Henrik Y Posted January 22, 2008 Report Share Posted January 22, 2008 I have an old hope mini disk brake and I was thinking about getting a new caliper and was thinking about the mono trial but there are a few second hand M4 avaliable so I was wondering how the M4 is compared to the mono trial. Or can I just forget using an M4 for trials riding? Quote Link to comment Share on other sites More sharing options...
matt rushton Posted January 22, 2008 Report Share Posted January 22, 2008 Mono trials will be alot better for trials. M4 has two 5mm (I think) pistons they may be 10mm. But trial brake has one 25mm one. Quote Link to comment Share on other sites More sharing options...
_Owen. Posted January 22, 2008 Report Share Posted January 22, 2008 The m4 might be ok mate, but it will have more modulation than a mono trial! The mono trial being made for trials, has less modulation and more bite! You might get away with using an m4, but id go for the trial any day of the week.

Henrik Y Posted January 22, 2008 Author Report Share Posted January 22, 2008 How is this one: http://www.chainreactioncycles.com/Models.aspx?ModelID=17249 compared to the mono trial? Quote Link to comment Share on other sites More sharing options...

Waynio Posted January 22, 2008 Report Share Posted January 22, 2008 get a trial one, it sort of gives it away in the title its designed for a purpose. it has all the power needed. with the mini and M4 i just find it doesnt give you as much confidence or power that the mono trial offers.Dont be shy and just get a hope trial caliper Mono M4 is made up of 2x 5/6mm pistons and 2x 8/10mm pistons i think. the pistons are 2 different sizes, you can tell this from the "bore" caps as one is usually smaller than the other. something like that anyway.Wayne.

Henrik Y Posted January 22, 2008 Author Report Share Posted January 22, 2008 I was just wondering because I've found 2 cheep second hand M4 but I haven't even found anywhere to buy only the caliper to the mono trial. So maybe directly from Hope or like chainreaction.com?Any ideas of where to get one? Quote Link to comment Share on other sites More sharing options...
