Tour of Wellington day 2

Stage 2 of the Tour of Wellington led the boys over 127 kilometers of the Wairapa countryside including the nasty Limeworks climb and finishing at the top of the 12km Admiral Hill.

The pace from the gun was high and the first hour of racing the boys had covered more than 41km…impressive when you remember the first 5 km was under neutral!  Early breaks were trying to get away but the bunch wouldn’t let them and the first 60km flew by.

The heat was taking it’s toll and we were called up a few times in the team car to provide water for our riders.  All of the boys were going well and they handled the high pace and stayed really calm.

The bunch stayed together until Limeworks – this was the first big climb of the day and those with an eye on GC took the opportunity to tighten the screws.

After a hair-raising descent back to the valley floor the last climb up Admiral Hill began.  Our guys climbed really well and Andy was the first of our team across the line about 6 minutes down on the stage winner, Michael Tockler.

Tomorrow is a long 165km stage up to Pahaitua – it’s going to be fast but after a wicked spagbol for dinner the boys will be ready :-)

Tour of Wellington day 1

Today was the first stage of the men’ s Tour of Wellington – I’m managing team BP consisting of Mike, Daniel, Jono, Andy and Chris.  For the first time in many years the race started in Lower Hutt and headed over the Rimutakas.

The race was neutralized until the base of Kaitoke and within a few minutes of the flag dropping the attacks started.  The pace up the Rimutakas was high and within minutes riders were popping off the back.

Drapac Porsche were responsible for most of the pace setting and managed to get two riders clear of the bunch by the 555m crest of the climb leaving a small peleton behind them followed by small groups of strung-out riders.

Descending the Rimutakas was a thrilling experience from inside the team car.  The riders who had been dropped on the climb were intent on catching the peleton and were descending with serious speed.  The road was closed to all traffic so riders (and team cars) were taking up the whole width of the road in an attempt to get down as quickly as possible.  It was absolutely awesome to see riders hitting 80kph down the twisty, traffic-free road.

Back on the flat and heading towards Martinbough most of the peleton was together with  Andy, Mike and Daniel all making the cut.  Chris and Jono had descended like mad-men but were unable to get back on and ended up in the large groupetto.

On the way along Longbush I saw one of the service vans behind one of my riders, Mike.  Mike had been nudged, touched wheels, and had gone down quite hard.  I jumped out of the car and took over from the neutral mechanic who was doing an atrocious job of trying to straighten his handlebars.  I quickly got the handlebars sorted, duct-taped Mike’s shoe to repair the broken strap, and jumped back in the car to pace him back into the race.  About a kilometer down the road, and doing 60kph behind the car, his back tyre flatted with enough of a pop that I could hear it from inside the car.  After a quick wheel replacement we were back at 60kph but not for long as the second big climb of the day started.  Mike was still a long way behind the peleton and he did an amazing job to ride himself back into the race over the next few kilometers.

Drapac Porsche were at it again with two of their riders setting a blistering pace up the climb and getting a lead of 30 seconds at the top.  The 90kph descent led to some rolling hills where the race needed to be stopped because of sheep on the road.  Only in New Zealand :-)

With the sheep cleared the race restarted and before long we passed the 20km to go kite.  Drapac riders Peter McDonald and Norris Lachlan were still clear of the bunch and were working well together until one of the final climbs which saw Lachlan return to the bunch.  McDonald’s lead was only 22 seconds by this point but he managed to time-trial the final 15km solo.  The bunch chased and lost a lot of riders in doing so, but couldnt catch him and Lachlan finished a few seconds clear.

All the boys finished safely – Andy was the highest finisher at 7 minutes back.  Mike crossed the line and announced that his frame was broken – apparently at 90kph down Limeworks hill it didn’t feel quite right and closer inspection showed two large cracks on his seatstay.

Back at the hotel, and with a spare bike for Mike found, I went about swapping his cranks, pedals, seatpost / seat and wheels across and gluing a new tubular to his wheel.  We got really lucky – the replacement bike was the same model Avanti Quantum in a 1.5cm smaller size so with a longer stem the fit and geometry will be very similar.

After a great rosoto for dinner (thanks Andy) the boys all hit the hay leaving me to rinse and fill the waterbottles for tomorrow and sit down with a glass of vino.

Stan’s Crest rims have arrived

Bryce from Cycletech dropped off three of the new 26″ Crest rims for a couple of builds: One pair for Jack’s Pro2 7 speed XC wheels and another for Helen’s upcoming rebuild.

The Crest is basically a new version of the 355 rim with Stan’s updated “Bead Socket Technology” – the external width is the same but the inner width is 2mm wider on the new rim.

Two of the rims were 346 grams, the other was 347 grams – claimed weight is 340 grams. I measured the ERD of all three rims at 543mm.

Raymonds DT Swiss 240s disc hubs laced to Alex R400 road rims

This is a cool pair of very light wheels for a ‘super commuter’ with disc brakes.

The hubs are DT Swiss 240s to accept Center lock disc rotors, the rims are the excellent Alex R400.  Spokes are DT Swiss Revolution and a combination of brass and aluminium spoke nipples.

Owen’s matt black fixie wheels

Some custom powdercoated Kinlin XR-270 rims in matt laced to polished track hubs with DT Swiss Competition spokes.

I love the look of the gloss black decal on top of the matt rim – reminds me of the Lew rims.

Rohloff spoke length chart

Here is a quick-reference chart for Rolhoff Speed Hub 14 spoke length.

These calcs will work with disc or non-disc hubs – remember that all Rohloffs are 32 hole and to be laced 2x both sides.

If you’re using spokes available in 2mm increments then round up to the next size, ie: if the chart suggests 261mm then round up to 262mm.

I’ve found that DT Swiss nipples work the best for the high exit angle caused by the Rohloffs large flanges and I generally avoid DT Swiss rims as I’ve found the eyelets restrict the rotation of the spoke nipple.

Rohloffs seem a bit intimidating to build at first but once you’ve done a few they’re actually very easy – the symmetrical flanges and large distance between spoke holes makes them easy to lace and the flange spacing builds into a pretty stiff rear wheel.

Chris King hub rebuild

I love rebuilding well-used high quality hubs – it’s evidence that good quality hubs can be used for a long, long time and will out-live rims which are damaged from crashes, potholes or brakepads.

These King hubs look to have done more than a few miles but the bearings are silky smooth and once the grime was wiped away they look pretty smart.

A new pair of A719 touring rims was fitted with 36 DT Swiss Competition double-butted spokes and brass nipples on each wheel – ready for another few 10 or 20 thousand kilometres….

Back in the workshop

I’m back from holiday and in the workshop.

I’ve got a couple of really cool wheelsets (like brown King road hubs with white / black spokes)  to build over the next few weeks so I’m excited to be back.

I didn’t do much riding while I was away but I did spend some time in one of these aqua-trikes :-D
