Any question answered...

Felt my freewheel slip a couple of times about 50 degrees where it just didn't engage randomly and then decided to bite. Seemed to then suddenly be fine again for a couple of hours, should I be worried about it?

should I be worried about it?

Only if you're worried about it suddenly being a freewheel in both directions in the middle of a commute and leaving you stranded.

Is it easily serviceable? It's usually just a sticky mess inside causing the pawls to get stuck, and needs cleaning and regreasing. Or just replacing.

when did tange sekei go from making decent quality steel headsets to ones made from what appears to be brie
i have a feeling the one i just bought isn't going to last a long time

Anyone help me ID this freehub? I am sure its campag, but my 9spd stuff doesn't fit, the freehub is slightly too big. It's got 8 splines and one slightly fatter than the others. 8spd? Which generation? @retrodicorsa??? Cheers

This is an 8-speed ExaDrive sprocket:

I'm not seeing the wide spline on your rotor, but ExaDrive 8-speed cassettes fit on the earlier rotors with equal width splines anyway.

Not sure, it's a shimano one. It's only been on the bike a few weeks.

@Olly398 - Does indeed look like later 8spd. Not many options other than to change the wheel(s) or everything else unfortunately. In some cases you can re-space cassettes with the appropriate spacers but 9spd spacers won't fit the slightly larger diameter 8spd freehub.

Thanks @retrodicorsa @mdcc_tester @Scilly.Suffolk, looks like 8 spd exadrive to me. I want to sell them actually but didn't know what to advertise them as!

I've decided to get a heart rate monitor. Is there a nice and not pricey ant+ option?

This one has been very reliable for me.

Need a bigger messenger style bag pronto, the Bigtop mini messenger doesn't cut the mustard for a full set of clothes, shoes and work accoutrements.

Where in central London can I pick one up tomorrow? Resorting to using my massive rucksack for the ride in.

What torque is recommended for the faceplate bolts of a Thomson X2?

I had similar from a shimano, probably one of the the pawls sticking, but bad after such a short time.

I'd recommend spending more than a tenner on a free wheel, that way if it's faulty it's worth actually sending it back! :)

Buying old stock I guess. I'll take some time to service it a bit better after I'm back from my holiday.

I think 5nm, though it may also depend on what your bars are made of and their manufacturers spec.

Thanks.

Bars are aluminium. Zipp SL70.

I've got a feeling the stem faceplate is the weakest link :-/

Put some alu cranks and a Thomson seat post in the dishwasher last night.... Wont be doing that again.

Anyone know the best way to bring back a nice sparkle to aluminium? Went out and bought some 1500 and 2000 grit wet n dry but want to check here first...

One more - a hypothetical - would a builder find it easy to make a new steel fork for a frame with an over-sized head tube and make it look good? I am thinking of getting a rando style fork for the bike with lots of eyelets for the usual racks/mudguards. The 'low trail' fad has seeped in to my bones...

concerned that the over sized head-tube to fork transition will look shite.

Need fat crown to look good, or unicrown.

TBH best to ask the builder.

Need fat crown to look good, or unicrown.

Unicrown can look good, @Gandalf ( imo ).

who makes decent quality, relatively shallow profile chainring bolts (need to replace the ones that came on a felt tk3 as they arent shallow enough for DA or Sugino rings). There seem to be lots of options out there but i don't want to end up with soft ones, can anyone recommend any?

That's your Talbot right @BareNecessities ? Lovely, do you have a pic of it next to a 'normal' sized bike - just want to see if it is really as big as it looks , difficult to tell cos it is in proportion unlike many larger frames...

Unicrown might work but unicrown into tapered and curved forks is going to be tricky... have emailed builder @edscoble but believe he is currently bike packing around Iceland.

do you have a pic of it next to a 'normal' sized bike

This is the only one, I think.
