Bob Jackson Audax/Commuter build

So the mercian is too fancy for commuting duties, so I bought this Bob Jackson Audax from Ebay.

So far purchased, NOS 105 threaded headset from Paul Hewitt and I have a 9 speed 105 triple groupset.

Debating flat bars or drops, Wheelset and dynamo for lights to be ordered.

Looking an SR Laprade seatpost as well.

I'd go for a flat bar with a 1x9 set-up.

its gonna be a triple, with 12-30 on the back and a rack.

Theres the 9 speed tiagra flat bar shifters, I already have the sti's for drops though.

Shimano Dynohubs are a lot, lot cheaper than SON. SON have slightly more gain with less resistance but, they cost. (lovely but perhaps not commuter material...)

Le Manfriend swears by Mavic touring rims, Mavic in general do good rims for a good price in my experience.

I like my drops for windy Belfast, that's perhaps just me ;)

I gave a Shimano dynamo hubbed wheel to mavic a319 rim for sale #spamming

Is the seat post the one with the sort if slots reamed out?

yep! [](http://velobase.com/CompImages/SeatPosts/8F51324A-E883-49F4-82EA-27D4D96B4621.jpeg)

The wheelset is shimano nexus, laced to rigida snyper. 17 across so will take 28's no problem.

I know this is at the cheap end of market dynamo wise but this is mean to be more a commuter build on a budget rather than something for full tilt audax etc.

Well there's that many traffic lights in town and dopey peds on the greenways full out speed is nearly impossible anyway ;)

So my 105 headset arrived from Paul Hewitt, just dry fitted the cups, the top bolt isnt screwed right down but holy fucking spacers batman. This bike has been built up too before! Debating how much to cut though. p.s Ignore my filthy spare room lol

i've bought a couple of the fluted SR laprades before, they weigh a f*cking ton! there about 4 mm thick.

get something modern, will save more than a couple grams

I do have one of those posts though doing nothing in my shed. Happy to send it for postage plus a pint.
