Replacing the rails on a Brooks Flyer saddle

A couple of weeks ago I rode through a pothole on my bike, there was a loud bang and I was suddenly a lot closer to the pedals.  The rails on my beloved Brooks Flyer saddle had cracked!

On closer inspection the rails were bent as well as cracked, just in front of where the seat post clamp was positioned.  Googling found plenty of examples of this happening to Brooks rails but mostly with the saddle all the way back on the rails rather than all the way forward (which puts the rider weight more directly over the seat post).  Given the cost of the saddle, I wanted to try and repair it.  I purchased replacement rails and today settled down to repair my saddle.

What you need:

  • The “Flyer bracket and coil assembly” (BYB299)¬†which I got from SJS Cycles. ¬†You can purchase direct form Brooks but I found that shipping was cheaper, especially as I was ordering other things from SJS anyway. ¬†It might be possible to order the rails separately and reuse your existing springs but I thought I may as well replace the whole lot. ¬†If you buy just the rails, the instructions below will still work but you will need to undo the nuts that hold the rails to the springs rather than the springs to the saddle.
  • A 1/2″ spanner
  • A Brooks tension spanner
  • Some time to do the job. ¬†This took me about ¬†45 minutes with a few interruptions so it can probably be done in under 30 minutes.

To replace the rails:

  1. Remove the saddle from the bike.  This is obvious, I know, but you may wish to mark the seat post bracket position for tilt with a marker so you can put the saddle back in the correct position easily.  Work on the saddle upside down.
  2. Loosen the tension pin fully.  I am not sure if this is 100% necessary but it looked like it was and seemed to make the later steps easier.  Take note of how much tension is in the saddle before releasing it so that it can be re-tensioned afterwards.

  3. Using a 1/2″ spanner undo the nuts where the the coils¬†join the saddle. ¬†The nuts are hard to get at and required some creative angles with the spanner.
  4. Once the nuts are removed, lift up the bracket and coil assembly and flip it 180 degrees so that it is nose-to-nose with the saddle.

  5. Lift the bracket and coil assembly, tension pin and tension shackle out of the saddle.  Keep them all together.

  6. Place the replacement assembly next to the old one and move the tension pin and tension shackle across to the new assembly.  Make sure that the pin and shackle are in the same position on the new assembly.
  7. Replace the new assembly, tension pin and tension shackle nose-to-nose with the saddle and flip it into the saddle, slotting the coils onto the bolts.
  8. Replace the nuts on the bolts and tighten them.  Again, this requires creative use of the spanner.  It is nearly impossible to avoid scratching the coils with the spanner (at least with mine) but try to avoid it.  The bolts should be tight but not too tight or they will start to dig into the coating on the coils.
  9. Re-tension the saddle to the tension as above.  My saddle seemed a little under tension after this step so I added a little more.  It is possible that that was a contributing factor in the breakage to begin with.
  10. Replace the saddle on the seat post in the correct position.
  11. Go for a ride and check everything feels OK.
  12. After a few rides, check that the bolts are not loosening.

Ride to the garden centre with the iGo Two

I took the iGo Two out for another trial today.  I rode it up to the local garden centre with the two girls on board.  As expected, it was pretty slow but fun and not difficult to tow at all.  The girls loved it again.  Hannah was comfortable enough that she fell asleep on the way home!

WeeHoo iGo Two 2015

For a while now, I have been toying with the idea of getting a bike trailer for my daughters so that we can go out as a family on our bikes or, more to my wife’s taste, I can take the girls out so she can have some time to herself!

I had looked at the Croozer Kid for 2 online as well as looking at my colleague’s single version. ¬†It looked to be the right balance of price and features. ¬†Tempted as I was to go out and get one, my wife sensibly suggested we try a friends’ double child trailer first. ¬†So, I found myself on a chilly January morning pedalling off with two girls loaded into our friends’ Thule Chariot Cougar 2.

As soon as I set off, there were giggles from the trailer and it quickly became clear that the girls were having a great time behind me.  It was the first time I had ever towed a trailer with my bike and I was having to concentrate hard to avoid dropping the wheels of the trailer into potholes or clipping kerbs due to the extra width and length.  We were out for about 30 minutes and by the time I got back, the girls were almost asleep.  The verdict was that towing them in a trailer was a goer but that I was not sure I wanted the extra width.  Also, the best bike rides near us are mostly on unsurfaced tracks so I wanted something that I could take on those rides.

While looking at trailer reviews on the net, I discovered the WeeHoo iGo Two 2015.  It is a type of recumbent tag-along that attaches to the seat post of the towing bicycle rather than to the rear axle.  The WeeHoo website and YouTube have some encouraging videos of the single version of the iGo being used for easy single track mountain biking and on trails so it should be OK on the gentle off-road trails we have near us.  I showed the videos to my older daughter and she was very excited.  She loved the idea of being able to pedal and being able to see all around her.  Having her little sister in the seat behind appealed too.  After daughter and wife approval, I was allowed to go ahead and purchase the iGo Two.

The iGo Two arrived in a large box and was cleverly packed inside to avoid wasting space. After checking the box contents, I set about the task of assembling them into an iGo Two. There are instructional videos on YouTube but the included pictorial instructions were easy to follow. Some parts were quite a tight fit, requiring some hand strength, but they were parts that should be tight. Only three tools were required: a 4 mm allen key (for seat assembly), a 14 mm spanner (for attaching the pedals) and a half-inch spanner (for attaching the rear footrest).

Once assembled, we hooked the iGo Two up to my bike. Fitting the hitch requires you to remove the seat post from the seat tube so measure your saddle height before removing it so you can put it back correctly. The hitch is a solid piece of cast aluminium which rotates around a plastic bush. The plastic bush comes in seven different diameters to fit different seat posts.  The hitch looks sturdy and, as with most trailers and tag-alongs, you can get extra hitches to fit to all your bikes.

Once the iGo Two was hitched up, we helped the girls into their seats to adjust the seat positions, rear footrest position and harnesses. ¬†Each seat has a three-point harness that holds the children securely in their seats. ¬†There are also foot straps to keep the front passenger’s feet on the pedals and the rear passenger’s feet on the footrest. ¬†This is great as it stops little feet going down towards the ground when you are travelling along, something that could be quite dangerous. ¬†Other safety features include handles for the passengers to grip and the ubiquitous safety flag fitted to all trailers. ¬†We found that the girls naturally gripped the handles when riding and the flag does what it should do and increases visibility.

Once the trailer was set up, I took the girls for a few spins around the block despite the cold.  They loved it and came back giggling and smiling (or perhaps their faces were frozen into a grimace).

We even got them to wave for the videos:

After our younger daughter went for a nap, I went out for about 30 minutes with our older daughter on her own on the iGo Two. ¬†When we got back, she couldn’t stop smiling!¬†We had a great time and I cannot wait for more outings with the girls and my wife.

All in all, the WeeHoo iGo Two is an excellent trailer for our needs.  It seems sturdy and well built, rolls well and is great fun.  So far, we give it ten out of ten.
