Payloads & Playtimes


 







When it comes to racks, four point and 20 plus kilo carrying capacities are my defaults. I’d tried and indeed tested beam types in the past but found they had a tendency not to manage the loads promised very effectively. However, the last was over a decade ago and the river of technology moves at an incredibly rapid rate.  

Not everyone can or wants a rack “permanently” mounted and they add scope for longer day rides and trunk bags, provided you had sufficient exposed seat post. Carbon seat posts remain non-starters. Frankly, I wouldn’t tether anything heavier than a wedge pack and rear light to a carbon, or composite post. This Topeak RX Beam Rack coincided with my interest in Topeak’s RX Trunk Bag DXP, which is aimed at road, rather than trail audience.

Made from heat treated 6061 aluminium alloy, it tips the scales at a surprisingly stout 665g and in any colour you like, so long as its silver. Beefy welds have an industrial beauty, rather than refinement but are neatly executed and inspire confidence.  The collar is relatively shallow, requiring less exposed post and somewhat reminiscent of an Ahead stem, courtesy of the twin bolt closure. This promises more reliable tenure than the in my viewed, flawed quick release closures.

Complete with shim, this supposedly means a universal fit-at least on round models between 25.4 and 31.8mm. In practice, I’ve needed to brew my own using redundant butyl tube, but that’s the thing with the phrase universal, it’s always begging for contradiction.

You’ll not I’ve given the fasteners a liberal helping of grease-in this instance   Oxford Mint Assembly Grease Oxford Mint Assembly Grease | cycling-not-racing since its very stoical and I had it to hand. Torque to 8nm.  

The maximum payload is 15lbs, which is modest, but practical for day riding, and, with careful calculation, gives scope for a fairly stout lock. As for the RX Trunk Bag DXP, this is made from 600 Denier Polyester complete with a DuPont Teflon Coating claimed to offer improved weather resistance.

The main compartment features “aerodynamic” foam walls and coupled with the drop down-side panniers and expandable main compartments equates to 7.1 litres- very useful for day rides and those who want more carrying capacity than a wedge pack but without the bulk and indeed wind resistance of traditional panniers.  I’ve managed to slip a decent amount into the main compartment-three spare tubes, tool caddy, spare tyre levers, Pedro’s Trixie, separate multi tool, cable ties and a patch kit.  

I was curious as to whether the Trunk Bag would also prove compatible with the marques Uni Super Tourist DX top plate. Spoiler alert, I was pleasantly surprised to discover it was, so left it mounted to Ursula for a few wintry outings.  Interestingly, the MTX Dry Bag Trunk Bag doesn’t seem compatible with the RX Beam Rack.  Rounding off this impromptu mid-afternoon fettling session came bottle cage replacement, I liked the contrast of the composite cages, which worked better in practice than I’d expected. However, they were prone to collecting grime, so I went for some black Elite Cruissi homages.

As for Ursula, my hunch that the trailer quick release would provide greater rigidity at the frame ends, eradicating any disc tickling under load proved correct.  Sometimes it’s those little victories that give the biggest lifts.

 I’m also pleased with Muffin’s Selcof Sterrato V2 bar switch, although they’re slightly narrower than the Genetic D Riser 4 they replace, but there’s still ample control and no skittishness. From an aesthetic perspective, it makes mounting lights and other little gizmos, such as this ORP Smart Horn that bit easier. I also suspected I would miss a left dummy lever for parking my hand when cruising. Some Dia Compe 138 with colour-coordinating black hoods turned up. I’m planning to pop the Cane Creek on the Holdsworth (since that runs a Tektro and the mutually compatible hood shape means everything will align nicely with the spirit level). Ha!      

Leatt have sent me their Pro Clip 6.0 Endurance shoes, which they say are “designed for riders who want dependable performance and all-day comfort without the race-focused stiffness”. Formative outings suggest they’re onto something here.

There’s a roomy toe-box, which is supportive and roomy enough for waterproof socks-a good move, since there’s acres of cooling mesh-essential for the warmer months given the synthetic uppers. The MOZ/Leatt lacing system will be intuitive to anyone familiar with the Boa types and allows for great, hassle-free tunability.

A Nylon shank is designed to offer the right blend of stiffness and support while allowing easy, comfortable walking or running sans bike. The ride grip outsole is suitably aggressive and grippy. They’re not as stiff as the Shimano RX6 Shimano SH RX600 Gravel Cycling Shoes | cycling-not-racing (and a little heavier too at 790g for the 45) , which remain a firm favourite of mine, but stiffer than Shimano’s MT701 GTX   Shimano MT701 GTX SPD Shoes | cycling-not-racing . Goldilocks but without the bears? Time, roads and boggy wet trails will tell.   Meantime, I’ll leave you with my review of the Castelli Unlimited Rain Jacket Castelli Unlimited Rain Jacket | cycling-not-racing and perhaps more fittingly,.
