Wickens & Soderstrom No.8 sealant


SO GOOD
The yoghurt-like consistency and large particles make the W&S sealant handy for seating baggy tyres or fixing bigger holes, so long as you’re patient and keep feeding it in. It works best when mixed with a runnier sealant and inflated with a track pump to force it into the holes.

NO GOOD
The No.8 is so thick that it spreads itself thinly around the tyre instead of forming a pool at the bottom ready to fill any holes. It can’t always fix small punctures at normal riding pressures (30psi or lower) and sidewall punctures are virtually impossible to plug unless it’s mixed with a thinner sealant. It’s not cheap either.

Price 18$ for 300ml (=60$ for 1l)

SPECIALIZED P.STREET 2

S pecialized’s P.Series bikes have been much loved hardcore/ jump hybrid contenders for years and this 2014 nugget is no exception. If you’re after a really well priced and well sorted complete bike package for jump, street and even better-groomed trail centre action then the P.Street is outstanding. Its rock solid responsiveness and short-stroke fork make it seriously unforgiving on rougher trails though.
