Swapped from standard 2x FSA Gossamer set-up to 1x with no hassle after heavy mud clogging.
A couple of muddy CX races after swapping & clogging not a problem.
Chain retention has been perfect.

Will this work as a replacement for a SRAM Rival 1 42T chainring?
05 Nov 2023
I am looking to change the gearing on my 1x11 gravel bike by changing the chainring from 42T to 34T. The Hope chainring is 110BCD and 5 arm, so should fit the Rival crank and another question confirms that there is no offset, but will this give the same chainline as the existing SRAM chainring? Also, will the existing bolts work with the Hope chainring? If not, i would be grateful for advice on what i would need, including any spacers that may be needed. Many thanks.
All your existing hardware should work with this chainring. SK 06/11/23
Thinking of going 1*8 with this
29 Dec 2022
I have an 8 speed CX bike with a 5 arm 50/34 compact chainring set up. I'm thinking of getting this 40T Hope single with chainring bolt spacers, derallieur extender and a 11-40T cassette. Would this work? and should I mount the chainring on the inside or outside of the arms (or whichever gives straightest line to the mid cassette?) Many thanks.
Ring choice will depend on the cranks you are using, provided the cranks use a 110BCD 5 arm pattern this will work, for mounting you can use narrower chain ring bolts designed to mount just one ring, I would use the line that places the chainring as close to the middle of the cassette as is possible.
Can i use this with a Shimano CX50 chainset please? If so which position please.
22 Jan 2021
We have not fitted this to the Shimano CX50 crankset to confirm compatibility. This chainring is designed to be used with x1 systems as it does not have any pins or ramps to aid with shifting.

Would this fit a FSA Gossamer 2013 crank on myCaadx

I want to switch to 1 x 10 and am looking for a suitable chain ring.
We are unable to confirm this as we do not have your crankset here to test this with.

Can I use this with shimano 105 5800 to chang it to a x1
09 Sep 2020
Hello- are you refering to a 105 5800 crankset? Hello, if not then no I'm afraid as the outermost chainring is offset so you could only use shimano offset chainrings.
1/8" chain
28 Dec 2019
Can I use this with 1/8" chain?
You can use 1/8" or 3/32nd but the 1/8 will void all benefit of the teeth shape and be a sloppier fit.

Could i use this with my 32 x 11 cassette
26 Nov 2019
I would like to drop front chainring 48/32 what should i get a 38t ot 40t and will this be ok with using old cassette 32 x 11
Yes, the cassette does not directly affect the size etc so this would be fine.

Thanks - 29/11/19
What is the offset chainline
30 Sep 2019
These are all straight with no offset, the chainline will be determined by the cranks/bb.

The transmission of my bicycle is: triple chainset Shimano Alivio (24/34/42) and a 7 speed cassette (11-28T).

I want to change the triple chainset for a single one, and I am thinking of installing the following combination:
– cranks: SJSC 110 PCD Alloy Single / Double Crankset 170mm
– chainring: Hope Retainer Ring 110mm BCD 5 Arm - Black, 38T

My doubts are:

– Is it advisable to change also the cassette and the rear derailleur?

– If so, I have thought about installing the "Shimano Acera CS-HG41 7 Speed Cassette" (it is the only one I have found with the 11-28T combination, that I like). And what rear derailleur and chain would be compatible with this set ?

Thank you very much in advance.
Going from a triple to a single without increasing the size of the cassette is going to massively reduce your range.

Yes that combination of cranks / chainring will be fine, just require some single ring bolts.

You only need to change the other items if the current ones are worn.

Do you sell the boss for the hidden bolt on the sram force cx 1

we do sell a Pack of 5 chainring spacers including the hidden bolt which is SJS Cycles part number : 49660.

Can I use this?
14 Jul 2019
Hi, is it possible that I could use this on a shimano dura ace 7900 as a single speed only chainring? I want to run a 44t chainring on a single speed set up. I have a single 17t shimano freewheel cog.


we never tried this ourselves so could not say for certain if it would work or not. If the BCDs match then it may possibly work.
Can I use this in a 1x8 setup?
16 Feb 2019
Yes this would be suitable for 8 speed.

Can I use this with Sram cx 1?

Can I use this with Sram Cx 1 1x11 group set.
