The 75mm Specialized Command post is very short. Pretty good clearance for older frames with interrupted seat tubes.

That'd be 30.9 only? I need 31.6mm.

I'd take a KS without shim over a Command Post with shim every time. The undamped action of the commands is a little scary.

Hmm I thought they did 31.6mm for a little while. But now that I've looked I can't find any reference to it. People must've been using shims. The rebound is quite violent. I wound up dropping the pressure which helped. But it's not on my bike...
But it is a very short post in 75mm. I'm not sure many others would fit in that particular frame.

Has anyone successfully used a Hope pro 3 freewheel on a pro 2 (non-evo) hub?

I'm pretty sure you can put pro 2 non-evo internals in a evo hub, but not the other way round - is that right? I'd be happy not to use the evo stainless steel bearings but I do need to replace the bearings anyway....

Thing is, i'd like to use my old wheels on a new 11 speed cx bike but the non evo freewheel doesn't take 11 spd without modification - but I have a campagnolo freewheel from a pro 3. Google tells me that Sram, Shimano and campy all have the same cog spacing for 11 spd but campy 11 spd cassettes fit on campy 10 spd freewheels.

Can i just put bearings with a larger ID into the freewheel and run it on the old pro 2? Or change the pro 2 hub axle to a evo? Or just give up and put an ultegra cassette in the lathe?

Less than 50% of my bike collection is Specialized. If you only count complete bikes.

Annoying tick on the townbike. Trying to isolate.
occurs when pedalling, in time with each pedal stroke but intermittently, ie, not every single rotation. mostly on the lefthand, but sometimes both sides. i can kinda replicate at will now, seems to be when there's more forward pressure at top of stroke. made me think it was the crank-BB axle interface (squaretaper if i recall correctly), but tightened crank up and didnt stop it.

it's not the ends of my shoelaces, or crank interfering with frame, or anything else i can see.
i have so far:
tightened chainring bolts.
tightened cranks.

only other option would be bottom bracket, am i right?

BB shell / frame movement has caused that for me (when I still had internal BBs).
Fresh grease and tighten can sort it out if the bearings still run smooth.

Front derailleur cable end? I had that once, drove me nuts for ages - felt so stupid when I figured it out. Was only when I was in the big ring from memory.

Doesn't make sens if it happens on both sides of the pedal rotation though...

Id be going for:
Remove and grease chainring bolts and interfaces (not just tighten)
Remove and regrease BB (agree with velo, I've definitely had this on square taper BBs in the past)
Checked your seat post clamp and seat clamp?

oh, sorry, shoudl have mentioned...

single ring at front (Alfine 8spd at rear) - so, no derailleurs. None! thanks Conners

Ah, regrease chainring bolts, good idea.

and yeppo, figured the BB was the next on the list.

Ta fellas.

I can only imagine the sorts of creaks that an assploded Alfine might make... :paranoid:

I had a similar thing and it went away when I removed and greased the pedal threads before refitting.

Dougal - Does your 2015 27.5 Anthem Adv bearing kit also fit the 2016? Also does anyone know if using non-proprietary bearings is a warranty issue for Giant?

Want to steer clear of a certain shop and use my local but my choices are limited. Had my bike built up on a warranty frame and after about 10 rides found a number of issues. Found out it had been put together without lube in the pivots and the headset not pressed in fully.
