Where There's A Will...

This week we’ve been looking at trailers for touring and commuting http://www.sevendaycyclist.com/tug-jobs.  Hopefully we’ll have some samples of Dani Foffa’s new urban clothing range in for testing very shortly. In the meantime, these 42mm Maxxis Roamer tyres arrived from another title and our Revolution ‘Cross test bike seemed the ideal candidate.

The Roamer is a wallet-friendly family of e-bike rated urban rubber, supposedly designed to cope with everything from commuting to touring. 60tpi semi slick casings, maximum 75psi operating pressure and a Kevlar breaker strip certainly indicate so.

Giving the ‘cross a visual once-over, I reckoned the roamer wouldn’t present any concerns clearance-wise and those portly, supple casings also implied a compliant, easy-to mount set...  welcome antidotes to the Bontrager several weeks’ back.

Well, I was nearly caught out on both fronts.

The first 65% slipped aboard the rims effortlessly and sans tools but it wasn’t long before I was close to agricultural language and guttural groaning more commonly associated with hospital labour wards. “Oooooh! Go-on, go-on!!!! You will! You will, you will!” probably wasn’t the sort of tea-time entertainment my neighbours hard bargained for either.

Order was restored with the retrieval of my magic tyre wand that had mysteriously escaped its hook and was hiding behind the chest freezer. Having dialed the Spyre’s barrel adjusters in to provide some slack, wheels were repatriated.

Clearance up front was good-pretty much what you’d expect on a modern disc braked ‘cross/adventure biased build but at the rear, you’d be lucky to slip the proverbial fag paper between casing and chain-stay bridge.

To my amazement, it didn’t clog following a ride or two on the wild side but something to check, especially on frames with vertical ends where there’s no leeway. Lighter than the OEM kenda, these have been delivering a magic carpet ride over the lumpy lanes and increasingly battle scarred main roads.

They’ve given the ‘Cross2 a perkier persona and rolling resistance is much les than I was expecting from rubber weighing over 700g apiece, although thanks in part to the widely spaced gearing, ride/handling still feels closer to that of a middleweight tourer than ‘crosser per se.

The other objective that evening was to continue getting it as filthy as possible since this fetching blue Zefal bike wash had also been sent my way…Bike washes provoke quite a bit of debate and most work to broadly similar science with comparable results.

Most solutions (aside from citrus based versions) are alkaline and employ non-ionic surfactants. These basically break down the grime on a molecular level; ensuring non/organic grot is easily flushed away and does not reattach itself during the washing/rinsing phases.  Aside from distinctive blue colouring, Zefal reckon theirs imparts a protective, dirt and dust repelling glossy film...Time and testing will reveal whether there’s any substance to these claims.

Working on the basis most knobblies become slicks when feed sufficient gloop, I decided it was time to revisit the bridle path featured on our facebook page https://www.facebook.com/Sevendaycyclistmagazine/videos to see how they’d behave.

Despite some initial skepticism, the Roamer’s comparatively supple casings literally glided through the gloop, taking thorns, flints in its stride. However, while the strip is comprehensive, its thinner at the shoulders... Given another seven miles or so, a sharp hard infiltrated the recessed, traction boosting, water channelling grooves. Just as I’d pulled up outside the house, its rear tyre let rip with a hearty hiss. Ruptured tube seam, so new tube and back to testing…

Elsewhere, the Univega now sports this Guee silicone bar wrap. Despite materials in common it’s proving quite different from the venerable Genetic flare http://www.sevendaycyclist.com/genetic-silicone-bar-wrap   in many respects, though most obviously, texture.

Price is a stumbling block for some people but compared with space age polymers commanding similar cash, the rubber’s natural tenacity means these don’t require backing adhesives, so aside from introducing fresh UPVC (electrical tape) they can be repeatedly rewound.

The Guee benefits from a little extra pre-stretch (especially when feeding the first few centimetres inside the bar end). Thankfully, it’s less susceptible to stretch marks/discoloration under tension, which is helpful since it’s less generous than the flare. (I had sufficient left over for the Holdsworth’s pursuit bars) Only time and miles will tell whether performance justifies the £7 price differential...
