Re: Sand the finish off steerer to help install crown race?

An update. Many thanks for all the thoughts above. I have managed to get the crown race over the collar and fully fitted after using some coarse emery cloth to remove the ED coating from the collar. I also made a better fitting cap for the setting tool by combining caps with one reversed to make a l...

Re: Sand the finish off steerer to help install crown race?

Or ditch that headset and fit one with a split "race" (more properly, a seat for a cartridge bearing). Hope comes to mind, but at a cost, obviously. I have a similarly painted Spa fork and I value the protective coat of tough paint on the steerer. I've already pressed the headset cups int...

That sounds like it's worth a try, thanks.

Re: Sand the finish off steerer to help install crown race?

If the fork is at all valuable, get a shop to run a crown race seat cutter over it. Are you mixing headset components? I don't understand "off the tool" - is this an autocorrect snafu? The complete headset came from Spa, so not mixing parts. I think I've corrected my post, so it should be...

Sand the finish off steerer to help install crown race?

Headset: Tange Terious SRN, Fork: Spa Wayfarer with matt black steerer. I can't seem to fit the crown race to the steerer. I have an installation tool and I have greased the race and the steerer, but it just won't go on despite bashing hard with a rubber mallet on the end of the tool. Was wondering ...

Re: Draggy wheel hub seals

Thanks both for your thoughts. My apologies for not making it clear I was talking about secondary external rubber cap seals. So there's a good chance these will become less draggy with use. Interesting to learn more about the cartridge bearing seals. I shall at least make sure the external bearing s...

It wasn’t advice as such, it was an observation based on the photographs.


You can't read rim size off a tyre which is what greyingbeard seemed to be saying.

Draggy wheel hub seals

I bought a pair of cheap wheels with no-name large flange hubs and cartridge bearings. The rubber seals are really draggy. The wheels rotate well with the seals removed. I am wondering about whether to run the wheels without the seals and lots of grease on the open bearings. Or do I try putting the ...

Re: UN55 BBs not so good anymore?

So I have bought an FSA BB for around 40% of the price of another UN55. It arrived today and looks and feels good. Is that one of those ones in a pale blue box with TH industries written on it? I hope not because I've seen them fail after 6 months. It's a real bummer if the UN55 is going downhill. ...

Re: Average mph difference

The loop has no serious hills in it, but Roland was seconds faster than anything else I've ridden up a 5% 550m section, and significantly quicker (14% / 7%) than either trike along a 4km section with 40m up / 20m down. (Perceived effort was similar, but these are only snapshots.) I'm surprised ther...

Re: Average mph difference

I've been commuting on my AZUB trike this summer and have two weeks of times recorded on Strava. I'll switch to my LWB next week and see what difference it makes.

Re: UN55 BBs not so good anymore?

FWIW if the BB threads are not great and/or you install the unit with either (esp the left) cup too tight, you can exert a mighty preload on the bearings. Put it this way, I have reinstalled slightly worn units and the free play in them has mysteriously disappeared once the cups are 'nice and tight...
