replaced mine a while back now.the pattern parts i bought were as good as origanal,side by side it was hard to tell them apart,these rubbers are very thick,mine were cracked badly and were like it for years before i finally got round to changing them,but once off the bike i could see the cracks were not all the way through....by a long way...if you have the same problem and the cracks are not that bad i would`nt bover changing them.
i think i still have the old ones in the garage,i see if i can find them tommorow and post a piccy

One, is never going to be enough.....
think one on out side is through as get bubbles when u put liquid over cracks :'( but have put silicone over them for time being
The new ones will likely crack as well, had you not wrote that there's bubbles coming out then i would say leave them but since you know there's a breach then fair enough, just don't panic when the new ones start looking like they've had someone attack them with a sharp hatchet
Smell ones mother. Yaas!
ok...sounds as if you need new ones.....i will see if i can find out where i bought mine and how much they were....pretty sure somewhere near £75...will let you know
One, is never going to be enough.....

WWW.MAD4BIKES.CO.UK and paid £78.98 inc p+p.....hope this helps
