I've run 700 x 25c tyres for years but I recently decided to try a 700 x 28c Shwalbe Marathon Plus which is also marked 28 x 1.10, 28-622. I used Schwalbe inner tube which is marked as suitable for 700 x 18 to 700 x 28c and the rim is a Mavic Open 622 15C.
I pumped the tyre up hard using a Revolution mini track pump and within a few seconds there was a loud bang and the tube had pushed the tyre off the rim and there was a 3" -4" gash in the tube. My initial thoughts are that the tube is not of a large enough diameter, it looked small inside the tyre. I think it was stretched too much, it's claimed size range seems to be too ambitious. Does anyone have any thoughts on this? I had been using this tube with the 25c tyre with no problem.
Also I'm using Shimano deep drop dual pivot brakes which work well on this rim with 700 x 25c tyres but with the 28 one brake pad only just misses the tyre whilst the other just catches and both are at the bottom of the slot on the caliper. I could be tempted to trim the edges of the pads with a Stanley knife unless there's a good reason not to?

FFCT Semaine Federale
I have been looking on the FFCT website http://sf2017.ffct.org and it says that you can register and submit applications to attend online but I can't get any further than that and it would be helpful to have the English version. Has anyone else had this problem?

Re: Recovery time when getting older
I'm 58, in June I will be 59. I do Bikeability cycle training in schools and I cycle to schools whenever I can. Mostly the furthest school away is 10 miles but I try to put a loop in after work and make it up to 30. Yesterday I did 36 miles, today 37. I don't work in the school holidays so then I go out on longer rides. Sometimes I ride with my local CTC group and this year I've already got some 80 - 100 mile rides in. I'm not a racer but I'm not slow either and so far I don't feel any more tired than I ever did. I think that keeping going helps, there have been several reports that if you cycle regularly you are 10 years younger than your actual age so really I'm just a young whippersnapper!
Two of my club cycling mates are 70 and they can do the mileage on clubruns no problem and they ride midweek too, it's great what you can do given the time.

Re: Bicycle pump.
Edinburgh Bicycle co-op do a Revolution which is like a mini track pump, I've had one for years and i use it for all my pumping, I have found that I just don't need a full size track pump anymore. It's probably about £20 but sometimes they have a sale. As for any kind of pump failing to get up to pressure try taking the gromits apart and apply literally a drop oil, it acts as a sealant and prevents air under pressure escaping.

Semaine Federale
It's been nine years since I last went to the Semaine Federale and since then I have heard rumours that the FFCT planned to limit the numbers attending. Does anyone know if they implemented this?

The letter asking for a bequest went straight into the bin as I'm sure it did for many other members too.

Surely they are recruiting for "Cycling UK" whatever that may be.

Re: Car Insurance
It is wise to check out things like Insurance, gas and electricity suppliers. As for the internet, it is wise to check out exactly what you are getting before jumping. If you go to www.cable.co.uk/guides you will find out what the ISP's are really offering, or not as the case may be. It is better to make an informed decision rather than listen to sales talk and maybe pressure!

Thanks for jogging my memory Paul and Gaz, it was indeed carinsurance4cyclists.

Re: Do we need a new Cyclists' Touring Club?
AUK is closer to the traditional aims of the Cyclist's Touring Club than "CTC", whatever that means, is.
They have well organised and attended rides, offer free 3rd party insurance and have a magazine which is more akin to "Cycletouring" than the present "Cycle" is.
Of course their longer rides are a bit further than most would consider to be touring.
I am not an AUK member, just making an observation of the present state of play.

Car Insurance
I don't know where else to put this on the Forum.
A few months ago, probably on cycle clips, there was a link to a firm offering cheaper car insurance to cyclists. I can't remember the name of the firm but I wondered if anyone had got a quote or taken out the insurance?

Re: Best tyres for European road tours
Like many I use Schwalbe Marathon Plus, I like the almost total resistance to puncturing, I haven't noted any difference in comfort and as for rolling resistance Chris Juden commented recently in "Cycle" that as a tyre wears the rolling resistance decreases, that seems to make sense as there is less compound to drag. As for having a lighter tyre on the front consider this: your rear wears faster than the front and at some point you can swap them around to even the wear out but you will need the tyres to be the same.

Ceramic chainrings
I have noticed that Stronglight do some ceramic chainrings, has anyone tried these? Are there any problems with them and are the worth the difference in price? I presume that there is no problem mixing them with, say, Zicral chainrings on a triple chainset and that they fit a standard alloy spider.
