I recommend this product
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.

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?

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.
