Front Derailleur Destructor

Blast from the past post…

I’ve had two derailleurs on my Hilsen self destruct. The first on a 300k keeping me in the big ring for the 2nd half of the ride. The second on a commute home. Different manufacturers, same bike and crank/chainrings. Strangely, they both broke in August – exactly one year apart. The other strange thing here, I have the exact same crankset on my Vélo Routier, and have never had an issue. It uses an older derailleur – Suntour XC Pro, however.

I’ve gotten advice from “ignore it – probably just unlucky” to “need a stronger derailleur”. Something is going on here. I have always been careful to align the derailleur within 2-4mm of the outer chainring. Perhaps this bike just needs a 1×10? I’ve never had another bike destroy even one front derailleur, so I was suspicious of the following:

Chainring 16 tooth spacing (44t – 28t) too great a jump
Chainring thickness (chain seemed to stick to big chainring)
Derailleur construction

On to the specifics:

The first one let go on a 300k brevet on August 4th, 2013. It was a Shimano CX-70. Luckily it happened after my big climb for the trip up to Artist’s Point on Mt. Baker.

Popped on the outside

As you can see, the outer cage popped out at the top with a fairly clean break. To be fair, I had several instances of chainsuck over the prior year that spread the derailleur apart. To fix, I would just push the cage back into the normal shape after I re-railed the chain. I assume it finally fatigued to the point of failure after the last chainsuck.

I then mounted a Campagnolo Centaur CT that had worked well on other bikes. This lasted for approximately 1 year, but then self destructed in much the same way on August 12, 2014, breaking on the upper inside plate.

Popped on the inside

At this point, it was clear that the shifting pressure was too much for these modern derailleurs. I decided to swap the big ring from a 44t to a smaller 42t so the gap was not as great. With an inner ring of 28t, I dropped the spread from 16t to 14t with the hope that it would not be as much distance to push, however, the problem always happened when dropping the chain from the large ring to the small. I had an extra CX-70 that I put on this bike. It came from the Hunqapillar, which had never mis-shifted or chain-sucked while it was mounted.

A year and a half later, and all is well. No sign of problems with the new CX-70, and no further instances of chain-suck. I have a feeling it was the large chainring causing the problems. C’est la vie. One of the more frustrating things about biking (and food/diet) is the sparse amount of useful information out there. Anyone else had front derailleurs go boom on a road bike?

Ah, the simple days of not having to worry about shifts. Tech will get us there again, soon. Can’t wait for the variable ratio belt drive bike that you can control with your embedded chip.

New Toussaints

Our northern buddies at Cycles Toussaint in Calgary have introduced a new Vélo Routier. I took one out for a spin to see how it compared to my v1 bike.

V2 Vélo Routier

My first impression was that it felt just like my Vélo Routier. I’m not sure that I would be able to tell the difference in a blind test. It felt planted and quick steering. Comfortable, not quirky. This was set up similar to my own bike, with a Selle Anatomica, Noodles, bar-end shifting, and Compass tires. This geometry just works for me. Nice bike, great brakes. They offer the v2 in 2 versions – one with braze-ons, and one without. I really like the braze-on centerpulls and the quirky seat-stay pump mount, so that would be my choice. The blue color is a nice change, too. One new quirk – there is a slotted rear axle mount now, to better accommodate IGH or fixed/single gear hubs. While this opens up the bike to more options, it may make bikes with fenders tougher to change out a flat on, but there are ways around the problem.

Toussaint Pavé

The next bike is a demo that is a new direction for Toussaint. I believe this is an all-round road/gravel, maybe even cross bike. It was set up racier than I would typically ride, but it was surprising in a number of ways. The tubing is all stainless steel, which gives it a fairly “ti” look. The downtube is quite oversized, as well, at 38.1mm. This seems overly stiff for my weight range, but can be offset with cushy tires. It is spec’d to take a 45mm fender, so I would assume you could put the Compass Barlow Pass tires on with no problems. It looks like a Clement MSO would fit fine for a bit more bite.

Toussaint used interesting plated fork and seat stay crowns. I like the classic low fork bend of the Routier more. To my eyes, it would be a great match for the double plate crown on this bike. The “banana” bend just looks odd to me. I assume it makes the disc attachment easier/stiffer, but if the bike could use a more classic bend here, it would be prettier.

Double Plate Crown

Disks make it a great utility rain bike. I found the bike to be quite like the Vélo Routier in feel – even with a bit more trail on the Pavé (45mm). It still felt quick steering, and was light and fun to ride. I was wondering how it would be with some front or rear load. I may see if I can get an extended trial to find out.

Seat Stays

After the ride, I am hopeful this bike would fall into a similar price range as the Vélo Routier – if you could get a bike built for the rainy NW commute, not have to worry about rust or wet brakes, and still maintain great geometry that would handle randonneuring or lightly loaded gravel adventure rides – nirvana, right there!

The Toussaint blog (with lots of good info on the tubing, geometry, etc…) is saying they hope to sell these for around $2000, so I guess the tubing makes a big difference, but we’ll see what happens if they do a production run. This is a cool, practical bike!

Soft Shoes on the Hardpack

One of the biggest dilemmas for me this year was the choice of shoes/pedals for the Oregon Outback. I have had great luck with clip-less pedals and Sidi cycling shoes, so going with flats felt like a big risk. I knew that we wouldn’t go more than 100 miles in any one day, but we would be doing it for 4-6 days straight.

On the other hand, I didn’t relish the thought of running around in cleats on rough ground for the better part of a week. They add a certain amount discomfort: slippery footing in some situations, and “duck walking” on the ground. They also introduce unnecessary complexity and technical failure risk if a cleat gets damaged, or a shoe gets lost.

On flat pedals, at least I could comfortably use sandals or bare feet (in a pinch).

I rode on flats for the most part all winter and spring before the ride, with a max distance of about 50 miles. No problems. I have had occasional knee pain that has developed in the past over longer miles, but I was not as worried about it in this case. Both my clip-less setup (SpeedPlay Frogs, Sidi Spider SRS) and flats give my knees plenty of float. I seem to have had the most pain on a relatively locked in SPD setup.

Long story short – flat pedals were great, thin approach shoes were comfy as hell.

About the setup I used:

Pedals: Watch your shins on these pedals – they are grabby and have sharp edges, but after a few nicks, you figure out how to stay away from them. They lock your foot in really well – there were quite a few “holy crap” bumpy, loose, fast downhills we had to traverse, and I never lost my foot on the pedal – something that has happened to me on other pedal/shoe combos, and scary when you are rocketing downhill on single track or loose fire roads. These guys just work, and have a large platform to find purchase on.

Shoes: I’ve got 3 pairs of these – they are the most comfy shoes out-of-the-box I’ve yet encountered. They are a minimalist approach shoe, but are runnable. They wear well – I still use all three pairs, and two pairs have gone on several off-road adventures. Oh yeah – they are fairly inexpensive, too…

I also used some Echo sandals for part of the day when we were in the hotter, more exposed sections of the trail, but I mainly went this route because I had gotten the Cruzers wet, and wanted to dry them out on the back of my bag. This is an added benefit of flats – spare footwear just works.

After several days on the dusty trails, my feet felt great – no pains or aches, and my knees were fine for the distance. I hope other folks try out this sort of combo – the cycling community still really pushes clip-less combos for “comfort”. While some may need an extra stiff sole, I think this may have evolved due to the tiny surface area on most clip-less pedals. Try some big, flat pedals – you may be surprised…

That’s it for now. Let me know if you have found similar flat pedal/shoe combos you like.

Getting back on the blog. It’s been a long hiatus since my last post on June 11th?? Wow – I feel lazy. What’s been going on since May/June? I guess I’ve been low-key biking, working, and occasionally kayaking. No big bike trips this summer. The closest thing has been a brief bike around Amsterdam in October, but I’ve literally done zero rando events this year. Ironic as it was a PBP year. Well – there will be others. I’ve still got a few stories to get out, such as:

What worked on the Oregon Outback
How is that Velo Routier doing these days?
What about the Homer and the Hunqa??
Food and clothing thoughts
Soma (old brand) single speed conversion (maybe)

OK – got that out of my system.

Oregon Outback 2015 – Day 3

09 Tuesday Jun 2015

Crooked River, Deschutes National Forest, Fort Rock, Gravel Touring, Hammock camping, hammocks, Oregon Outback, Prineville Reservoir, tuff ring

-Endless

Day 3 started out with the epic straight flat road common in areas wealthy in sheer space. We rode into the tiny town of Fort Rock realizing we had missed our chance at a party the night before. Lots of bikers were camped out behind the bar and in the patio. We filled our water reservoirs and bottles, and carried on past the Tuff Ring that is Fort Rock. This was formed 50-100 thousand years ago when a 150-foot-deep lake filled the basin and an upswell of magma hit the mud and water of the lake bottom. The area looked a lot like what I would imagine of a drained sea, with the scrub brush like a floor of coral and seaweed. It reminded me of areas of southern New Mexico – vast concave landform.

– Yours Truly

We gradually climbed out of the Fort Rock Valley ascending into the Deschutes National Forest. Trees were still sparse, but we were getting back into the pines. The smell – if they only bottled it! This was the first sunny day, so it was a warm ride. It would require most of our water on this stretch – I don’t recall a refill until we reached our destination.

– Looking Thirsty

The third day is supposed to be tough, and I felt it. After the dry forestland, we meandered across more sparse brushy vistas. At mile-57, we started an amazing descent down into Sage Hollow. For the next 10 miles we followed Bear Creek and speeds were in the 20+ mph range. Not many photos on this day – too much good riding to do.

At the bottom was a beautiful, green ranch with a paved road, but there was one wicked climb up around Taylor Butte. This was in the heat of the afternoon, and no cooling wind was helping us out – it felt like we were pedaling in an oven. We only went up 800 ft in 2.5 miles, but it was brutal granny-gear crawling with the loaded bikes. We felt our destination nearing as we reached the top, and after a nice descent, we reached the Prineville Reservoir.

– Water

– Crooked River Cliffs

After a short hop across the dam, we made good time down the paved road along the Crooked River, and arrived at our favorite campsite of the trip: Big Bend. I had a nice rinse in the cold water of the river, and washed a few items. Lots of folks were fly fishing up and downstream. This was the height of the Memorial Day weekend, but there were still plenty of campsites open. Remote areas don’t get much business even in these heady dayz.

Our water had lasted around 70 miles – one of the longer dry stretches. That said, there were several places we could have begged water along the way if things were worse.

– Camp. Picnic!
