are doing in Vicenza!

The reason for the Torx head is because they are using aluminium fasteners - if they were left as Allen-key then there'd be no-end of ball-aching due to people rounding the heads. This isn't just Campagnolo but a general industry trend e.g. a lot of chainsets have been Torx for a few years e.g. SRAM/Truvativ and FSA.

Oh great.. I wish they stopped using Al alloy for bolts and nuts... it's crap and the weigh saving does not counterbalance the fact that they're crap.

Just changed rings on an FSA chainset with alloy bolts, had to replace two of them with steel ones as they fell apart (one whilst unscrewing, the other one whilst tightening)... now tell me again, how much weight do I save by having 5 alloy bolts instead of steel ones? 5 grams?
