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

Meltdowns & Recoveries















A much-publicised heatwave hit on Monday 17th July (although arguably crept in over the weekend) meaning that my dawn outings were mandatory if I wanted any saddle time. 35-36 degrees is very typical for many Mediterranean countries, and I've experienced 37 plus in more tropical climes, but the UK isn’t geared up for extremes. For good reasons, dogs were either walked at 5ish or not at all, to protect their feet from blistering, not to mention heat exhaustion.

 

Signs had cropped up, warning of loose chippings along the lanes but I reasoned, given the heat, folks weren’t going to be laying these, or indeed tarmac. There’s no statutory maximum legal temperature before people can cease, or decline to work, in the UK. Given the present trajectory, the current administration would simply revoke it- on their much publicised “bonfire” of legislation.  


I found some new bridlepath to explore, which also cemented my feelings regarding Ursula’s saddle change.  


The Super Corsa was an inspired move and as these outings confirmed, surprisingly agreeable sans asphalt, too. I was pleasantly surprised to discover tarmac hadn’t turned to treacle (although some farm vehicles had left their calling card). Even at these times, the temperature was rising fast-from 11 to 19 degrees within an hour, 19 and 26 degrees, on subsequent mornings. Tarmac’s top layer begins to assume a softer state at 51 degrees but allowing for other factors, possible when the air temperature hits 25 degrees.   


Acceleration brought surprisingly cool, moist breeze, which was welcome and encouraged a faster than usual tempo. The Kask Protone Icon helmet also came into its own, rushing cooling air through my scalp. However, an oppressive heat was certainly promising. A muntjac deer pulled alongside, barking in a crude challenge, so we hustled along, rivaling each other for half a mile, before it exited right, into the undergrowth. 


Depending on mood and conditions, I generally alternate between Ursula and fixed gear winter/trainer.  I tweaked the latter’s chain tension while checking the tyre pressures and this ultimately resulted in a switch to the Halo White Line Classic & Shutter Precision PD8 HALO CLASSIC RIM & SHUTTER PRECISION DYNOHUB DISC WHEEL BUILD (sevendaycyclist.com). This also coincided with the security skewer’s implosion. I was torquing it to 10nms, when it sheared. Thankfully, I had a lightweight Halo skewer, so just switched.   


I’d recently switched the fixed’s stem, returning to the Kinekt which employs a very progressive spring/elastomer configuration. However, as I recall from testing, even with the stiffest spring, there’s too much travel for my tastes, resulting in a disconcerting knocking on the rebound.


A quick email to Evan at Cirrus cycles KINEKT Active Suspension Seatpost and Stem – KINEKT Store (cirruscycles.com) advised they’d produced a stiffer, aftermarket option and were happy to send me one. I didn’t need a second invitation. I also wanted to avoid delays, given the potential customs nightmare, which is looming in October.  


What are you spaffing about, Stenning? Well, on the present trajectory, the old CHIEF system is due to be decommissioned at September’s close, replaced by a CDS system, which appears to have been rushed and full of bugs. At present, pretty much everything is being waved through (hence goods are arriving quicker) and ample potential for smuggling.  


August onwards is the most active point of trading, whereas it bottoms out, come January. The other question is whether traders believe the new system will be rolled out and will migrate accordingly. This also affects imports I.e., goods coming into the UK. Shortages of produce and materials, including foodstuffs, will mean higher prices and grave consequences for many.    


Ending on a happier note, Carbon Cycles has graciously agreed to send me a carbon fork (aluminium alloy steerer) for testing. It’s designed for 26-inch MTB, which is in theory, an excellent candidate for older mountain bikes reinvented as gravel builds and/or those looking to trim the fat. At 918g (uncut) it’s a good bit lighter than the otherwise loveable 4130 “school chair” Cro-Moly pair, resurrected with the disc brake upgrade and will serve as default spares.  


Carbon Cycles set a suggested rider weight limit of 97.5 kilos (215lbs), so no problems there. I will be putting some Helicopter tape around the legs (Zefal Skin Armor Roll ZEFAL SKIN ARMOR ROLL | cycling-not-racing (sevendaycyclist.com)  is a firm favourite of mine) to protect against cable tie bite and cable rub. Otherwise, no modifications, and I will continue to employ the Gusset Unilock, since it offers more security than the humble Star Fangled Nut.  Right, I'll leave you with my review of the Momum MIC Dry Momum Mic Dry Oil Lube | cycling-not-racing (sevendaycyclist.com)
