Shimano Warranty – 2 x bent Zee Mechs
Shimano did warranty a bunch of these early on as they had a really bad failure rate, never did see any concensus on why (I think it’s just what happens if you stick the bottom half of a saint mech on the top half of an SLX… Then release it into teh wild where it meets 1) people who’ve got the chain length wrong on their 1×10 and 2) people who think it’s as strong as Saint.)Posted 3 years ago
First one lasted 8 months, second one bent in three rides. Do I have to go through the seller?
Seems like the main metal body bends, cage and all other bits are fine, hardly any marks on either. I hit the clutch housing and its not pointing away from the bike. And before anyone asks, its not the hanger. lol.Posted 3 years agohonourablegeorgeMember
I had a Zee mech fail, the cage just came apart, on the first day, no impacts or weird chain lengths or anything. I beat it back into shape with a claw hammer, couldn’t get it shifting smoothly again, and dumped it ina box and replaced with Saint – same bike, chain length, the low, worked perfectly.
Six months later I sent it back for warranty, and they replaced it.Posted 3 years agoBoardinBobSubscriber
Bent my Zee mech with a really minor scuff on the side of a rut on its 3rd ride. Cage was fine but the mech was bent in the main body. Luckily the guys at the Shimano tent at the EWS replaced it free of charge after much begging due to the fact Alpine bikes weren’t stocking any rear mechs and the other bike shop in Peebles doesn’t open on a Sunday!Posted 3 years ago
3rd Zee mech bent, only slightly tweaked outwards but its killing my lower jockey wheel. Its clearly down to the chain growth so im going to change it to a medium cage.
Looking at the SLX it looks indential to my zee on the front and rear body parts. Should i not bother with this as i keep bending these and look at the different Deore or step up to XT?Posted 3 years agoNorthwindSubscriber
The top end of SLX is more or less the same as Zee (the front knuckle is Saint, for some reason). I reckon maybe the toughness of the old Saint cage is too much for the SLX top, something’s got to give… Could be wrong. Zee is definitely borderline for cage length on chaingrowthy bikes.
XT seems tough to me, yet to kill one and both mine are absolutely mauled. But maybe tomorrow I’ll destroy one.Posted 3 years agonever mind the butterMember
My medium XT has twisted it’s cage out, purely from the effect of chain-growth and the clutch. Chain is plenty long and it hasn’t ever been hit (most hits have the opposite effect anyway). LBS wrench says it’s common, as is the lower jockey wheel unseating it’s bearing causing the chain to contact the cage. All down to the clutch being too strong for the design of the mechanism.Posted 3 years ago
