Re: Play in (tapered) integrated headset cartridge bearing?

You are correct in thinking that the fork in the photo has an integrated crown race and any crown race supplied with a headset shouldn't be used on top. The external bevel of your lower headset bearing is 45°, so you could try inverting the lower bearing and offering it up side by side to the fork c...

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: Spare Tiagra Cassette - can I choose any?

Look up b-tension adjustment too- if your chain is the right length but it feels rumbly on the biggest sprocket you may need to screw it in so there is a bit of clearance between the largest sprocket and the guide pulley of the derailleur.

Re: BB Spacers

Looking at that photo it doesn't look too bad to me actually - is 4mm of the actual crank spline visible (it doesn't look that much to me but it might just be how I'm seeing the photo), or 4mm to the outside edge of the crank? You need at least a mm of spline showing inside the crank to be able to p...

Re: Which dynamo front wheel would be best to buy for my sons 26" wheel bike

Yes I've had that Zac 19 Taylor Dyno wheel for a couple of years. Again no issues, build has been fine, even the cheap Shimano hub dynamos are very well sealed, and put out plenty of power at relatively low speeds. No real reason to spend more unless you want to. 2mm rim width difference means a sim...

Re: Sticky STI levers

This is the bike, it's only four months old, and I bought it from Argos for £350 which I'm betting you'll tell me is why it's crap. :D Buying cheaper bikes, especially from non-bike shops, you always have to factor in the potential cost in money and/or time of getting assembly problems sorted out, ...

Re: Don't laugh - bike noises/clicky-whirry noise when pedalling and not pedalling

Is it a hub geared bike? And does the rate of clicking vary according to what gear you're in? If so this constant clicking is the sound of the inner workings of the hub gear. It is how the bike works. It's really best to post a video of your actual bike rather than that of a different bike on the in...

Re: Spare Tiagra Cassette - can I choose any?

Am I correct in thinking that you want to run one cassette when on the trainer and another on road? If you use 2 quite different cassette ratios you might have to run a sloppy chain on one to accommodate the one with bigger large sprockets on the other. Also b-tension screw setting on the derailleur...

Re: Too many broken spokes on handbuilt wheel

It's not really surprising given that you have spam spokes. It doesn't have a very high tensile strength and if left in storage may get nibbled. I'm sorry I have nothing useful to contribute :| Seriously though it sounds like the wheel is built or specced/laced wrongly/unsuitably. Either that or it ...

Re: Upgrade 11-28 to 11-32

It will have the model number somewhere, all Shimano components do. It's probably on the back of the parallelogram assembly. Maybe the SS/GS isn't in the code, I guess if that's the case it's because the derailleur bodies are the same and the cages are swappable. But this is a picture of the two typ...

Re: Upgrade 11-28 to 11-32

It should be ok as long as you don't have a short cage mech. I don't think a hanger extender increases the capacity of the mech, it just means that maximum sprocket size is increased which is not the same thing. I would have thought that capacity stays the same. As you are presumably running 11sp th...

Re: Dawes

Wow, I wasn't aware of this, it's pretty sad. We've had loads of Mojaves and some discoveries as fleet bikes and I wasn't impressed, but I always assumed they were still making good bikes as well. Going the way of Muddy Fox etc.

Re: Surly fork crown mounts

The lo-rider bosses on a LHT are, annoyingly, in the wrong position for a Tubus Tara. The mounting rail ends up sloping backwards. That's weird, there should be enough adjustment in the attachment points to get the rails level, unless they are inverted and fitted on the wrong side of the fork. Some...

Re: free hub issues again

A collegue looked at a rear wheel for a customer the other day, the freehub felt completely free out of the frame. It turned out to be a slightly displaced seal on the back of the freehub that was causing the binding when clamped in the dropouts. Could be this, or perhaps a cartridge bearing in the ...

Re: Surly fork crown mounts

Great, thanks! I think that half of those mounts on the ogre fork are also for anything cage type affairs. They make it look like it's got ugly ogre pimples!
