Re: Brompton cycles choices

one thing that those who advocate adding bars ends dont realise that on drop bars the most useful part is the curve between the tops and where the brakes are - this is probably the best postion as the palm of the hand falls there naturally? that is the bit I would miss a lot on flat bars of any kin...

Re: Brompton cycles choices

Possibly a bit late, but on the M vs S handlebar question one thing to note is that you can't use the largest Brompton front bag with S bars. I've ended up with an M type Brompton that I swapped the handlebars on so that I could fit bar-ends. This has worked really well for me and I've stuck with it...

Re: How good/strong are Brompton wheels/rims?

Not directly wheel related, but worth bearing in mind that according to Brompton the maximum recommended weight for rider and luggage is 110kgs. Depending on how heavy "heavy" is, that may be a factor - https://brompton.zendesk.com/hc/en-us/articles/203296301-What-is-your-recommended-maxim...

Re: Hub gear issue

In case it helps anyone else, it does indeed seem to have been due to adjusting the cones in the wrong order. I couldn't undo the planet cage so it still moves on the axle (when both cones are loose) but setting the righthand cone first seems have moved the cage into the correct position. I've used ...

Re: Hub gear issue

Thanks Brucey, the two times the plate has got mangled it has come off, but I don't know whether it fell off, then got mangled, or got mangled and then fell off! I'll take the planet cage out when I get some more time and have a look at it. It's the one piece I've never taken apart as I wasn't able ...

Hub gear issue

Hi, I'm hoping somebody here can tell me why since I last serviced my 3 speed Sturmey Archer BWR hub I can't go more than a couple of miles without destroying the driver actuator plate. I have taken this hub apart and re lubricated it a couple of times before without (obvious) ill effects, but now h...

Re: Insuring a Brompton

I take a Brompton on the train each day and I lock it (folded) to the luggage rack if I sit down. It will depend on the train you use but you may be able to do the same. In a pub etc it's harder but so far I've just put it in a corner next to me, I do tend to go to pubs only with large groups though...

Re: Wide range hub gear servicing problem

Thanks, I followed 1 & 2, 2 was tricky I had to hold the axle and cone with two spanners whilst turning the lock nut with a third spanner. Still after tightening there was still a tiny bit of play. 3 and 5 don't seem relevant to my hub. For 4 I used the proper internal grease in the hub, and a w...

Re: Wide range hub gear servicing problem

So I took the hub apart again today and had a play. With the axle in a vice I held the driver still and turned the ball ring clockwise to simulate the wheel turning whilst freewheeling. With no pressure on the clutch spring (middle gear) the ball ring turned easily. The planet cage went round with t...

Re: Wide range hub gear servicing problem

You can put x2 or x3 the normal quantity into an SA hub and any surplus might leak out in use (the grease in the ball-ring is being sheared, so can move freely when the bike is ridden) but the hub won't be likely to run dry or anything like that. Do you just use the thixotropic grease for everythin...

Re: Wide range hub gear servicing problem

The hub should freewheel by overunning the pawls on the ring gear assy. Thus freewheeling by the clutch overriding the planet dogs is not normal, and usually indicates that the gear ring is being dragged round by the hubshell somehow. Thanks a lot Brucey, I don't think that the clutch is overriding...

Re: Wide range hub gear servicing problem

It is sometimes possible for the clutch to overrun the planet engagement when coasting, but IMHO this usually indicates a lack of running clearance on the RHS, and/or lubricant that is too thick and gungy; both can cause the planet assy to drag round with the hubshell. Thanks Brucey, I think the be...

Wide range hub gear servicing problem

Hi, So I thought it would be a good idea to try and service my brompton wide range hub gear myself, partly to save a little money, but mainly to see how it works and to get more practised at general servicing. So I took it apart, wiped off the old grease, applied new grease and re-assembled it. I fo...

Re: Different brake levers for Brompton

I've also got Shimano BL-R550 on my Brompton and they are much more solid than the old style Brompton levers. I don't know whether they are actually any easier to pull though. One thing I found when changing the levers was that the angle of the lever on the handlebar makes quite a difference to how ...

Re: london stations' policy to carry folded bikes

As someone whose exit from a train has been brought to a premature halt by the insistence of a Brompton owner to unfold his bike immediately on vacating the train in the vicinity of the door it does occur to me that perhaps the train companies are simply responding to complaints? I was told it was ...
