Re: Which Forks?

Your original (blue) forks are inch and eighth straight steerer, and so are the black steel forks.
All you need to do is swap the fork crown race over. (apart from considerations of axle to crown race seat length and offset)

Appreciated.


don't do this. The rear will lock up too easily. If you are going to improve just one brake, make it the front one.

Re: Toe Overlap

Bearing in mind I am no athlete, if toe overlap is an issue on a bike, would replacing the forks with a more “bent” designed eliminate this ? I understand other things would change but considering I get on well with a wide range of bikes including a 1931 sunbeam gents tourer I am used to “odd handl...

..........The muscles in the hands are so much smaller than those in the shoulder and upper arms, that it seems to me that they must exert significantly less force......... We are a long way from "how to get your lockring undone", but this is wide of the mark. The main muscles which flex ...

Re: Mudguard screws sheared off and embedded in frame

M5 bolts are pretty small to get a stud remover into; I would first try left hand drill bits....exactly what it says....they drill counter-clockwise, and as they "bite" they tend to back the bolt out. If they don't back the bolt out, there is nothing lost, you can still try stud extractor.

Re: How oh how do you get a lockring off?

What does the team think? What immediately struck me when I looked at your photographs was not the positioning of the tools, but the length of the handles. Your Bahco adjustable spanner is 15"/380mm (and googling reveals they also make an 18" / 450mm), and even without the scaffold pole e...

Re: How oh how do you get a lockring off?

I think that the wear arises from small radial movements of the sprocket under load, and that if the clamping force is enough to suppress that most of the time, it is 'job done'. .... .......... I would probably have designed the spline with sloping faces rather than radial faces; this woul...

Re: How oh how do you get a lockring off?

.........You can check how tightly held the sprockets really are by using a couple of chain whips; they will move within the spline backlash, at a torque which varies with the clamping load..... All my freehub bodies are steel. Even with cassettes built up from bits (ie no rivets), all I see are br...

Well done to the OP for getting the blasted thing undone. :D :D :D I have taken some photos, so I'm going to show them....spurred on originally by Jonathan's challenge (?) to take some photos, then by others comments on how tricky chain whips are to use, and how we should stress them in just the des...

Re: How oh how do you get a lockring off?

Have you tried getting the handles of the tools aligned so using both hands you squeeze them together to loosen. It’s worked for me in the past and my favoured position for pedal loosening. ^^^^THIS. Squeezing with both hands you can exert a lot of force. (OTOH I undo pedals by strapping the opposi...

Re: How oh how do you get a lockring off?

If possible hold the lock ring removal tool in a vice, place the wheel onto it and turn the wheel. It usually works for me. No, you must turn the cassette with a chain whip. If you turn the wheel, you can tighten the lockring, or going the other way it will freewheel. Unless you have a freewheel bl...
