Robust stuff
Great quality and great service - 5 stars

SRAM GX Eagle 12 Speed Rear Derailleur off of trade me
Very smooth happy with it. Great that it was in stock and had prompt delivery. Much better than previous experiences on cheaper options. Will be purchasing again!

Great Upgrade from NX
Upgraded from the NX that came on the bike. Shifts are slightly quicker and snappier. Noticeable on pinch climbs and those roots where you need to drop a gear and then return to you pace.

Pulled through when no one else could.
Needed a rear derailleur and couldn't find one until i got in touch with Push Bikes. i had been in limbo for 8 weeks with other suppliers just to be told it would be another 6 weeks until i could get one. Push bikes pulled through with what i needed and i had it within a couple of days and now I'm back on track. Fast to respond with my online query and delivery. Very thankful.
