1947 Ideale Model 65 Saddle

1947 “Hawk Nose” Ideale Model 65 with duralumin rails

Ideale Saddles were often a builder’s or rider’s choice on quality bicycles produced from the early 1900’s to nearly the end of the previous century.  The manufacturer,Tron and Berthet, began operations in France way back in 1890.  While they made many highly prized saddles, some of the most interesting lightweight models feature these large duralumin rails.  Together with the supplied duralumin clamp, these saddles were lighter weight than any competitors’ models, some weighing in at 250 grams less than a standard saddle.  This Ladies Model 65 weighs only 15 ounces, or 425 grams.  For comparison, the smaller standard Brooks B-17 weighs 540 grams.

It is a lovely saddle, having come equipped on my 1947 Camille Daudon, and was in nice condition for its 70 plus years of age.  While the leather was a bit dry, there was no cracking and the leather had not separated from the rivets anywhere on the saddle.  The seatpost is alloy also. I am guessing that the seatpost was custom made by Camille Daudon.  It has a closed top, is feather weight, and should polish up quite beautifully.

And so, I was looking forward to cleaning and polishing the beautiful alloy Daudon seatpost and Ideale seatpost clamp.  The entire Ideale clamp assembly is alloy, except for the axle and bolts, which are steel.

Even the round washers are alloy.  However, there is a down side to these lightweight components.  As you can see above, one of the alloy clamp pieces has broken apart and the other is cracked.  These seatpost clamps require a lot of torque to prevent the saddle from altering its position while cycling over bumps and other surface anomalies.  The alloy clamps probably could not withstand the torque needed to keep the saddle in place while riding.  That means sourcing some undamaged clamps to fit these wide duralumin rails.

Cycling around Canby, Oregon

Posted on by

If you are looking for a peaceful, nature-filled cycling adventure, look no further than Canby, Oregon.  The site of this little town was once a gathering place for Native Americans who enjoyed the local crop of strawberries and used the area as a meeting place.  Canby sits on a plateau above the east bank of the Willamette River.  The Canby Ferry, on the outskirts of the town, is one of those rare cable ferries, and will take you across the river on a tiny conveyance whose maximum load allows for 6 cars and 49 passengers, plus a bicycle or two.

Cycling around Canby is mostly flat, but if you venture out east of Highway 99E you will begin to climb up to another plateau that sits at the base of the Cascade Mountain Range.  For today’s ride, I stayed close to town, and was able to use mostly my highest gears.  In fact, as I was blasting away in my top gear I thought:  Uh oh!  What will it be like on the return trip?  As it turned out, I seemed to have a slightly downhill grade the whole way, and enjoyed spinning leisurely on my Meral.  Many of the town’s back roads have 25 mph speed limits.  I kind of worried about exceeding them!

The town’s website has several bike route maps which you can download.  I printed out all of them for my trip today, but actually ended up just riding where my instincts took me.  One route not to be missed is the Logging Road Trail which leads down to the river.  I took an inviting unmarked path off this trail and ended up at the banks of the Willamette River, after walking the bike through a very muddy section.  I was rewarded with a lovely view of the river, quietly meandering northward toward Portland.

On the way back, I encountered lovely pastures, crop fields at rest, and big horizons.  Seeing these irrigation wheels reminded me of my childhood.  My grandfather was an enthusiast of this “new” technology back in the 1950’s.  Wheel line irrigation is in use today, but was developed many decades earlier.

If you have the opportunity to cycle here, I think you will be delighted by the roads, friendly residents, and the enticing call of the wild.

A Meral for Town and Country

Posted on by

Bicycles with 650B wheels are nicely suited to a relaxed riding style.  The wider rims and greater clearances on the bike’s frame allow for plump, comfortable tires.  Often, vintage 650B bicycles are set up as city style bikes, with minimal gears and an upright position for the cyclist.

My recently acquired early 1980’s Meral randonneuse cried out for a 650B conversion.  It was built with Vitus 788 tubing around a set of narrow, 700c rims.  The bike as originally configured had a high bottom bracket and minimal tire clearances. These elements would normally indicate an ideal bicycle for a 650B conversion. Still, I wasn’t sure if I would be successful converting the bike, because the brake clearances were odd – with the front brake having less reach than the rear brake. In times past, competitive oriented bicycles were sometimes built with more brake reach in the rear than the front, and that was so that a shorter reach and therefore stronger brake could be used at the front end.

The rear brake reach on this bike is greater than the front by more than several millimeters.  When it came time to install the Mafac Raid long reach brakes, this fact made me concerned.  In order to have the rear Mafac Raid brake pads contact the new 650B rim, I needed to angle them down slightly, which is not ideal.  There are other options for dealing with brake reach problems, including installing brackets (a la Sheldon), and filing some material off of the caliper arms, to allow the brake pads to sit a bit lower.  None of those options appealed to me.

I decided to ignore the problem for now, as the front brake reach was perfect for the conversion to 650B, with plenty of room to position the brake pads correctly.  I am using Velo-Orange’s smooth post “squeal free” pads for this set up – and they are working perfectly and as advertised.  Since the front brake provides 70% of a bike’s stopping power, I haven’t noticed any issues involving the angled rear brake pads.  Meanwhile, here are some photos of the rest of the build:

Brooks leather grips, Tektro vintage style levers, V-O thumbies, Campagnolo shifter

Velocity A23 650B rims

Shimano Tiagra hubs

Meral custom steel fenders, wine cork spacers

Meral custom steel rack, with mounts for front flashlight.

This project was loads of fun, thanks to the beauty and quality of this vintage Meral bicycle.  The custom fenders and rack were a perfect match to its new Town and Country personality.  V-O’s thumbies worked well for this build – they can be used with just about any type of shifter so are more adaptable than their Paul’s competitor.

I used a lower end 650B wheelset that I will not purchase again, and I consider the wheels as a placeholder for now.  Probably I will build the ideal wheelset for this bike when the time comes, and will sort out the lighting options at that time.  Meanwhile, I hope you enjoy these photos of this amazing vintage bicycle which now has a new lease on life.  I have included the specs and full build list at the bottom of this post.

This gorgeous custom Meral steel rack can also be installed at the rear of the bike.
