doing what i hope to be a lightweight hardtail build, wheels tyres frame and fork, brakes, saddle are all as light as i can get them.
without going silly what £s and weight can i expect from an 80mm stem, lowrisers seatpost and cranks + pedals?
any suggestions?
looking at used kit, so budget is roughly £50 each for stem bars and seatpost, £100+ for some cranks, £50 for some shimano compatible pedals
to aid my ahem spreadsheet, anyone know what i can expect these things to weight in gs?
