I’m not the sort of person to go riding without the basics that will allow me to fix a flat tyre. Bit of a security blanket I suppose, even though Bromptons are ideally placed to be folded & carried home in any form of public transport, if the Brompton (or me) runs into trouble.
My idea of the basics is a spare tube, tyre levers & pump. With most Bromptons having bolt-on wheels, a wheel spanner also needs to be included. The conundrum is where to carry everything & my C bag has been my place of storage (along with my water bottle). Now that my Bromptons are equipped with bidon cages, I decided to prepare for a “bag-less” ride & carry the tools on-board.
Brompton have produced a neat little toolkit that fits into the front section of the main frame but so far in the few months since release, I’ve been unable to obtain one – & now I believe they’ve been withdrawn to address a “quality issue”? My alternative is to rubber-band a cut-down wheel spanner, tyre levers & a small set of Allen keys together & wrap them in a set of disposable latex gloves. This fits cosily into the front section of the main frame.
A spare Schwalbe SV4 tube (Presta valve type) fits into the rear section of the main frame. My method of insertion is to double the tube over, lightly twist it into a spiral & then wrap this with a piece of fibreglass insect screen mesh (about 45cm by 20cm). This mesh “tube” then slides into the frame with far less friction than the tube alone. The length of the mesh fills the tube space & is easy to pull out.
The Brompton Zefal pump is fitted to the rear frame of one Brompton with a Velcro strap (hopefully) giving extra security. My other Brompton has a small pocket pump (Bontrager Air Pocket) fitted into the seatpost tube & secured by the seatpost buffer. (The pump is fitted into a length of inner tube (cut from an old Mountain bike tube) to prevent it from rattling.)
I’ve always been wary of the Brompton pump staying in place & preferred to carry the pump in the C bag. Now with my Bromptons carrying their tools on-board, I’m trying the Brompton pump attached to the rear frame but for peace of mind, will probably soon use pumps housed within the seatpost tube on both Bromptons.
