You need to ream the HT deeper, carefully cut to length, ream deeper again and finally face it (with a standard 1 1/8" combined reamer-facing tool). So keep that in mind when you want to build your own conversion with my rear frame and front fork. The main frame is still original, except for shortening the headtube for a fork that fits 2.6" wide tyres. After that, I started building CroMo rear frames and forks myself in June 2019 (instead of modifying Brompton frame parts) and made them suitable for 18" and later even 20" wheels and 2.2" wide tyres. In any way, based on the bike you own and the specs of the Xplorer you want to build I can compile a kit that fits your needs.Īs you might have seen on my Instagram account it all started in February 2018 with modifying Brompton's own rear frames and forks to accept disc brakes and derailleur gears in normal 16" Bromptons, still a fairly narrow tyre. In case of a derailleur version you need some tensioning devices to take up all the chain when folding. And keep in mind that you might need some extra parts. For people who want to build an Xplorer themselves based on a Brompton of their own you can leave the main frame, stem and a few other parts out of the price of the Xplorer frame kit which saves you up to a maximum of €792.

For the time being I have enough stock of frameparts (main frame and stem) to build complete Xplorer bikes with, so no need to ship Bromptons from far away destinations to the Netherlands. I can offer Xplorer frame kits and complete bikes based on existing long wheel base (LWB) Bromptons (post 2010 preferably) or with a Brompton main frame and stem from my stock. The Xplorer bag on the other hand is readily available through the webshop I've got so much work ahead of me that it doesn't make sense to add more people to the list. Untill further notice the Xplorer order book is closed.
