I've searched on here but there is so much information and not all of it is a direct answer.

The rear shock on my NC30 is pretty tired. The spring seems way too soft even for my 10 stone frame! Rebound damping is also past its best. Adjuster on the shock body is seized. Way too much static sag plus rider sag but I don't see any point in adding preload when its probably knackered anyway.

So has anyone had their unit rebuild by Brook suspension who advertise on ebay? I'd like to know if this is the best option for the money involved. I don't have a massive budget so cant afford a Nitron unit or similar.

Another option seems to be another "modern" shock with HRC linkage but again sounds like it will cost quite a lot to do.

Also seen welding/re drilling the standard dog bones to effectively increase spring rate, Is this really a good mod or a bodge considering the NC has a flawed shock progression/geometry rate already? I could do this and have the unit rebuilt.

Thanks in advance

pretty sure Alex whitham had his done? A few have had it done...they all said it was OK.

You sure it was the correct side you're trying to adjust? Seen this a few times - the right side is not made to turn, adjustment is on the left hand side.

There are a few budget options out there (cbr, gsxr or s1000rr shock) but I think at the end of the day these are all bit of a compromise (even when resprung and revalved to suit the nc). One of these shocks combined with the hrc link is a good option, but IMO the money would be better spent on rebuilding the standard shock.

Getting your standard shock rebuilt (and resprung) by a reputable shock place is probably a better option, but will cost a little more than dropping in a shock from a different model. If your standard shock is tired then shortening the lower dogbone won't help things at all.

Most expensive and best performing option is a bespoke aftermarket shock (nitron, maxton, penske etc).

It all comes down to how much you're willing to spend, the value you place on the bike and what you need from it. The owner is the only one that can answer this.

I had mine done - it seemed a decent job. One thing that worried me was they fitted a bolt and copper washer to the back of the reservoir. I was expecting a gas valve or something similar, not sure if a copper washer would keep gas in long term. Of course I could be wrong and misunderstanding what was done. I plan to turn a new back with place for a proper gas valve next time I do one.

I had heard sometimes the shafts bend and wear so I sent 2 old shocks so they could build the best from both.

If there is no valve on it how did they put gas in it?

I have been trying to figure that out, mind you I want to know how showa do it
