Brompton rear triangle widening , custom gearing thread
Hi I want to start a thread around this subject to get a central thread and conclusion on fitting wider hubs to a brompton. Ie to use afline /nexus hubs or rear drailers.
I am going to outline my situation, but any information would be welcome to provide a comprehensive database of the possibilities. I want a thread to be informative and not just offer me solutions, but cover all aspects. Ie fitting 8 speed SA without widening triangle, rolhoff etc.
I am aware there is information elsewhere on the Web, but I have found it difficult to summarise the different approaches that people have taken. Ie cold setting, welding,cutting down hubs, altering chainline.
I am considering using a spare shimano Cespro rear hub on my sporty brommie (5 speed). I have a friend who is offering to remove the brake arm fron the rear triangle and replace with a slightly larger version using a mig welder. The frame would be widened to 135mm OLD to take a standard hub, he has also offered to put a drailer hanger on. 9 speed would go with road race STI levers my preferred option and be lighter than an IHG. I then may go for a Steven perry ish front mech option. I have a 56tooth front. I have not found much information about rear mechs and interference with folding.
Data base begin. No opinions, just facts LOL
Post your wisdom /links, ....etc here.....
