Two rings good...











Given that I haven’t gone the mullet route (at least, not since 1989/90 and I’m not admitting to that) with Ursula’s drivetrain, switching to the Maxxis Ikon has meant much more dirt in our diet and more time spent on the Deore’s inner (26tooth) ring-especially exploring green lanes.  

Though not unduly heavy at 714g (about 1.57 lb.) apiece by my scales, they’re a little heavier than the Maxxis cited as 592g (about 1.31 lb.) and present palpably more resistance on tarmac, compared with Kenda Small Block Eight DTC.  


However, it’s worth noting that the Kenda features 120tpi casings and can be run at 80psi, while the Ikon is 65psi tops. These factors mean greater use of the front mech and more frequent shifting generally. No, this is not the precursor to a triple crankset. Aside from anything else, three rings tend to be a chore to keep on song, four seasons round. 

 

Back to the Ikon...Hit firm bridlepath or green lane and the transformation’s instant. Oodles of traction and a very sprightly, magic carpet ride. Our first foray came during the bank holiday weekend when I was less time taxed than usual. I was having a general, 5am meander along deserted lanes, forming some first thoughts about their tarmac manners when 9 miles out, I spotted a fabulous example of green lane and chucked a left.  


A little caution is needed, since these things aren’t always accurately signposted, resulting in a detour through someone’s back garden. This happened to me while putting a cyclo cross bike through its paces at 3am one December day in 2007.  


Hurtling along a gently reclining slope, my euphoric bubble was pricked by the sight of two wheelie bins. A smart about-turn and pacey retreat followed. I was reminded of this some 500 metres along when I happened upon a cottage with cars out front. My gut and some hoof prints told me to carry on 


I laughed and attacked the swooping single track, pleasantly connected to nature and surprised by how well the Ikon bit into softer (but not soggy) surfaces. Since we’re talking tyres and trails, here’s the link to my review of the Topeak Gravel 2 Stage Mini Pump Topeak Gravel 2 Stage Mini Pump | cycling-not-racing (sevendaycyclist.com)  

  

Curiously, I’ve managed to wear a hole in the inner right thigh section of these Triban Men’s Road Cycling Bib Tights RC500, which might be a bit of a mouthful, but budget models that I’m particularly fond of. Being a test pair, I’ll have to put it down to experience (otherwise, had I bought them, I could’ve taken the warrantee route).


This photo also served to remind me my legs needed a good shave, especially since it's milder and I’m getting more miles in, on the Teenage Dream. Now, I continue to be impressed by the CST Cito and learned some interesting facts from their UK distributor. Much to my surprise, they’re designed for a maximum payload of 70kilos-which means, me and the operating pressures range from a very modest, mini pump achievable 80, right up to the cited120psi. Was expecting 90-120 if I’m honest but nice to know they can be run a little lower.  


After several weeks reprieve, the rains returned, albeit in passing. This resulted in derv and other light, slippery spillages being flushed from the verges and mixing with bovine dung and similarly slippery organic stuff. I happened to be sweeping into an S bend on the fixed. 

 

There was a momentary loss of traction from the front Maxxis Refuse but sufficient feedback bought me time to get things gracefully under control again. This appears an isolated incident-in more typically showery and rainy contexts, they’ve not missed a beat, allowing me to concentrate on a steady, 90rpm tempo. Again, their sweet spot seems relatively low at 65psi, but they can be run at 50, if conditions dictate.   


Thursday morning at 4am, fuelled by a constant flow of adrenaline. I was midway round the loop when I suddenly became conscious of resistance, spiking a rush of catastrophising, convinced the rear Re Fuse had done the unthinkable. Thankfully it hadn’t but the sense of urgency had me fighting for breath, but my legs felt surprisingly fresh, cranking out 100rpm until I arrived home.  


 Elsewhere, I’ve decided to stock up on KMC Z1X chains- this time with the silver finish. These feature the marque’s EcoProTeQ Coating (EPT) Anti-Rust technology, which also promises smooth and silent running. I’ve found the blue versions perfectly serviceable but lacking in outright refinement. Aside from dependable rubber, chains, and sprockets are not something I’d want to skimp on, when it comes to fixed gear builds, since there’s a lot of loading on these components.  


I’m not suggesting paying boutique prices. I also recognise the value of beveled sprockets for achieving accurate chain lines on conversions. There are other ways round this. Halo Fix G HALO FIX G TRACK HUB | Seven Day Cyclist Tourin Tests Commuting employs spacers to achieve this and I’ve even seen an eccentric bottom bracket, like those employed on tandems. However, I’m highly unlikely to go the eccentric route given I’m happy with the fixed gear winter trainer’s Genetic Tibia GENETIC TIBIA TRACK CRANKS & RING | cycling-not-racing (sevendaycyclist.com) and the Holdsworth’s Stronglight Track 2000.

Gravel a Gimmick? I beg to differ













 Some commentators suggest that Gravel is a gimmick. Sure, I don’t subscribe to all its nuances, but lightweight drop bar builds with the ability to traverse unmade roads have been cemented in my psyche, since 1986. I suddenly found myself contemplating another bar switch, this time to some On-One Midge. A flared design that I was initially sceptical about but stealthily grew on me, back in 2005 However, I quickly recalled that these Soma Fabrications Condor 2 SOMA CONDOR 2 SHALLOW DROP BARS | (sevendaycyclist.com) shape was great for the fixed and optimal for Ursula. 

Gravel clothing also lends itself very nicely to other genres- touring and indeed everyday riding thanks to its rugged materials. I’ve switched from my defaults, the Shimano RX600 Shimano SH RX600 Gravel Cycling Shoes | cycling-not-racing (sevendaycyclist.com) back to their more compliant, less racy MT701 GTX Shimano MT701 GTX SPD Shoes | cycling-not-racing (sevendaycyclist.com)


Primarily since I’ve stubbed my toe and the GTX are a little roomier at the toe box. Soles are more compliant, so lack the RX600’s razor-sharp power transfer but still offer excellent support and are a little more comfortable sans bike.  


A good bet for touring, commuting and general riding. If you’re on a relatively tight budget, FLR Rexton Touring/Trail shoe FLR REXSTON ACTIVE TOURING/TRAIL SHOE | cycling-not-racing (sevendaycyclist.com) are another rugged, versatile choice. Laces and Velcro lack the refinement and convenience of the boa systems and the emphasis is more on the lighter side of trail/gravel duties. However, they’ve stood up to wintry roads and other, not-so-balmy weather very well.     


Arguably, Polaris Bikewear’s discontinued Challenge range stole a march on this mixed terrain clothing narrative. POLARIS CHALLENGE NEXUS SHORTS TEST AND REVIEW (sevendaycyclist.com)  POLARIS TRAVERSE MEN'S JERSEY REVIEW (sevendaycyclist.com) not forgetting the Pioneer jacket, POLARIS CHALLENGE PIONEER WINDPROOF JACKET REVIEW (sevendaycyclist.com) I still wear these during spring and summer months.  


Pearson Cycles Adventure range and specifically, their red adventure long sleeve Cycling Jacket is my new favourite. It’s a bridge garment, in the jersey cum jacket vein. Reckoned to withstand a fast-paced encounter with a Hawthorne hedge, there’s a great blend of retro and modern.  


The main fabric is 65% recycled polyester, 25% recycled Coolmax and 10% LycraThe chest panel is overlain with Millerain. There are two deep breast pockets and a further two at the rear. One big poacher type for generic capture-all, the other for a mini pump. 


Gravel helmets also bridge the gap between genres very nicely. Bell Muni Urban Sport Helmet was another, now-dropped design ahead of the trend. Peak, 21 vents and LED lights at the rear ensured it performed well on and off road, touring and commuting. It also blended nicely with road and mtb threads and didn’t look out of place on a road-biased touring lorry, either.  


Looking at the current catalogue, the Bell Trace LED helmet looks the closest comparator. Madison Cycles Madison.co.uk – The UK’s largest cycle parts & accessories distributor sent me this Lazer Chameleon, which is another design intended to cross between gravel, touring, commuting and light trail dutiesOurs is the medium, which tips the scales at a respectable 283g and is the “lowlier” non-MIPS version (£20 cheaper).  


It features a crash replacement program, meaning a replacement can be bought at a discount, which hopefully you’ll never need. The Advanced Rollsys adjustment system is designed for a precise fit- crucial if a helmet is to do its job effectively. Rather than the big thumbwheel, there’s a smaller, splined dial at the top, and the cradle system avoids pressure points, while ensuring a clear, unhindered exit for ponytails.  


A peak, 13 large vents continue the versatile narrative. Ours is the two-tone matt blue, but there are other matt colours- black, white and red. Matt colours require a little more care and dedicated “polishes” but nothing outlandish, in my experience. Finish and specification are pretty much what I’ve come to expect from this end of the market.  


The polycarbonate shell doesn’t extend around the rim, leaving it slightly more vulnerable to the usual everyday carelessness but no more so than similar designs. In common with the Bell models, it is designed to accept a dedicated (aftermarket) light, but I’ve also found several others, including the Magicshine Seemee (100, 180 and 200-lumen models) a perfectly good fit, ditto the slightly heavier and now discontinued Xeccon Mars 60 TESTED: XECCON MARS 60 COB REAR LIGHT (sevendaycyclist.com)   


Thirteen vents might not sound particularly airy but thus far, they’ve been gulping in a decent and continuous flow of cooling air, without the painful “ice cream” headaches that can strike on long, fast, chill descents. Wind noise is also reassuringly absent and I’m forming a fondness for it-as if you couldn’t tellSame goes for Ursula’s new 2x10 Deore setup...
