IRD XC Pro Thumbshifters
The front is friction only, so front derailleur and chainset choice is wide open. The rear is indexed only. Since Shimano’s 9-speed road and MTB mechs use the same cable pull, that’s fine. The shifters are light (150g/pair) and durable. A hinged clamp with suitable spacers makes fitting easy, to flats or drops from 22.2-26mm diameter. Shifting is slick. I used them on a Genesis Longitude, the kind of bike they suit. UK distributor is fine-adc.com. Mine were from hubjub.co.uk, who are awaiting stock.
