Can this front derailleur be used to give my ICE Trike recumbent?
By
01 May 2020
…The trike has 9 speed transmission and I hope to get an old school 1/2 step plus granny set up? If not... can the SJSC team please suggest a possible alternative modern changer? ( I have a half step set up on a 1980's Dawes Atlantis 7 speed - using a deers head non indexed front mech - which I've used for many years ...with input from Chris Juden's writings...
https://forum.cyclinguk.org/viewtopic.php?t=19025)
My reasoning on the trike is that as I can't stand up in the pedals on a recumbent, I need half step gearing on my Sunrace 11-40T 9 speed transmission… Front chainset is 160mm cranks with 44 (or 42)/38/24 rings...I also race the trike with in BHPC events using a Sram 11-28T cassette... and the 1/2 step set up would really help the subtle gear changes for my cadence challenges - I have underlying health issues which are driving my line of enquiry. Can you please help? Thank you.
sorry, 1/2 step was a thing in the 1980's it has fallen from favour and I don't believe ANY modern front mechs can achieve this, you only hope is second hand or NOS on eBay RT
