Sorry, boring question.
I have an SLX triple and was thinking of loosing the big ring & going double up front with bash.
I have an ISCG05 mount on the frame.
I’ve been looking at the E-Thirteen DRS for £100ish.
Any other thoughts.
Cheers.

Once for the evening crowd?

this probably?

blackspire stinger.

Stinger is good- simple and effective. Bit overbuilt- I had to cut away about half the backing plate to get it to fit my old frame and it’s still more than strong enough.

Gamuts dual ring thing is absolutely lovely to look at and weighs nothing but seems a little delicate.

But best option is to buy nothing til you know if you need it. Most people using doubles don’t have chain devices- after all you don’t use one with a triple.

That’s great help, cheers guys.
😀

If you descend in the “middle” (now outer) ring, the bash and derailler help keep the chain in place. Esp. if your chain is shortened so the derailler is tensioned, you may find it never drops. Or at least only drops onto the inner ring and slips back onto the “Middle” ring when you pedal.

You lose nothing by trying it. But if you do drop the chain then buy the stinger.

Stingers are cheap and cheerful but bend easily if you batter them on things. The roller is also pants – stick an MRP one on. DRS is much hardier, but heavier and lots more £££. Not tried the Gamut.

As far as bashes go. Do you tend to knock teeth off/bend your big ring? If not, go for one of the light weight ones like the Blackspire Ring God Lite, the Raceface Light or a Gamut plastic jobby.

Running a blackspire stinger with a C4 bash on my SX no problems in the 2 months it’s been on. 😀

If you ever find that your chain has bent links after a ride, then you need a chain device. The stinger is more that adequate and is only £22 from CRC.

superstar do this

but the reviews on their site don’t recommend it!

Some frames, like my Reign, have very low chain stays which can make fitting of a Chain device almost impossible.

the rollers on the stinger will last well over a year if sprayed with GT85 after every ride and they are available as a seperate part for a few quid anyway.

I run this as a bash

and this as a chain catcher

light and works. Haven’t dropped a chain yet – nowhere for it to go!

Cheers.
I’ve been knocking teeth off the big ring that I rarely use anyway.
Think I’ll go blackspire dewlie or e-13 DRS.

+1 for just getting a bash and then seeing if you need a chain device after riding for a bit.

Works out cheaper that way too.
