Those of you who are not interested in the technical bits can skip straight to Monday.
A few more words about the Moulton. I mentioned that it was a bit non-standard. Originally, it came fitted with Shimano electronic Auto-D 4 speed gears. I wanted to keep the hub, as it is so smooth and quite. Unfortunately, Mr Shimano has inscrutably stopped making them, so some parts are hard to obtain.
To say I had a few problems is a bit of an understatement...
Problem 1): how to retrofit manual changer in place of the Auto-D control unit, when Shimano have discontinued these products.
Solution: bought a 7-speed changer, and put an old 4-speed bezel on it from a combined changer and brake lever. (unfortunately the numbers don't line up - when it says "3" you're actually in 4th) See photo.
Problem 2): 4 speeds is not quite enough for the hills around here, twelve might be a better bet.
Solution: fit a front triple chain-set, front derailleur, and a chain tensioner.
Problem 2a): front triple chain-rings don't line up with the sprocket at the back.
Solution: fit a narrower Bottom Bracket axle. (but not too narrow, as there is a suspension pivot bolt close by)
Problem 2b): the 42-32-22 chain-set you thought might work is a no-no, because there is a frame brace on the Moulton right where you want to clamp the front changer.
Solution: fit a 48-38-24 chain-set, 24 being the fewest teeth available on a chain-set with 110/74 Bolt Circle Diameter.
Problem 2c): Seat tube too fat for conventional front changer clamp.
Solution: modify the clamp on a 34.9 mm diameter front changer to take it to 38.1 mm.
Problem 2d): No rear derailleur hanger to allow fitting of a chain tensioner.
Solution: Make one by salvaging a rear dropout from an old bike and bolting it onto the inside face of the dropout.
Problem 2e): "Mr Control" chain tensioner a bit lacking in the tension department.
Solution: graft an old derailleur cage onto the "Mr Control" mounting bracket, and throw the other bits into the spares bin.
Problem 3) the resultant 12 speeds is STILL not enough for the Big Hill.
Solution: fit two sprockets on the Nexus hub (thanks to Sheldon Brown for intimating that such a thing is possible). Do this by brazing a 30 tooth sprocket (from a cannibalised screw on block) onto the face of a standard Shimano 18 tooth sprocket.
Problem 3a): Chain catching base of front derailleur cage.
Solution: make cage deeper by brazing a new section 5mm deep to the base.
Problem 3b): how do you select between ratios on the new "Club 18-30" rear sprocket cluster?
Solution: Fit old Sun Tour rear derailleur and friction shifter from spares bin.
Voila, 24 gears! And it goes up the Big Hill! OK a few niggles, like some "grinkling" in certain gears, but it works.
The observant among you will have realised that this bike now has no less than 3 GEAR SHIFTERS! And you would be right! (Y'see, the volume on this Moulton goes up to 11!). See photo – two twist grips and a friction shifter, beat that!
Testing Moulton on the Big Hill.
Time to summit (or somewhat near the summit) 25:40 (with one stop to put the chain back on, after it fell off of the “Club 18-30” rear sprocket).
Max speed down the Big Hill 39.9 mph. Relief at stopping OK at the bottom. Bremsstrahlung!!! (Check that one out, Microsoft spell checker! Hah! Got you! No suggestions!)
Problem 4): how to fit a rear rack
Solution: too mean to buy the authentic Moulton rack, buy one that's designed for a standard suspension mountain bike and spend hours making some steel mounting brackets.
Problem 5): Do you really think this Heath-Robinsonish contraption is going to last the distance from Lands End to John o'Groats?
Solution: back to the drawing board.
Monday 14th May 2007
Been very rainy over the last 24 hours (started yesterday lunchtime). The forecast suggested it might have cleared by this morning, but I very much caught the tail end on my way in. Managed to get the Lead Balloon up the Big Hill and Hillockplex in 27:50, which is probably a best on that bike. Of course, this was all down to some wind assistance, as the wind has gone round to the North East and is blowing all those ragged rain-clouds back down the country from whence they came (should that be "to whence", or just plain "whence"?)
The tyre dumpers have been out again - this time distributing them every 50 yards along the side of the road.
Becks are swollen, and water roaring through culverts. The wind is cold: my left nasal passage gets that feeling when you've just scoffed an ice cream too fast.
As I skootch through rivulets of rainfall running off the moors, I find myself reflecting on our very poor showing in the Eurovision. Obviously much of Europe just didn't get the innuendo of some of the lyrics, which were in the tradition of Julian and Sandy on Round the Horn. I suppose having to follow the high camp effort of the Ukraine entry, made our entry seem a tad too subtle. Not sure why Andorra (population 73.5) gets the same voting power as say Germany or Poland. I say it's time to lump all the telephone votes from every country into the same bucket, and just make the winner the entry who got the most telephone votes. This would cut out all those tedious congratulations when the scores come in from each country.
Any-road-up, so I'm "Flying the Flag" as I go down Pellon Lane into town, which lifts my soggy spirits.
After tethering my steed, I come to the lifts, and they're both there. Rapunzel 2 already has three people, so I lurch in Rapunzel's direction. I guess I've taken her by surprise, but she still tries to close her doors on me as I stride inside. What more proof do you need?
Today’s vital statistics:
Rapunzel (1)* - Rapunzel 2 (2)
* not summoned, so shouldn't count.
Time out: 0:54 (another sub-hour showing - must be improving)
Ah, relief, dry and sunny, but a bit of a Nor’-Wester’ now, threatening heavy showers, which fall elsewhere. Even employing my best aerodynamic tuck, can only reach 30 mph coming down into the village, such is the head-whinge.
Time return: 0:57 mins (pretty creditable)
Tuesday 15th May 2007
30 minutes up the The Big Hill. Today I feel out of tune with my bike. This is probably down to the wind which has gone round again.
Lambs still curious, they look at you as you pass while their mothers munch impassively, making milk.
Tyres in a watercourse and someone has dumped a bit of rusty motorcar further on. Do these people not realise they can dispose of stuff like that at the dumpit site? I recognise the scrap metal as a Sierra rear subframe with differential and prop-shaft. I used to have one of these (not the car, just the sub-frame) when I was building a kit car. This was in the days before I realised that cars are not the way forward.
A grouse diddles across my path a few yards ahead. He stands at the edge of the road playing I-spy with my little eye. In a little under three months he won't be hanging around on street corners; he'll be just another gun-crime statistic.
At this point let me point out that I am not a practising vegetarian, but I do get veggie tendencies at times. I pay to have animals killed for me by someone else, and suffer pangs of guilt when I eat them, as did the Walrus for the oysters in Alice:
"I weep for you," the Walrus said:
"I deeply sympathize."
With sobs and tears he sorted out
Those of the largest size,
Holding his pocket-handkerchief
Before his streaming eyes.
"O Oysters," said the Carpenter,
"You've had a pleasant run!
Shall we be trotting home again? "
But answer came there none--
And this was scarcely odd, because
They'd eaten every one.
Scores on the (lift) doors:
Rap (1) - Rap 2 (2)
Time out: 1:00 (we were never going to break any records today).
Way back: sunny, but not too hot, favourable wind, overflown by 2 oystercatchers, 41.2 mph into village, what could possibly spoil this idyllic, er, idyll? Answer: swallowing a fly at 41.2 mph!
Time return 0:55 (What do you run on, Rockette Morton?)
Wednesday 16th May 2007
Last night I tinkered with one of my ever-increasing collection of mirrors – the “Avenir Bar End Mini Mirror” (“Note convex mirror gives larger viewing area but can make images look smaller”). It has a bendy arm, so you can set it to any angle which turns you on. “Will it bounce a bit with that flexible arm?” I had asked the bike shop proprietor before I purchased it. “No”, he lied. So I handed over the dosh (£11.99 for a pair).
The convex mirror makes cars look so far away that one moment they’re a very small pussy-cat, the next they’re upon you like a lion on a wilderbeest. Anyway, I was sure I could improve on this mirror, simply by shortening the bendy part by about an inch. What I should have predicted was that shortening it would change the resonant frequency. Where previously it used to dance, duck and dive like Mohammed Ali in his heyday, now it dithers like Lee Evans on speed.
Before setting off this morning, I decided to jack up the saddle a whopping 2mm. Felt slightly more 'comfortable' (not sure if that's the right word) on the Big Hill. Still took 30 minutes to top, disappointingly.
Plenty of larks and pipits sounding off overhead.
Overcast and cool, just the wrong side of pleasantly.
When does a "cycle lane" become a "cycle route"? The criteria could perhaps be, length, width, location? The implication is that some planning has taken place, and that by using it, you will arrive at some sort of desirable destination. The cycle routes along the 200 mile length of France's Cote d'Argent spring to mind (which the four of us cycled in 1999). So it's a little disappointing when this one stops after 0.3 miles, just short of the Newsagents. I'm talking about the pitiful effort from Mount Tabor in the direction of Halifax which is terminated by a sign proclaiming "End of Cycle Route". Pity the Trades Descriptions Act doesn't apply.
Is it me or is everyone in a hurry today? Cars seem to be roaring around, especially the turbo-diesel 4x4 jobbies. One puny person going from A to B, lugging two tons of steel, glass and rubber, seems a bit excessive to me.
Rap (1) - Rap 2 (2) (We are definitely out of favour with Rapunzel I will say no more on the subject).
Time out: 0:58 (verdict: an easy downhill second half to the run)
Just got home before the rain set in for the evening. Yey!
Succumb to “Stayin' Alive” by the Bee Gees (I sing it to ward off evil road-spirits).
1:03 return (via Flappit)
