Re: What chainring and rear cog for Rohloff?

These X1 chains I notice are no longer available, I have one spare which is about to get put on the bike, so will be looking at what is the nearest equivalent new chain. Also my chain of choice. They've still available and have been renamed E1. I stocked up while Planet X had stock for £18, they mi...

Re: What chainring and rear cog for Rohloff?

I have had good (low) wear rates with a KMC X1 3/32nd chain, a Rohloff 17T sprocket and a Surly 42T stainless steel chainring. Used to use chainrings of 48 to 46T, but nowadays quite happy on a 42T, especially when heavily loaded. On a 26" wheeled bike. Good for 25mph on the 42x17, happy to fre...

Re: Extra bit of front mudguard?

Spray from the top of the front guard is an issue I have suffered with at times, going downhill, into a strong wind or anytime when over about 15mph. The tyre makes a huge difference, I used to run 26 x 1.75" Travel Contacts, but since changing to 2" Marathon Supremes the amount of water r...

Re: Converting a deraileur bike to use a Rohloff hub

As mentioned a week ago, here are a couple of pics of my set-up. All straightforward, just had to bend the tip of the torque arm inwards so it aligned with the clamp on the LH chainstay. A bit of a juggle to find the best gear box/cable routing, otherwise the gear change can get stiff. Have always h...

Re: Rohloff questions

No secret that this is my first encounter with Rohloff; so what do experienced users think of this thing? https://live.staticflickr.com/65535/50750934162_bc8db33287.jpg IMG_5323 by 531colin , on Flickr The cable drum is a bit of a faff, due to not doing it frequently I find myself reaching for Rohl...

Re: Converting a deraileur bike to use a Rohloff hub

What the OP is trying to do makes complete sense to me and really should be straightforward. My Rohloff was bought secondhand some time ago, probably well over 20 yrs ago, it is a 4 digit serial no., disc version with the external box. It just fitted straight onto my old 26" MTB, there were no ...

Re: Suggest a dynamo front light please

What a lovely commuting route you have! Nice distance too. Sounds very similar to the route a relative has in Germany, he had a bad hit with a deer a couple of years ago, but that seemed unavoidable, not due to poor lighting, the deer just leapt out in front of him. Luckily he escaped with bruising ...

Re: Power meters

Thanks Des49 and Elcani. The assioma pedals are the ones I’m considering, have heard good things about them elsewhere. Not that keen on having to take them off to charge, but if that means a more reliable power meter then so be it. May also mean some new bike shoes as I currently wear MTB ones, but...

Re: Power meters

Most power meters will be able to talk to a bike computer like a Garmin, Wahoo etc., or to a phone app. Which power meter is a bit of a minefield. These gadgets are not cheap and reliability is an issue with many, especially with long term usage. Most affordable are single sided left cranks from Sta...

Re: Internal cabling grommet lost inside bike

Another possible way to retrieve such items can be to use a vacuum with a stocking fitted over the end of the hose.

Generally you just need a lot of patience and preserverence, I recently had such an experience getting a spoke nipple out from inside a rim.

MTB White Spider frame for racing, rigid forks. did you get what you wanted ? Yes, only thing was the SLX frame did not come (as r...

Re: Is this crankset free enough?

Looks fine to me and in line with what I have experienced. I fitted a couple of bikes with more expensive Hope stainless steel bearing bottom brackets and these were the same as the Shimano versions. Fit the pedals and the cranks will spin a bit longer. It is really difficult to tell if a BB is stif...

Re: ...about lead times for custom builds?

Blimey, how things have changed! When I bought my Roberts in October 2006 it was 4 weeks from ordering to riding away on it! Wow! How did that happen? My experience over 5 Roberts frames between myself and my wife have been many, many months wait, like plan for next season. These are from 1986 to s...

Re: Advice on triple chain set

In my experience a 10" spanner is rarely long enough for the task. As Brucey points out clamping the tool to the cup is very important, otherwise something will slip under force and frame damage could occur. Below are my BB removal tools, note the bolt to secure the removal tool to the cup and ...
