2022 Unfondo Overhauling of White Lines


After I was promoted from the wait list into the 100 chosen for the 2022 BBC Unfondo Ride, it became necessary to practice road riding. In the process, its clear there has been some deferred maintenance going on with the primary road bike of the fleet, my Ridley Fenix Disc, nicknamed White Lines.

The efforts worked, White Lines survived the ride but some final tweaks went in even today (see bottom of list)


New Bell!

Given how much I enjoy and use the bells on the mountain bikes, I decided it was time to get one for the road bike. Installation was a bit tricky, I settled on an aero position that seems really loud, at least for me.

Front Derailleur Tune Up & Discovery

The lesson here is to RFTM - I watched You Tube video to discover an entirely new adjustment bolt I did not know existed on the Ultegra 8100.


The video warns of deltas from the 10 speed fronts and high tension required - I wish I had this 5 or 6 years ago when I installed this.


Tires - Finally Installed

I bought the Conti 5000 Whitewalls from Vlad, but they really are Tan-Walls. I used one on the front of the Solo Velo, but decided it was time to get them onto the intended target, White Lines. See the theme?

White Wall Tires That Are Tan



Anyway, slight disaster using an old leaky tube last week, the tires worked great this week and for the Unfondo itself yesterday.


Big Mouth Bike Rack Install on Tesla

Finally put the Mom n Dad Racks to use. Scheduled to take a 3rd in our carpool, I needed
another rail. It took a lot of work dealing with the T-Bolt install and it was hard to center and reach the middle position, but it worked. And didn't get used.

Racked Up, Backwards





Hint when using T-Bolts - just detach them from the levers, THEN put them into the rail.


Dura Ace 9100 11sp Rear Derailler, New Cable

This is the second time the Ultegra 11sp rear derailleur has been a problem - earlier I blew this unit up running a too short chain and then crossing it, while hammering up a hill. I got replacement cages and pulleys via Ebay


and it seemed good, but during front tuning, I noticed a popping effect as the lower pulley seemed to over-grip the chain. The cage is supposed to be slightly twisted, but more was going on here:

Rear angle of Ultegra Rear Derailluer Pulleys - whats with the gap in the plates?

Given the tight timing to the Unfondo ride, I did not have much time to get a replacement when I decided it was indeed the lower pulley position. It turns out Diamond Dave had a little Dura Ace 11sp sitting around and was able to let it go for a good price and perfect just-in-timing.


The cable here is always a trick,


provided a good starting point accept I went and upshifted the lever with the old cable already removed.
How to get it back? After poking and failing, I found the shift lever hood rubber blocking the motion of the tension release. Another annoyance is the cable covering/routing in the Ridley, its a light plastic that got knotted on itself, requiring me to cut n splice. 

The result is smooth, clean dura-ace shifting! Some tension adjustment is ongoing as the new cable settles.

Post Ride

The biggest issue on the ride was an increasing "creaking" noise - initially it was just under power, echoing through the carbon rim and disturbing neighbors in the paceline, until the end of the 75 mile ride where it was driving us all nuts all the time. In the last 5 miles, and after a quick attempt to adjust the derailleur tension one last time, I realized it was THE BEARINGS. Duh. The wheel did seem tight
vs other times I went to fix the bearings.

Steps

  1. tube n tire off
  2. remove disc rotor
  3. remove gear cassette
  4. remove axle ends
  5. remove cassette carrier
  6. tap out axle and non-drive bearing
  7. tap out drive-side bearing with a 19mm socket
  8. grease and place new bearings in place
  9. 21mm tap and hammer to drive side, 19 mm tap to non-drive side
  10. oil up the carrier end and MAKE SURE THE SEAL IS IN RIGHT
  11. replace axle ends
  12. locktite on bolts and re-install the disk
  13. install the cassette on the carrier, tighten lock ring tight
  14. tube, tire with starch as a baby powder replacement
  15. air, quick release axle and lever
  16. install wheel, test and tune

Cleaning of the Cassette

After removal from the D712SB hub, its time to clean the cassette Another t-shirt, some degreaser and elbow grease, its nice and clean. Not shiny, I think because its only Ultegra.

New Bearings For Rear Wheel

Checking my order history on Ebay and in my email, I buy a lot of bearings, last time in Jan 2021. So I checked the shed Hubs bin and found a pair of fresh bearings awaiting an adventure!


I checked a quick You Tube to make sure a hammer was indeed needed




and punched the old units out, greased them up and punched them back in - the socket sizes were
a good idea, I used a 21mm socket to get them into the drive side (used a 19mm for the non-drive as prescribed in the video.

Starching of Tubes n Tires

I finally ran out of baby powder, likely better for my health anyway. SO I grabbed some corn starch, nearly as lubricating to the rubber interfaces. I used starch re-installing the rear-tube, and even took off the front tire and tube to starch it up too.

Radio is talking about critical mass - I used to do that. Started Sept 1992, I was 1997.

Back to it.

Quick Test

Worked great, the Coospo computer however was not seeing the speed sensor. Did I knock it? Worked fine for the ride itself, some readjusting and it picked up speed again.

2022-0923 Fall Roundup

 Documenting Updates to the Fleet

  • Intense Shipped the Dropper Replacement!
    • I shipped the bad one back. 
    • I noticed no obvious air port to top off pressure. 
    • No news on what might have been the cause of the end failure yet. 
    • Installed the dropper and took it for a KT ride, worked fine as before.
  • Rockshox 35mm lower kit arrived for maintenance, but I need oil and desire to get dirty
    • Also got a 140mm shaft - I need to inspect and see if/why I am running so little pressure - maybe bent shaft? or dry/not enough oil?
    • IF oil works, return shaft
  • Need to return the Nukeproof XL pads - even the L seem big, very bulky. Okay with the elbows but the knees seem to be too much.
  • Unfondo - got pulled in from the wait list so I am in. Maintenance/tuning on Whitelines continues
    • new Coospoo is working well
    • got a bell!
    • tuned the front derailluer - I was doing it wrong forever apparently, but it still rubs in biggest gear
    • get new tubes and maybe install the GP 5000's on the intended bike?
  • Offering up Old Blue and FM166 to a young rider in need - has me pondering also adding White Lines and even Red Pinarello.
    • Noticing the shift in generations out on the road
    • Feeling old this am, not into the CX at all, even to practice after donuts today
      • Terrible feeling that if I lose riding, I lose my social life.

2022-0904 Popped the Dropper on Hi-Ho Silver (Intense951 XC)

 I set out to do a lap or 2 of Tamarancho this am before the heat set in. Took the race-configured Intense951 XC, and the new Nukeproof Enduro pads up the hill, thinking how well this bicycle was working - shifting, seatpost and brakes (mostly) have been awesome.

Rear brake under pedaling load and turning left chirped a little, I tried loosening the caliper bolts, then riding a bit and then tightened the result. Helped.

Anyway, sweating it out and keeping the HR under 145, Julian of the KT gang shows up while I hung out atop the Flow Trail. Julian was "going slow" which for him is a strong medium for me - still unable to hang on the downs. Did a lap and Una Mas'd another, when out of the blue past the "bell bridge", my seatpost went "POP" and my butt slammed down to the minimal position. Hmm, so much for the trouble free post. I assumed a chamber literally popped in there, no air,etc. but it seemed to move a bit too much. Struggled on out with lots of standing, and/or sitting low, ate a sandwich and Root Beer with Julian then went home with the broken rig.

Hosed it off, loosened the seat post and got a very long silver post and threaded end


That was unexpected. The whole scene:


I was able to thread it back in, but the cable was bent on the end AND broken at the lever - had not noticed that.

Looking into the tube, how was I supposed to get the cable back into the end?


Unable to find details on internal dropper cable routing for the Intense 951 or snipers, I went to the website and tried "chat". No US listings available but NZ and AU were selectable. So I hit it, and Josh G kindly answered from the AU option (NZ had no response, but maybe closed - 3pm in AU)






Josh's description of how it SHOULD be working gave me confidence that that threaded end had indeed been piston-ing into the seatube and warping the cable housing into a coil - from the phone and bike flashlights it looked hot-glue-gunned in place.

So a sharp hook on a clothes hanger and a little fishing I hooked the coil, pulled the cable straight, and was then able to pull out the housing as Josh promised. Hurray!



I need to buy an over-length housing and cut to fit. IF the seatpost works, no harm no foul. I did find some nice seatpost manuals with greasing and assembly instructions that might get put to use.


(458 miles on Hi Ho Silver according to the Strava Gear report)

2022-0824 Maintenance Log - new computer, new derailluer

 Received the $40 "Coospo" GPS/Ant+ Cycling computer, learned to program it, synced up Wahoo TickR HR and Garmin Cadence/Speed Ant sensor. Seems fine so far, BUT most notable observation is the device is physically HUGE, like 4x the size of a Garmin 500. Hilarious. Readablity looks good, I hope the backlight will turn itself off in the dark.


Task 2 was installation of a new Shimano 12speed MT8100? rear derailleur. I was bummed that the device looks exactly like the one its replacing, I hope the internals are improved. New casing and cable too, of course.

Headset Spacer Swap another -80g

 Not sure if this one was worth it, bit swapped a stack of aluminum spacers for some bigger carbon options in 2 pieces.

213g stack of Aluminum rings


134g 2 piece carbon spacers

Good ride at China Camp, I took Santa Creme with the WTB i27s from HiHo, now tubeless. I also put an Old minion on the front.

Rode okay, did notice the weight of the rear. First half was crap riding on my part, second part I clicked in. Shortish ride looking at the stats, used flats. Not sure if too much racin or not enough trailing.

Going to get spacers to put the big Light Bicycle rims back on the SC. Leaves me a spare front intense not fitting the 100mm pike. Never shoulda sold the spare fox 34 boost…

327 - 186 = 141g less thank you Niner RDO bar

 I need to turn off the scale backlight


327g Intense stock 760mm Al bar

186g Niner RDO 760mm Carbon bar

The Niner bar is a little flatter, so if it feels yucky might put on the SC Nukeproof bars. The height of the Meta bars are a good 100mm higher than the Intense...
