I recently purchased the H&H T-Line BCD 130 Spider and their 48T chainring to replace my factory 56T chainring. However, after phoning a couple of my local bike shops, it seemed like all of them had little to no experience working on Brompton T-Lines. So I was thinking maybe I'll suck it up and change the parts myself.
The official Brompton service video says I need an FSA E0667 tool to remove the spider from the crank. My question is, can I get this on eBay? I don't see many websites selling it in the US and most of the ones that do are from Europe. Also, can I use the same tool to install the H&H spider? Or do I need another FSA tool? H&H says it's an FSA mount. Also how many links from my chain do I need to get rid of to go from a 56T to a 48T? Is there a calculator or site I can use to do the calculations?
Many Thanks.
