Re: Flat bar conversion

I don't know about Sora front shifters but previous threads about converting flat bars to drops highlighted an issue with flat bar shifters for the front mech as they all had MTB cable pull ratios making them not directly compatible with road mechs. This was not helped by Shimano referring to the fl...

Re: What 18650 batteries for your battery pack?

Couple of guys I met locally are converting bromptons but they use off the shelf power tool batteries. https://www.nanoelectricbikes.co.uk/
It's the way I would go if fitting a conversion. :wink:

Re: PD-M324 Pedals - Are they shot?

Bin, but before you do chuck them up in an electric drill and using Emery paper grind out the worst of the pits. Rebuild and they will still be rough but you may get some more milage before you bin em and it doesn't cost you. :wink:

Re: converting tiagra rear road hub to 135mm oln

if you are familiar with the workings/parts of one of those hubs (or similar) here goes..... just use a suitable cone spanner and open-ended spanner to loosen the locknut on both sides and insert a 2.5mm washer or spacer between the cones and the locknuts to make the OLN (over locknut) dimension 13...

Re: Primus Pump Lucky I Did Not Need It

Checked my box of spare pumps but I couldn't find any with those screw on caps. Plastic pumps were pretty common and supplied with bikes maybe 20 years ago. Most had those screw on plastic caps. I suspect they had failed in the manner yours had so have been binned. :(

Re: Epoxy

Just a little warning if you are using anything with acetone. It can melt your plastic lenses. So be careful if you have plastic lenses in your specs. I had plastic lenses in my specs as my optician recommended these for cycling as less prone to shattering in the event of an accident. They got splas...

Re: Primus Pump Lucky I Did Not Need It

Those screw on caps may be a standard item across a range of cheap plastic pumps. I had a similar failure on a pump which came with a new bike. Fortunately it was a MTB wheel which needed pumping on the road following a visitation :( The pump held together with hand pressure to get enough air in to ...

I rotate the chain on the tandem every month now. The old chain gets cleaned and hang on a nail with a new one for comparison behind. I don't get too hung up about chain wear :lol: Bruce's post from 3 years may provide some help. You've got plenty of time to take it in whilst it's still raining. htt...

Re: Nutrak Slick eBay

My experience of Nutrack Marathons from twenty years ago was that they were very hard wearing. I would get 12k miles out of a rear 700c tyre. Downsides were they were slippery from new and you had to be careful for the first couple of hundred miles. Not the tyre to fit in the winter when they were s...
