[Big or small chainring (engineers?)]

More teeth on the chain shares the force better so less wear too.

[Adding 3-speed gears to a single-speed bike]

Maintaining chain tension is the biggest issue probably and, if you are changing the gears remotely, if there are enough braze-ons. One crazy sounding idea I tried was to make a 3x1 with a chain tensioner. So you add a front deranger and install a triple. that gives quite a large range of adjustment and worked well. I used an old bolt on downtube shifter.

[Parts imported via USPS from USA]

It will eventually be at the local Post Office that usually delivers your mail. They will send a slip to collect it from the Post office if you are lucky. It takes a while to get there. The post office has a tracking app for foreign parcels and it will eventually give an Xnnnn code that, if you are lucky, they can use to find the parcel. At my small dorp they just walked around and looked at every parcel. It takes more time than seems reasonable so you do need a bit of patience. 

[(why is there no) bike touring/bikepacking section here?...]

I think a bike adventure/bike packing/bike touring forum is a great idea.

[Brooks saddle rail repair]

Bike24 sell Brooks spares. A quick glance over their offerings looked promising as I did see rails etc for sale. 

[Great Divide Mtb Trail]

Are you going to the full route this time?

I hope to but have to be realistic about time constraints so I may have to settle for less. Maybe do some of the trail I could not do last time.

I did a section of it from Montana to Colorado. Fabulous experience. Plan to go again next year. Happy to help with any advice.

Sad to hear about your loss and the loss to the cycling family of such a bright star.

[Trek 810 rear disc brake bracket]

I have a 1999 Trek 810 single track. Its not a looker but its my first brand new in 1999 and its been up and down the old tokai and survived to tell the tail. (the bike below isnt mine but thats how it looks)

 

 

 

I want to fit a new crank, fork, handle bars & stem and a single speed conversion just to modernise it a bit to make it a fun runner and breathe some new life into it. Big question is...how do i get a rear disc brake onto this frame??

the non-drive side has these two rings welded to the frame (drive side as well as seen in the pic). are these potentially a brake caliper adapter mount? if not where do i get a bolt on bracket to mount the caliper onto in cape town maybe? also...if the rings aren't brake mounts...what are they

 

any thoughts, ideas and suggestions welcome

Hi,

 

Sadly those are rack mounts and not the right location or strength to accommodate a disc mount. For cost and effort of brazing a disc mount on, repainting etc, you would be better off just running a nice set of Vees or adding a front disc. I ran an On-one frame with that configuration for a couple of years and was never short of braking power or fun.

[Cape Epic on a Singlespeed?]

In 2007 myself (South African) and my my mate Chris from the USA did the race on steel rigid singlespeeds. I believe this year William from William's Bike shop and a mate are doing it on singlespeeds.
