Lifted from ClassicRendezous:

• There is a date stamp on the back of 1973 and later NR/SR cranks. A number in a diamond represents a year in the 70's that the arm was made. A number in a circle represents a year in the 80's that the crank was made. Either "11" or "22" in a box represents a production run, probably mid 80's that was pretty much the last of the NR/SR stuff. Perhaps some of these late items were warranty stock? Don't know for sure...

• 1978 was a big year of change for NR/SR. CPSC mandated that the front derailleur have a "lip" on the leading outer edge so nobody would impale themselves on it - Never mind the big aluminum disc with sharp teeth - or Huffy's!

Now we can tell the true NR/SR BB Road Spindle Story!

To accommodate the CPSC front derailleur lip, the distance between the arm and spider of the crank had to be increased, which then meant that the bottom bracket had to be lengthened too! The result is that the arms were redesigned - older pre- CPSC right arms can be identified by a relatively large bulge of relatively larger diameter on the backside where the spindle enters. Later arms have a smaller bulge of smaller diameter. The changeover was in the 1978-79 period. Early cranks use bb spindles with markings such as 68ss x 120 or 70ss x 120, while the later cranks use slightly longer spindles that are marked simply 68ss or 70ss. Some transition era spindles carry the designations such as 68ss x 120 AND have +1 /+1.5 markings to the side of the 68ss x 120 or 70ss x 120 stampings. That means that the spindle is the same as the later ones without the 120 designation. Use of a later crank on early spindles usually caused the crank to hit the frame. Use of the later spindle on an early crank pushes the arms out farther than optimal - but if using on a 6 or 7sp, or if the arms are worn, then the chainline error may be minimal - this combo may in some cases even be better.

THE UPSHOT is that the 120 designation does not, for practical purposes, refer to rear frame spacing - the issue to worry about is era of crank.

Use of derailleur with lips on early cranks is a leading cause of grooves being worn on the backside of the drive arm. Keep those lips off our early cranks!

That is a good shout, Hippy. I did notice the other day that he had whacked up some "I'm on holiday" text on his site, but that's down now so I'll assume he's back.

Will post any advice given!

[size=10]Anyone??

Hippy, when I did the Dragon in '05 you had to register the day before. I think last year a few entries were allowed registration on the day, maybe more of the same next year.

I stayed in a Travelodge near Swansea the night before, only cost £7 or something daft like that. Few funnt faces as I wheeled my bike into my room for the night, I was taking no chances leaving it in the boot of my brother's car!

I just did top gear london bike or top gear london race search on youtube. First set of links where blocked waited 10 min and the tried again and a new set where up. Or try google video.

It's not that, Youtube is banned completly, but if embedded in a topic as above I (and Brett!) can view them, hence I've only been able to view the first part.

The Dragon Ride in south Wales is a great sportive, next year's date is 15th June.

Hard, long hills.

Dragon Ride on BikeRadar

Calshot do taster sessions similar to Herne Hill.

I went about 6 years ago for my first (and only) experience of track riding. I went as part of a track session with Glendene, luckily an an old friend of mine used to do some riding for them so I managed to get into the session. I slept all the way home in the car!

Any chance you could ingress/regress/whateverthefcukitscalledgress the other twi vids? Youtube banned by work, so only managed to watch part one!

Muchos thankos!

Does anyone happen to know what the 'a' stands for on an old school SSa bottom bracket??

Cheers!

Great stuff BMMF. From a personal point of view I have a tip for myself. Lose a stone! When I go on a big diet I drop to 12st 4lb and feel great, currently weighing in exactly 1 stone heavier.

For Hippy et al, 78 kilos ideally, currently at 84! Fat fcuker. Big ass. Etc, etc.

Found the following webpage from Bikeforums.

Lovely looking bike, well done! I have an Olmo built from around a similar period, the Columbus SLX tubing handles great and feels lovely. Sadly it came with some cheap aftermarket carbon forks, since then I've been on the lookout for an original pair!

Anyway, I'm off now for my 24 minute 'legal' ride from Gunnersbury to Victoria station. Fast enough for ya, Hippy?

The stock optional extra on a Brompton is a Schwalbe Stelvio, although you can also get the Schwalbe Marathons from other stockists. The Marathons are 1 3/8", not sure on the Stelvios. Pump the fcukers right up and they end up pretty narrow anyway!

eeehhh, have you saved an inch and a bit by clamping the saddle bracket as high up the seat tube as you can?

Hippy, if you get the set up right (basically meaning the saddle height as that's all that can be adjusted as standard), then they're good for however long you need to ride them. I'd advise getting a 6-speed as the gaps in the gearing between 2nd and 3rd are ridiculous, into a big headwind you're either pedalling like you're towing a piano, or your legs are going like the clappers like you're riding a 40" gear.

The S-Type mirrors a road position best as the bars are lower, it also makes it easier to honk on the bars.

The only issue is the tricky handling, especially in the wet. Every manhole cover, painted white line, or pile of leaves is like riding on ice!

In fact, I'm planning to do the L2B on my Brompton next year, all for charidy.

Bizarre to see that most pics of BMMF are blurred!

Winston, I think he was rider number 43, clocked around 2 mins 30. Flew up the last section!

Hippy, yes.

Good plan! To smarten it right up though before selling, SJSCycles do replacement handlebar grips in the grey, about £2 for a pair.

Bargain! Is it an S2?

Got an S3 myself, got it on an insurance job after my older T3 was stolen.

18 months old now, same as the pic apart from the saddles is now a 'normal' one after I broke the original riding pished one night shouting at all the traffic along the A4 and the bottle dynamo is no more after the bracket holding it on sheared off about a month ago!

Almost took Brett going up Highgate the other month, but to save him embarassment I gifted him the 'win'.....

Yep, Chapeau BMMF.

I took in Yorks Hill before the event and also clocked a PB, mine being a gentle amble (!!!) that took 3 mins 39 secs. If I knew they were selling burgers at the top I would have shaved a minute off. Did any LFGSS attendees (apart from BMMF) have a crack at it after the hillclimb?

I'm not entirely sure of the section out of London, but being a Kent boy I can tell you everything you need to know about the route once you enter God's own garden.

There's a short sharp rise of no more than 300 yards just before you pass Biggin Hill airfield. Once past the road rises very gradually all the way through Biggin Hill before the plunge down Westerham Hill, incidentially written about by Matt Seaton on the very first page of The Escape Artist. It's then lumpy but mostly on a slight downhill through Brasted to Sundridge where you'll chuck a right up New Road. The road to Ide Hill begins with a sharp section but then is a very gentle rise all the way to the top.

See you all there!

That is a lot of money! For the record I picked up a virtually brand new C-Record BB for my road bike from the States for $50 last year.

If you're not sure I'd suggest buying a second hand, well worn BB, and fit it to check the chainline. From there you'll know where you're going with it. Even if the cups are Ok, but the axle is shot you could just pick up another axle from a bike jumble. I do have a spare BB knocking around, but it's for an Italian shell, sorry!

Oh I enjoyed it all right, but only about 5 minutes after I reached the top!! No wonder you hear so many cyclists coughing throughout October and November.
