Disc brakes for gravel bikes opened the door for more extreme off-road
adventures.
I have been gravel riding for over a decade, mainly on 23mm Conti 4 Seasons on my
rim-brake traditional-style bicycles during our summer cycling trips. Back in 2012, for
example, I rode the half-tarmac half-gravel Col de Portet in the Pyrenees.
The arrival of disc brakes, enabling wider tyres on racing and cross bikes, opened the
door for more extreme off-road adventures by taking one bike and two wheelsets instead
of taking multiple bikes on our summer adventures.
In 2015 I started my search for the perfect gravel bike (even though the term itself had
not been invented yet!). Eventually, I settled for the Niner BSB 9 RDO cyclocross frame
accommodating up to 40mm wide tyres. The choice for discs and also Di2 was already
confirmed after a few days on a rental disc Di2 bike on Gran Canaria. The frame has a
perfect fit for me as the geometry is almost exactly the same as my previous road bike
and it handles all conditions really well. The maiden gravel voyage in the 2016 summer
was the Colle delle Finestre and the epic Cresta dell’Assietta road, where I
surprisingly encountered very few mountain bikers.
The comfort and handling of a bike with wide tubeless tyres, disc brakes, and Di2 made
me sell all my old-school rim-brake bikes and get a second Niner. The first red/black
one is racier and the yellow/greenie is more suited for gravel.
High on the wishlist was a carbon deep rim set.
I want a carbon rim set specifically designed to accommodate wide tubeless tyres and
beating the windy flats around my place, but also able to take on the hills in the Eifel
(Germany) and Ardennes (Belgium).
Reading the Hambini pages the specs became very clear: external width of at least 30mm
(the rim should be wider than the tire), internal width of around 25mm, and a rim height
of 50-60mm, tubeless of course, perhaps even hookless. The only option in the
marketplace seemed to be one model of a well known but very, very expensive US brand. A
complete wheelset would cost even more than a new Niner frame!
Luckily some intensive internet research revealed Light Bicycle, and wherever I looked I
only found positive posts and reviews in many different forums. And yeeha! they had a
Falcon Pro rim, the
WR50, that
checked all the boxes. Finally, I could get my hands on an affordable top-spec aero
wheelset to complete my gravel racy flat-country Niner! The customer service was
friendly and quick to answer all my questions.
Hans van Leeuwen, from http://www.maatwielen.nl, is very familiar with Light Bicycle rims and suggested several custom specifications (e.g. internal nipple holes) for the rims. He made a perfect wheelset and laced the rims to a pair of DT240s hubs with stealthy silk graphic decals.
In the Luxemburg and French hills, the WR50s performed flawlessly.
As soon as the finished wheels arrived at my home, I was at first struck by the width of
the rims. They looked really, really wide! Perhaps even wider than a pair of my 29er MTB
wheels… Installing and mounting a pair of Schwalbe 28mm Pro Ones was as easy as tubeless
mounting can get, and the tyres popped airtight after pumping with an SKS floor pump.
Milk is only needed against punctures.
What a joy to ride. The wheels perform awesomely. In the flats, they seem to generate a
few kilometers of additional speed, especially in crosswinds. They feel light and nimble
when accelerating and climbing. In both Niners, with the signature Falcon Pro finish,
they look perfect. The sound is very polite and decent and does not draw unwanted
attention.
This year, despite the Covid-19 pandemic, we were extremely lucky and could still do our
usual 3-week cycling trip and visited Luxemburg (a few days), France (even fewer days),
and Italy (almost 2 weeks). In the Luxemburg and French hills, the
WR50s
performed flawlessly. Also, taking on serious alpine colls in the Italian Eastern
Dolomites was as easy as any climbing wheelset. Descending is drama free, even with some
gusty mountain winds.
For next year a gravel-specific wheelset based on hookless Falcon Pro
WR38 will
accompany the
WR50s on all
cycling trips. I can’t wait to order them!
