Fitted ok, though I left the bolt through the front fork very loose as it needs to come off again and get shortened.

As it happened, as would be predicted by the Law of Universal Cussedness, yesterday was dry and the entire exercise so far pointless, but it was quite good fun searching out the odd puddle and slurry-stream for a change.

I noticed that if I took one hand off the bars the mudguard vibrated about. Putting both hands on stopped the vibration. This was quite consistent, and easily repeated. I then noticed that taking both hands off also stopped the vibration.

I assume that this has always been happening, but escaped notice without a rattly mudguard available as an amplifier.

I have four bikes. All have mudguards.

Re: What windspeed would you class as heavy going?

PhilTheFish wrote:Hi all,

This is my first year commuting by bike to work (15 mile round trip). I've been doing it for around 3 months now. The first couple of weeks I struggled with so much as a mild breeze in my face but have now got over this.

One day a couple of weeks ago the wind was so bad that I was having to lean into a crosswind to keep me upright. I didn't enjoy that ride home and would endeavour to avoid it in the future.

My question is, when watching the weather forecast on TV the night before riding in, what sort of windspeeds would you class as too difficult (or dangerous) to ride in?

I know this will vary from one person to another but I'm looking for some sort of benchmark to work off.

Phil


Hello,
I usually find that 12 mph and over make things harder. But 20 mph is not worth riding in.

Update:
Had another long day in the Inquiry and have yet to give my own evidence. John Franklin did give his and he was excellent. He got across the point how dangerous these grids will be to cyclists, despite a tough cross examination by the AONB barrister. It is a pity some prat at headquarters sort to give the other side a hand up without even discussing the issue with me.

Because I am still needed tomorrow at the Inquiry, I have had to put back getting my legal advice until Friday.

Ain't it amazing how quiet HQ goes at times like this. No; I suppose it is not really surprising as it don't enhance image and don't attract government funds.



Hello,
I personally have some issues with CTC HQ too. I have found out that CTC can take ones money and when they are needed to help, noone is at HQ to help! Even the so called Insurance (Free?) now has an excess which would probably cover most damage done by a bike to another vehicle. In my opinion CTC has become establishment and no longer a Cycling grass roots organization.
I am not surprised with what has happened here, just saddened.

I used citrus degreaser which I rubbed on and rubbed on and then wiped off with a damp rag. Both of which came out as black as anything even though they don't look visually too bad. After about half an hour of this I gave up. My brakes were a bit better this morning but not a lot. Any tips please.....

Unsprung (Brooks again) with suspension seat post (USE).

Intended use is for touring with flat bars.

Grateful for views.

In my own experience as a dyhard Brooks fan I have three bikes with B17 Specials, but my more upright sitting position Thorn Sherpa has a Brooks Flyer. It does the trick very well indeed. No breaking in period and hardly any 'bounce'.

Re: Chainset Compatibility

simont wrote:I am attempting to upgrade/liven up my 20 year old Dawes Super Galaxy. I've got Shimano 8 spd bar end shifters (front non indexed), HG70 11-28 cassette, sram chain and ultegra (double)front and (long) rear mechs. I want to fit a compact chainset but all those of similar quality to the other components (Centaur, Ultegra, 105) are 10spd. I have been given conflicting advice (from reputable shops) about what will work. I've been told:
1. Any 10 spd chainset (campag, shimano) will work ok
2. Shimano will but campag won't
3. 10spd chainset won't work with 8 spd (because of the chain/chainset incompatibility)

I don't want either to upgrade to 9/10 spd because of expense or to fit a new triple chainset. My first choice would be the Campag Centaur Compact if it will work ok. Can anyone help please?

Hello,
ANY chainset will work with your setup. Just go for what YOU want but if going for a compact (which to my thinking is daft as you should go for a triple) make sure that you have the correct (suitable) front gear mech.

vandjq wrote:Hi John,

Thanks for the prompt reply. That takes care of the stays, but how do I attach the top of the mudguard to the fork, unless you can get suspension forks with pre-drilled holes?

The top of the suspension fork has a brace which goes from one leg over to the other. Where the brake cable end would go if you used cantilevers, you drill a hole. There might already be a threaded hole for canti cable stop.

Yes I do.
You need a couple of large Cateye light clips made of plastic. The kind which have a screwdriver slot to adjust (like older pump clips). These you fit round the suspension part of the fork near to the bottom. Then fit the mudguard stays to the flap .
Once you have the clips fitted its pretty obvious.

Hello,
I have three Thorn bikes! I did have five. One Sold was a Thorn Raven Tour with Rohloff. It was not for me. I also Sold a Thorn Nomad to fund the Rohloff bike. I regret the sale of the Nomad. I do not miss the Rohloff. I would not buy another brand again as far as I can tell from a number of Years with Thorn.
Just my own opinion of course, the same as the rest on here.

Re: £20 Ron Hill cycling shorts - AVOID

fatboy wrote:For father's day I got a present of a pair of Ron Hill cycling shorts, and they haven't lasted well at all. The first pair I got replaced after the stitching in the pad came adrift after a couple of months. The second pair only lasted one day! So I got my money back and bought a pair of Altura shorts instead.

As a general note about Ron Hill kit. It used to last for years. I have pairs of Ron Hill tracksters from the early nineties which are still going strong. The new ones that I got in the early two thousands have all gone to holes. Running shorts that I have had haven't lasted well. So here we have a once good quality company now pedalling poor quality stuff. AVOID!


Hello,
I have and use Ronhill shorts. I have done for over 12 Years. No problems at all and if looking for new I shall buy again. At present I have 7 pairs in use.

Is a folder like this really up to loaded long distance service?

Re: 130 wheels in 135 drop out?

andyh2 wrote:OK I had no problems fitting 130 wheel into my 126 drop out steel frame.

I'm soon to get a 135 drop out steel frame. I'm assuming that being only an extra 1mm difference the 135 drop out frame will accept being squeezed down to accommodate 130 wheel.

Is my assumption correct or is reducing drop out width problematic compared to widening it?

Hello,
I assume a Thorn or Hewitt?
Firstly it will work butbeware I have tried this and it does the rear end of the bike no good at all (thats if its a Thorn) because the rear end is verystiff.
It would be much better and nicer and much more sensible to wait until you have or can now afford, a 135mm hub.
Good luck with it,
John.
