Do brooks saddles take much looking after, how do they cope with wet commutes etc?
a bit #1. you buy some stuff called proofhide and apply it according to ancient lore
once a day for a week
once a week for a month
once a month for a year
once a year for life
a bit #2. Like leather shoes (think Doc Martins) the saddle needs to be broken in. Some people claim this is an agonisingly painful process which takes 1000's of miles. I suggest these people are riding saddles that don't fit them. Every Brooks model will not suit ever human r's. Mine are broken in, once and for all, after about 7 hours on board but are no more uncomfortable than any other unfamiliar new saddle during that period.
a bit #3. wet commutes, so long as you have a rear mudguard and stay sat on the saddle you should be ok. If honking is your thing then get a brooks or a carradice saddle cover.
a bit #4. my mtb saddle (B17N) has an under saddle water deflector made from an old washing up liquid bottle and the underside of the leather has been slathered with proofhide just in case my crudguard gets bashed out of the way and it ends up in the firing line. On a road bike with no rear mudguard you'd need to do similar.
a bit#5. you may need to tweak it over a short period of time, say adjusting the angle of the top to get it just right.
