Ringing the Changes










  

Having swapped the Mirage for the carbon with Middleburn and Campagnolo Record, I have saved 83g, which was less than I’d expected but saving grams wasn’t the primary, or indeed, original mission.  


Having bolted the rings together and snugging them down “blind” the first sticking point was discovering the Xenon did not employ self-extracting crank bolts, necessitating a quick root around for the crank puller. Not a hardship, but it was not where I’d expected to find it.  


I toyed with treating myself to a Park CCP-22 complete with integrated handle, since Holdsworth, Fixed Gear Winter/Trainer also use square taper cranks (although the Holdswoth’s Stronglight employ self-extracting bolts). However, by and large crank removal is rare and usually coincides with bottom bracket replacement (between 6,000 and 10,000 miles, depending on what fit n’ forget-sealed model I’d gone for).

  

Extractor found; the Xenon literally popped off their tapers-hardly surprising but welcome. A quick tug of the ACOR cartridge bottom bracket also ruled out any slop or grumbling. I might go for something lighter when these strike. Something with a carbon fibre spacer, alloy cups would save a few grams... Back to the crankset.   


Slid on the tapers, I found myself needing to raise the front Victory mech up a few millimetres and for some reason, it got the sulks. Nice new cranks, lovely new rings, what’s going on here???? I mused... 


Hmm, a new cable might sort things- costs pennies and I had a few in. Yup...the new cable sorted matters and the cage was swinging the Sachs chain snappily to and fro. I pruned the cable, leaving a little to subvert potential stretch overnight. Checking the Sachs chain while I was there confirmed it was in good health (although I had a KMC in stock, since these things usually expire at the least convenient moment).  


Continuing the weight saving, knee-friendly theme, I slipped some Peaty’s Bicycle Assembly Grease on the threads and whizzed Time ATAC in- the resin, rather than aluminium bodied versions. A quick once-over of the crank bolts and chain rings the following morning, shifting checked, I topped up the CST Cito CST Cito Folding Tyre | cycling-not-racing (sevendaycyclist.com) with the SKS Air-X-Plorer Digi Floor Pump 10.0 SKS Air-X-Plorer Digi Floor Pump | cycling-not-racing (sevendaycyclist.com) and popped it away ready for a shakedown ride the following morning.    


Wetter weather and the urge to explore green lanes and bridleways has meant Ursula and I have been out to play a fair bit, too. I’m warming to the Maxxis Ikon in these contexts. As I’d expect from a small block model, they’re less ponderous than a more aggressive trail tyre on metalled roads and come into their own along dry singletrack-plenty of smiles per mile. 

 

Despite being the baseline version, the ride is compliant and I’m yet to flat. Kenda Small Block 8 were quicker off the mark and a bit livelier but also more prone to flats. Elsewhere, I’ve gone for Muc Off Dry lube, which is keeping the chain clean and returning reasonable miles per application. It’s also been the ideal opportunity to see how the Madison Roam perform off road proper 


Time also allowed me to replace the fixed’s Stronglight in favour of the FSA Orbit MX. The latter’s stack height is a little taller-only by 5mm and easily solved by dropping a spacer. When it comes to headsets, stoicism is my default grease-wise. I want the stuff to say put, keep the bearings slick and corrosion-free. Now, the MX is also blessed with seals, which is nice. It’s another reason to avoid lithium or PTFE-based greases since these could cause perishing.  


Some lighter middleweight preps, including Muc-Off Bio Grease and Green Oil Eco grease hold their own surprisingly well, too TWELVE MONTH TEST: GREEN OIL ECO GREASE (sevendaycyclist.com) Flying in the face of this, I found myself pondering Peaty’s Speed Grease PEATY'S SPEED GREASE | cycling-not-racing (sevendaycyclist.com), for the last word in buttery smooth, friction busting lubrication. Ultimately, I’ve decided treating the bottom race with Juice Lubes Bearing Juice and the upper race with Peaty’s Speed Grease was the best compromise
