Forks, Spacers & A Bit of Faff

 









I decided to break fitting into two sessions. Primarily since there was quite a bit going on and am a subscriber to the measure thrice, cut once school of steerer tube pruning. After all, you can always lop a bit off, or add another spacer. You *can’t* add more fork steerer tube.(I know it is technically possible, but highly impractical, especially when it comes to aluminium alloy)   


Some will point out that you don’t need a dedicated cutting guide and, taken to its lowest common denominator this is also true. However, guides make life considerably easier and reduces the risk of potentially costly mishaps. However, a decent quality hacksaw, marker and steady hand are imperative. 


Preamble aside, having pruned the steerer to the desired length, I quit while ahead and started installation the following afternoon. I had been more conservative when cutting the steerer, so rounded up some additional spacers to compensate. Wheel removed, cable ties for mudguard (fenders), dynamo cabling and computer sensor snipped, it was time to perform the switch.  


The most complex part was juggling everything in situ (only to discover I needed to switch the spacers around). Blessing in disguise, it gave an opportunity to re-grease the Aheadset bearings (Last done six months back). Park Tool Polylube 1000 TESTED: PARK TOOL POLYLUBE 1000 LUBRICANT FOR BICYCLES (sevendaycyclist.com) to the rescue. Besides, I wanted to use the tube up, since it had burst along the seam.  


A quick lick to the Gusset Headlock’s threaded parts since I was there and shot of spray grease inside Ursula’s inner sanctum rounded things off nicely. Even doing the crude, juggle n’ lift comparison test, the new carbon set was palpably lighter than the very likeable 4130 Cro-Moly “school chair” pair.  


Everything together, pre-load set, I reintroduced the wheel and tethered cabling to the new fork leg and was just about to tether the mudguard (fender) stays when I noted a distinct lack of graceful curve. After some contemplation, it was clear that I’d need to trim the stays down a bit. I have chosen the cable tie route since this was discrete and yet stable arrangement.  


Topeak Versa mount are another alternative, although I’ve seen some riders employ “Banjo clips” commonly employed in plumbing and other applications. However, if you are going this route, regardless of fork material, make a shim from cut down inner tube to protect the finish.  

Admittedly, the mudguard’s curve isn’t as graceful as first hoped but stable and functional. I also switched this “universal” computer sensor magnet for a Cat-Eye unit. To some extent, one magnet is much the same as any other and in my experience, many have proven interchangeable. Sensors tend to be model specific, although, from time to time, I've got lucky when plundering the spares box. 

 

However, the profiles can be incompatible with some setups too thick and thus strike the disc calliper. Precisely the issue with my fixed gear winter trainer-hence the switch around. A stock of spacers always comes in handy. I’ve replenished supplies of these and some M5 bottle bolts since those belonging to my working bikes were past their prime.

 

I managed to restrain my “Child at Christmas” urges and resisted the temptation to nip out for a shakedown ride the following morning. Wanted to cast fresh eyes over everything first. Saturday came. A quick once over and I headed out for a 90-minute dawn meander.  

Formative impressions are favourable.  


Aside from a palpably lighter front end, they seem to provide a compliant ride over washboard tarmac. I pulled over at one point to tweak the Aheadset- an easy two-minute job-once I’d found my multi tool. Pondered 15mm spacer beneath the stem, for improved aesthetics and possibly tenure at that point. Went that route several days later and, famous last words, I won’t meddle with this arrangement

Foiled by The Fork









 I’ll attribute this to Storm Eunice and its slow-release offspring that caused a major dip (but thankfully not total) in household power. Cooker, microwave, PC, washing machine etc were inoperable, but broadband, lighting was still operating, and I could type and generally communicate, courtesy of the laptop. The kettle would also boil, albeit at a very pedestrian rate.  

Things to be thankful for and a taste of what might be to come, here in the UK… The present administration has been romanticised the 70’s era of three-day weeks, blackouts and similar indignities.  


Then, of course, there is uncertainty around oil and gas supplies, given Russia’s invasion of Ukraine.  


A situation that was inevitable, given Putin’s posturing and rhetoric but felt like a nightmarish simulation, rather than reality from this corner of the world. Speculation is a very dangerous thing and truth is the first casualty of war.  


The figures for casualties have differed wildly. However, if Vladimir Putin is genuinely looking to recreate the Soviet Union, I believe the military will head for Poland, rather than neighbouring Moldova or Romania. Once of course, Ukraine and its infrastructure has been obliterated. 


Regardless of route, this has grave humanitarian implications-civilian casualties, people left homeless and displaced. History repeats itself.   

This is a conflict I believe will last many years and may well prove to be another Afghanistan for Russia. Putin may have under-estimated Ukraine, in a similar fashion.  

Sanctions are on everyone’s lips, but for some, its little more than lip service.  


If Putin cut Europe’s supply of oil and gas, this will have some very real implications for Europe and the UK. However, this would leave Russia with the Chinese market and the Chinese could dictate prices on their terms and a take or leave basis. What is clear is that we have a humanitarian crisis, and some nations are stepping in to help, others are turning their backs.       


Anyhow, during this phase, I sketched out a plan of action re Ursula’s front end. Continuing my recent bite-sized theme, I decided I’d switch to the Project 2, lose the existing cable hanger and Ahead spacers for thinner fare, and stick with cantilevers. That was the theory, and it was materialising in practice too, until I discovered the Project two has forward facing dropouts, which would’ve precluded guard fitment, even with the adaptors.  


Then, to compound matters, the TRP calliper was sloppy- the mount’s threads were virtually bare-the perils of buying used and, moreover, blind. Lesson learned. Back to the Univega’s triple butted originals. Presented an ideal opportunity to pack the Stronglight Aheadset with lashings of Peaty’s Assembly grease PEATY'S BICYCLE ASSEMBLY GREASE | cycling-not-racing (sevendaycyclist.com). The name might imply it’s for contact points (carbon aside) but is a smooth, middleweight blend well suited to bearing surfaces too. Attempting to rescue something from the slightly abortive mission, I switched to the Shimano CX50 cantilevers, which in turn presented the opportunity to test some Capgo brake cables.  


The cables are stainless steel and the outer wires impregnated with PTFE to minimise friction. I don’t like the Shimano straddle wire system, so reclaimed the Tektro cable hanger and Transfil straddle wire, resulting in precisely the modulation and feel I like from a front stopper. 

The fixed gear winter trainer is also getting some decent miles in-nimble backroad blasting now the front stopper is behaving exactly as it should. I’ve raised the saddle by a centimetre and snugged tight with this M System Torque wrench.


By the roadside multi-tools are fine but these days components are built to very tight tolerances, so torque wrenches are up there with track pumps. I also have some interesting larger section 700c rubber headed my way. I’ll leave you with my review of the Torque Covert 7 Crank Multi Tool TORQUE COVERT 7 CRANK MULTI TOOL | cycling-not-racing (sevendaycyclist.com)
