Overall Product Rating 5 / 5

Prosworks very well

I ordered this to go on a Peugot Le Mans that was salvaged from the tip 25 years ago, sold to a friend and returned in January ready for the tip again. Sadly, the original Huret derailleur had been replaced by a big, black Shimano MTB one. This looks much better and just about maintains tension across 52-34 front rings and a Sunrace 14-28 freewheel.

Questions & Answers (8)

Would this rear mech be OK for a triple chainset on a road bike

By Rich

02 Feb 2021

chainrings are 52/42/30, and rear rear cassette 11-28T

SJS Customer Service:

Thank you for your enquiry, no this item would not be suitable for a triple

Thanks: WD 02/02/2021

Will this cope with a total chain wrap of 28T, i.e. 13-25 rear and 34/50 front (12 16=28)?

By Richard

SJS Customer Service:

Yes, this will be fine.

Cassette size

By Dave Clayton

15 Mar 2019

Hello, you said in a previous Q&A that this mech would only reach 28T because it's a short cage. Is it purely down to taking up the chain slack? In which case would it make 32T if there was only a single chainset up front?

SJS Customer Service:

This is due to the physical position of the upper jockey wheel, with a single, this may suit a 32t better, but we would say its likely not to work .

Thanks - 18/03/19

What is the maximum tooth capacity please?

By Sean

09 Sep 2018

SJS Customer Service:

28t would be the largest as its a short cage.

Thanks

Is this compatible with an indexing system?

SJS Customer Service:

Hi,

As the spacing between the gears is the same on 5, 6, 7 and 8spd cassettes/freewheels you should be fine to use this derailleur with only 5 gears. You will need to make sure you adjust the limit screws correctly though to prevent you from being able to over shift it off of the cassette.

Thanks.

Can I Use With A 7 Speed Cassette?
