Re: Frame painting

I quite like :D the flip-flop paintjobs which are mainstreaming from the custom car world. Have seen them on a Mini and a Jaguar 8) . IMO, Henry Ford would have sold more Model T cars if he'd offered non-black colours as an optional extra (at surcharge). P. Any Color As Long As It's Black - The myt...

Re: Exploding inner tubes

Thanks for your thoughts. I think the talc idea is a good one. At the moment everything seems okay so I'll leave well alone for the time being. Punctures rarely trouble us (famous last words!) but when the need to remove the tyre arrises I'll make sure its well dusted inside before refitting. Maybe ...

Re: Exploding inner tubes

I agree but the first tube had been in place for about 2 years with no problems. The second was checked after fitting and before inflating. I have never pinched a tube in over 40 years....the last time was as a youngster on my brothers ancient 20' wheel trike! I can still remember the tube balloonin...

Exploding inner tubes

I wonder if anyone has experienced similar and/or shed some light. The first tube went with a seriously loud bang whilst my wife's bike was on the roof rack. It was so loud that we thought it was a gun shot! The tube was a cheapo Taiwanese affair that was well but not over inflated. The tyre (Specia...

Re: Brompton gearing - wide ratio 6 speed?

If you buy your Brompton cheap enough and it has not got the wide range set up then you can go down the upgrade route if it's important to you.

Re: Brompton gearing - wide ratio 6 speed?

The wide range is pretty recent...a Sturmey Archer 3 speed hub plus the Brompton twin rear sprocket changer. The other Brompton six speeds are SRAM 3 speed hubs with two rear sprockets. This is what I have and it's okay for most riding if you have strong legs! This link explains it. It will depend o...

Re: Seat post diameter for 531C

Belated info but when I was refurbing a Claud Butler Majestic enquiries revealed that 26.4 was right! This proved to be so. The Majestic, from the late 70s/early 80s is built from 531 plain gauge main tubes. LBS or potentially expensive trial and error are the ways to go!

Re: HELMET SURVEY & COMMENTS REQUEST

Do you wear a helmet and why? Have worn helmets since the mid 80s (Bell hardshell - very heavy but comfortable fit) Imminent parenthood and a 20 mile return commute in London traffic made me buy it and boy, did the kids at the comprehensive where I worked take the micturate! Still wear one, even on...

Re: Reverse action Shimano derailleurs

Have one of these on my P7. Took a few rides but now really like it! Makes those 'at the last moment' downshifts really easy and smooth! Wouldn't use it with bar end or down tube shifters though.

Re: Ridgeback Panorama

Hi, I have a a Deore rear mech on my MTB. It is a rapid rise, low normal design. I use it with MTB shifters but the same principle applies. The lever that releases the tension on the rear mech spring shifts down the ratios ie from small to large cog on the cassette, The lever that pulls against the ...

Hi,

Have struggled with Marathons myself on a Brompton. Eventually got there with liquid soap to help ease the bead over the rim (easy clean up too!)

Found this though which lists a few suitable tyres but all in the larger size

Good luck!

Just noticed your post re. the crown race. When I changed to suspension forks on my P7 had a new headset fitted at the same time.... had to take it back to the LBS as it was rocking. When they stripped it down they found that the crown race was slightly loose and had to shim it. Has been fine since....

Hi, Might sound daft!!! but have you checked front wheel bearings? Also a real long shot might be the axle. I broke a rear axle on a Campag hub years ago. The quick release held everything in place but it slewed all over the place which made for an entertaining ride home. If it had been on the front...

It looks like you are sorted with the p clips. I had a similar problem with a 90s Orange P7 that I use for light touring.
