I've just changed it so that you now have a week to edit posts... Use this power carefully or you may upset the whole space time continuum....

Astonishing effort from you and the team (and other teams!) Russ!! Fingers crossed for you.

And 77 mph for a girl! Watch out boys...

I think there are a few out-of-joint noses in the Dutch and Italian camps after last night.  My Sinister Agents tell me that:
  • Ilona is 19
  • She used to race cyclocross as a junior and now doesn't
  • She's Fabien's niece, unless she's his cousin
  • She's only been riding any kind of recumbent for a month or so before coming here Clap
  • They had her driving the van again this morning
Colder first thing this morning, and the wind was unkind to almost everyone on the five mile course except, ironically on Friday 13th, Jennifer.  Andrea was the fastest with a 76.96, but he obviously wasn't trying that hard as the team fitted the red nose with the bull on it rather than the faster plain white one.  Neither of Annecy's front-line riders ran this morning, though team boss Guillaume did, and crashed in catch after a 58.5 mph run.  They haven't let him out without the Kevlar crash panels yet.  Rosa failed to launch three times on her first attempt to run and had to try again in the third heat.  Pressure?  Todd got Peter Borenstadt's DF velomobile through the traps at 60.41 mph with a non-legal tailwind.  Much grousing from the Milan lads sitting behind me at the morning debrief.

Among the BRITONS, Russell will attempt to qualify Frankenraptor/Velocitractor/Dinosaur Jr/Bikey McBikeface tomorrow morning as the glue didn't dry in time for today, Ken got to act as test pilot for the latest mods to ARION5's drivetrain and Yasmin's speed would have been enough to break the women's multitrack world record if the wind had cooperated chiz.

The wind dropped for the qualifiers on the short course at the end of the morning proceedings.  Adam Hari's lidless and legal 45.16 mph was enough to promote him to the long course tomorrow morning while the Tokyo team added a bit more bodywork to Haruka 2019 and got down the road at 35.65 after a couple of launch spills.  They've got a tiny amount of ground clearance at the front to the slightest lean grounds the fairing.  Andrew Sourk manages to crash Triage in the 200, climbed out and pushed the rest of the way, but Mr Sir Duke High Admiral Professor Timelord Nogami had already switched off the equipment, so we don't know how slow he actually was chiz.

Aaaaaaaaaaaaaargh - bike fully assembled for 4pm today (Friday), out to Poo Road for practice, back wheel came loose, went to tighten it and sheared the axle. Much swearing occurs here....

New axle currently being machined, but it's getting very last minute now.

We've also got a problem that a slight reduction in wheel movement (side-side) means that we no longer appear to have the ability to flick the bike up off the third wheel, and traditional BM starts are impossible (well for me) with the huge single speed, all compounded by the fact that the new fork has dropped the wheel down 20mm meaning that the lean angle of the bike is increased.  Moving the pivot for the third wheel down 20mm might help, again currently in progress...

And the chain kept jumping off, due it being a f*cking stupid half-pitch timing chain where the teeth are approx 1/3 the height of a standard narrow/wide chainring so any chain slop means the chain happily leaps off the front chainring at any given opportunity.

Build photos here, again sorry for the inability to rotate them:






Much kudos to Barney Townsend (LSBU course leader) for epic amounts of expert bike rebuilding, machining, carbon and fibreglass lay up, keeping the students motivated, etc etc.  LSBU should be incredibly proud.

Barney and I are both properly pissed off/frustrated at the mo, as you can imagine.

Friday night executive summary in descending order of Rubbishness;
  • Rosa Bas: two launch fails in VeloX 9, chain came off on the second, no run
  • Ken Buckley: smuggled into the final heat at the insistence of Sergeant Aten of the Highway Patrol.  ARION5's transmission went "SPANG" after a few hundred yards
  • Personal best for Josh Gieschen in Caly Poly's Ambition, 66.25 mph, illegal wind
  • World Record pace for Ishtey Amminger in VeloX S at 66.67 mph, illegal wind
  • Jennifer Breet: 71.26 mph with the wind speed at the highest possible legal reading
  • Denise Koronek: fell twice at the start, wot is unusual, personal best of 70.60 mph
  • Ellen van Vugt: new personal best of 72.04 mph.  New bike promised for 2020.
  • Fabien Canal: only running on one carburettor due to a nosebleed; only did 83.80 tonight
  • Andrea Gallo: now third fastest ever behind Todd & Fabien with 84.81 mph
  • Vittoria Spada: second fastest woman evvah with 76.98 mph
  • Yasmin Tredell: world record for women's multitrack, 56.42 mph.  Also an outright BRITISH multitrack record, beating the mark set by Russ last year in Greg Cantori's Milan
  • Calvin Moes/Evan Bennewies: multi-rider world record, 74.73 mph
  • Ilona Peltier: women's world record for the second night running, 78.61 mph.  "She can do 80 for sure" says Guillaume de France, grinning comme un fou
This is why we mentally-unstable volunteers keep coming back.

Russ
 
You could machine a plastic chain keep and mount this on the top of the chainring to stop the chain coming off. Alternatively a chain tube will do the same thing when mounted before and on top of the chainring.

re chain problems; a problem with the tension side of  long chain runs is that 

a) they sag when there is no tension and
b) they go almost straight when under tension and

when pedalling, the transition between the two is abrupt.  Stopping a chain flapping around badly between two saggy states is not that difficult, but when the chain is nearly straight it is much, much more difficult via tensioners etc alone.  As Brian suggests some kind of guide is probably called for.

One problem with the small pitch chain is that (unlike bicycle derailleur chain) the side plates are not usually cambered in any useful way, which makes keeping the chain on the sprockets more difficult too. 

  FWIW I have discovered that some 1/8" chains are built using  cambered side plates etc which were originally destined for derailleur chains. The cambered plates plus the additional clearance seem to mean that on a conventional bicycle, using 3/32" sprockets, relatively absurd amounts of chain slack are usually tolerated. You can make the chain come off, but it is surprisingly difficult to do accidentally, when riding the bike.

cheers

Chin up Russ. A great consolation I have found from, ahem, my own experience is that you learn so much more when things go badly than when they go perfectly. Hope this isn't too pollyannaish!

Well, we bloody well did it!

Rear axle re-machined last night, hole cut in hood, chain slightly re-aligned, 3rd wheel dropped 20mm, then out to Poo Road this morning at 6am for practice. A few failed starts, then rear wheel rub/mis-align sorted, and we did a few successful trial runs with and without the hood, and it all started coming together.

Off to the course (15 miles out of town) to just make the last possible qualifying slot at 10:20am. We ran the 2.5mile course, going through the traps in all new Veloci-scrap-tor at 44.3mph.  It felt better, but still bloody terrifying!  I even got a big congratulatory daddy bear hug from Dave Larrington at timing! Big smile

The French team have been unbelievably generous and have persuaded Timelord Jun to move things around so we can run the 5mile course tonight. Big-up massive respect to French team boss Guillaume.

'Tis getting a bit windy now but hopefully will die down for the runs this evening.

ps Hope the Japanese rider is OK, he fainted mid-course and crashed (understandably) and got collected by the ambulance. He was still out when we all left for town, but the Japanese team have reported that he's now concious again.

After last night's excitement this morning was a bit meh, albeit that Russ may not agree.  Wind much the same as yesterday morning's, and the sensible Italians didn't bother to run.  Mike Mowett finally cracked 60 mph; Adam Hari did two runs and got his 55 mph Hat on the second.  Rosa fastest at 74.37, with Ilona second with a non-legal 72.66 and Guillaume a cracking and legal 72.16.  Bill cranked the Milan velomobile up to 60.87 without wind assistance.  Josh got crash of the week after locking up Ambition under braking, rolling a Several of times and finishing only just off the road and upright in the hands of the Cal Poly Oaves.  Denise Koronek got it all on Farcebok Live.

On the short course the rebuilt Velociraptor did 44.38 with Russell at the controls; Kazuhiro did 34.75 before crashing and ending up briefly unconscious.  We think from a faint rather than banging his head, but there were a few anxious moments while the paramedics gave him the once-over.  Guillaume graciously offered his slot this evening to Russ as a tribute to the amazing amount of work the LSBU Oaves have put in this week, though said Oaves claim to have thoroughly enjoyed it and have taken the piss out of the French for getting bored after polishing their bike a bit and pumping up the tyres.

Group photos and handcuffing of various speeding miscreants - Evan, Calvin, Yasmin, Ilona, Fabien and Denise.  The latter since The Sarge decided her exploits at Bonneville last year were a Federal offence.  One more session to go; hoping the wind does the same as it did last night...
