Re: Campag freehub cassette carrier

In the case of Campag, cassettes started with the introduction of 8 speed. Assuming that's what you have, a newer 9/10/11 freehub body cannot be fitted.

Re: Replacement for HyRd disc brakes - suggestions?

You get a pair of the shorter version actuation arms for your HyRd calipers. Then they work.

Re: Drilling holes in an aluminium frame

The bottom of a seat tube will have the thickest walls of the three main tubes. I f angles are tight though, drilling will be difficult. A right angled converted chuck thingy will be too big, so you will have to use drill bit on a flexible thingy instead. Will make drilling clean/neat holes difficult.

Re: Drilling holes in an aluminium frame

I think the idea would be to only drill in those three locations where bottle cages are usually fitted. Drilling for a third bottle cage on the underside of the down tube would be the least of my worries. But if you have a small frame make sure the front wheel will not contact the tip of any bottle ...

Re: Ishiwata ex triple butted tubing.

Ishiwata EX is 4130 CroMo. Same stuff as Reynolds 525/725.

But unsure if Ishiwata EX is heat treated.

Shimano Style Cassette Lockring Tool

Unless I am mistaken, the Park Tool FR5 has been replaced by the FR5.2. Anyone know the difference? Longer splines?

Thanks.

Any reason not to use Velox fabric rim tape?

Nylon/PVC rim tapes have always been a bit of a frustration for me. Difficult to line up in the case of some rims, and the Mavic tapes in a pair of my wheels are starting to wear around the rim holes despite the tape being rated for HPs. In contrast, I've never had an issue with Velox fabric rim tap...

Re: Shimano and Campag Triples

Just would seem more logical for the manufacturers to offer 'proper' triple RDs to cover all bases. For them not to do this is, I think, compromising safety. They do offer them, just not in the groupsets you're looking at. Although I'm not actually sure what Campag options are available as a curren...

And likewise, I have set up all of my triples to do bib/big.

Re: Are my new rotors defective?

if you move the calipers (by some magic and/or spacers) you may find the pads overspill the OD of the disc instead.. Kind of thinking that would be better than having the pads wear down the spokes of the rotor. A kludge fix is to grind back the friction material on the pads by a small amount at one...

Shimano and Campag Triples

Time was when Shimano did a 'triple length' rear derailleur. And time was when Campag did a 'long cage' RD (89mm) for triples. Campag Athena Triple RD cage now measures only 82mm. Shimano GS cage is also 82mm, and it is what Shimano says is for use in triple systems, eg Ultegra GS works with Ultegra...

Are my new rotors defective?

My disc brake calipers fit straight onto post mounts. No spacers or washers or anything between post mount tab and caliper. Pads line up on brake track perfectly with my old Promax rotors. But this is not the case with my new Aztec (Madison Cycles) stupid rotors. The brake track is a good 2 or 3mm n...

Re: BB30 to GXP

Usually, cranksets with 30mm diameter axles do not fit into traditional/threaded BB shells. No 'proper' BB30 crankset will fit in a trad threaded BB shell, only something like a Rotor or an FSA 386 Evo crankset and which have extra-long 30mm axles will. Are you sure your existing crankest has a 30mm...

Re: Crank / Bottom Bracket Query

The gap is meant to be there on a BB30 crankset. The space is taken up by a wavey washer/spring.
