SRAM Rear Mechs (10sp) advice

So SRAM are new to me, only ever used GripShift SRT's before they became a conglomerate of other companies.

So looking at SRAM rear mechs they all seem way over priced compared to Shimano.

I just want a '10sp' rear mech but don't know the finikities of 10speed.

I'm going to run them with some 10sp gripshift hopefully for a commuter. Now I can see an Apex mech for a 'proper' price (£25). What else is there and will the 7/8 or 9 speed mechs be fine with the 10speed chains and shifting in SRAM world ?
 
Just bought an X7 for my Cooker as the X5 got bent. First time i've had SRAM too. Nicer quality than the X5 and went straight onto exisiting setup no problems. cheap too as new old stock. latest X7 is £52.

Just back from first ride with no issues.

Re:

Isn't Apex road? As far as I know, 10 speed shifters don't work with 7/8/9 as they pull different amounts of cable but couldn't say for sure if this would apply to an mtb shifter and road mech (But doubt it would work). However, there are some mods to be made but can't remember which way round it goes. It's a 6mm spacer in between housing and mech I think but don't know if that was a 9 speed mech and 10 speed shifter or vice versa.
 
Re:

Can't see why there would be a difference, just the index positioning. SRAM use there 1:1 and we'll 1:1 is 1:1 no matter what is pulling at one end and the other. Unless i'm missing something.

Doesn't matter at the moment as it turns out the shifter is a single not a pair as On-One implied in its advert. Who sells shifters singly, must be a modern thing. On-One acknowledged it though.
 
I think it's to do with how/where the cable goes into the mech for different leverage? As there is an integrated pulley. Pulley positioning is crucial. Hope I'm not making this up! Some new sram mechs use a redesigned rollamajig. 10 speed is naturally more narrow so would need to be different.
 
Most places sell shifters singly now, CRC and Wiggle have for 4 or 5 years.

And 1:1 is a marketing thing, not an engineering description. Can't remember which way round it is, and who does what, but it varies from nearly 1:1 all the way through to 1:1.2...........

You'll need to look for your specific shifter and find out what it's compatible with (that's straight forward enough, all 10speed SRAM MTB is the same).
You're unlikely to find you are the first to try, so some judicious googling should get you the answer.

EDIT: done my own googling, all 10 speed SRAM is cross compatible. 7/8/9 isn't.
 
Re:

Good find. 1x is so common now I wonder if they make batches of single shifters just for this
 
Re:

But it was front shifters they where selling and there where no rears for sale. Also it was 10sp compatible and marketed as 2x10 or a 3x10 choice and gave weight for the full set. I think they may have a few going back from people. Especially as RRP is something like 80 to 90 which is, to me, a full set price for griphift.

The ten is all indexed the same, works with Shimano cogs to. Cannot see why they would need to alter it from MTB to touring casual, to roadies hence just assumed (with a bit if research) they would be fine.
 
Single front shifters is a bit odd actually!
That's proper niche, i only know of a couple of riders who would need something like that for weight weenieism.
 
Re:

The 1:1 was a meaning of the pull at the shifter to the pull at the mech. For each index at the shifter it would oull the mech the same distance, hence griphift could work easier as all gaps between shifts where the same. So twisting should be more natural.

Shimano has a non linear pull, given the rear moves the same between cogs the front rapidly got shorter between each shift as you go up the numbers. So 1to2 maybe a 10degree[#] rotation and 7-8 only a 3degree rotation.
Easy to see on twistgrips, less easy to see on Rapidfire unless you open them up and look at the ratchet positions.
It may also be why Shimano might, if it has, changed its pull ratio as it will need improved acuraccy as it get to 11 and 12 speed shifts on it ratcheting.

#Rotation degree may be dramatised and not actual numbers, it is there for wiffywoffy science effect.
