It's your ride

Today I'm changing the theme again, and linking to an excelent film sponsored by Hutchinson Tires. I think it conveys beautifully the freedom of riding a bicycle on a sunny day. Be sure to select HD mode.

Special Handlebars for MTB

Regarding handlebars, the only decision to be made when selecting them is usually the choice between flat or riser bar. These two types of handlebar dominate the market and are present in almost any mountain bike sold today.

However, there are some alternative choices that can be interesting for someone looking for a bit more of comfort or a different type of steering behavior. I've compiled a small list of handlebars that fit in this category. This list might be useful for somebody currently unsatisfied with their current handlebar and trying to find a perfect handlebar for their favorite type of riding.

Groovycycleworks Luv Handles


Handmade in Wooster Ohio by Rody Walter, these steel bars have a very interesting geometry, with 1 inch (25.4 mm) of rise and 21.5 degrees of sweep in the grip section. They fit quite well in the hand and show a very good balance between stiffness and comfort.

Clamp: 25.4 mm
Price: 85 USD
Weight: 315 g advertised, mine weighted 386 g

Groovycycleworks Luv Handles Ti

This is a titanium version of the steel Luv Handles. Lighter and obviously more expensive than the original.

Clamp: 25.4 mm

On-One Mary

From England comes the Mary bar, probably the most popular swept handlebar. It combines significant rise with gradual sweep. Due to aluminum construction it is relatively light and cheap.

On-One Mary Cro-Mo

This is a Cro-mo version of the Mary bar, intended for heavier riders.

European Cycling Online Shop List

This post lists some of the most important cycling online shops located inside Europe. I started doing this mainly as a future reference for myself, but I think this list might be useful for someone trying to find a special deal in some specific component as most of these shops have numerous sales and discounts.

The shops from which I have already bought are marked with "√". All other shops have some positive reference in cycling forums so they seem to be reliable.

Fixing what does not need to be fixed.

Ever since I've started riding singlespeed, I've been interested in trying off-road fixed gear riding. I was fascinated by the tales of crazy descents and

I even had an 18T Tomicog patiently awating in my desk for more than a year. But to ride fixed, first I needed a frame that didn't require external tensioners and a rear wheel combining disc mounts with v-brake ready rims. The first problem was solved with the sliding dropouts of my Explosif frame. The second problem was solved when a few months later I picked an SS specific wheel with the required hub and rims rims mount from an online sale.

The assembly was quick. Mount an old tyre, tighten 6 screws, retension the chain and recenter the rear brake. Off to the trails.


The first impression was shocking. I tought I had forgotten how to ride a bike, it pushed me up and down incessantly, placed my feet in the wrong places at the wrong times and didn't leave a single second for me to rest.

But I insisted. First slowly without clipless pedals to gain confidence. I learned to stop gradually with my feet, to control the position of the cranks using slides. With time, everything becomes more natural and the final result is a whole new level of control over the bike.

Climbing with fixed gear is also a really cool experience. There are no dead centers and the stroke becomes more fluid. Each climb is always taken in full attack position, there is no single moment of hesitation.


In the end of my third week riding a fixed bike, I was already descending (albeit somewhat slowly) really rough terrain, including a local DH track. Once you understand the basic rules it becomes natural.

I'll probably just use the fixed gear setup occasionaly, because it is a bit slower and more tiring. But whenever I feel like having real fun in a bike, I know that I can just mount a rear wheel and hit the trails.

My Kona Explosif 2008

After using a singlespeed bike assembled with old and budget parts for 6 months, I found myself completely convinced by the concept and decided to build a new bike, based in a dedicated singlespeed frame.

Some online research brought the 2008 Kona Explosif frame to my attention. A nice Cromoly steel frame, with sliding dropouts and well sorted geometry. I also had the luck to find it quite cheap in the wiggle.co.uk online shop. After some further comparison with the alternatives, I found no better deal and as such, a size 19 Explosif frame was delivered to me in July 2008. The frame is relatively heavy as mine weighted 2399 grams (5.3 pounds) with seatcollar and dropouts.


The final setup has changed a bit during the first six months after I received the frame. While I initially assembled it with some components from my previous build, slowly these components were traded for some high quality ones. The final result was this:


The bike rides very nicely and feels precise and quick in the trails. The frame ride is refined and has a distinct feel from the aluminum frame I had before. The custom made Amaro Ti fork was purposefully built with a very short axle-to-crown length (395mm) and large trail (45 mm), values typical of older rigid forks or cyclocross forks. The final result is a low front coupled with the extremely sharp steering due to the steep head angle.A Groovy Cycleworks Luv Handle provides a comfortable yet sporty riding position.

The light v-brakes XTR wheels are shod with large volume Schwalbe Nobby Nick 2.25 tyres. The tires combine with the titanium fork to provide reasonable shock absorption. While not comparable to an actual suspension fork, this setup is very usable and allows more than sufficient control to handle rocky terrain.


The drivetrain uses a XTR crankset converted to singlespeed with a lightweight Salsa 32t ring. The rear cog is a Surly 16t, a high quality component that has almost perfect finish and according to other users should last very long. The chain tension is easy to adjust using the sliding dropouts and I've not experienced any slippage problem that sometimes affects this kind of design. The only drawback with these dropouts is the reduced capability to hold a wheel with the skewers undone. If there is not enough tension in the skewers the wheel can jump out and jam in the frame.

Avid Single Digit 7 v-brakes were used in this ride to reduce cost, complexity, weight and simplify the maintenance. While not as consistent as discs for all-weather use,the power is more than enough and I've always had good experiences with the Avids.

The Explosif frame was discontinued for 2009, and replaced by the Unit 29er.
