Re: Moulton tsr2 bottom bracket spec

My TSR2 originally came with a Sturmey chainset like this, which suggests a 119mm bottom bracket.

Re: Dura Ace downtube shifters - don't believe everything retailers tell you...

Hmmm, the 10s d/t Shimano shifters have the d ring, friction option. The 10s Shimano bar-cons do not have a friction option. That could be the source of the retailers confusion. 9s Shimano bar-cons do have the friction d-ring. Just checked actual bikes, reality is not as reliable as the internet in...

Re: 2020 Audax LeJog

My advice if he tries to put this on is to stay away, that way you will not have given him money and then been disappointed - and be out of pocket. Based on the feedback on another forum from entrants trying to get a response/refund from the event organiser following its Covid enforced cancellation...

Re: Is a Moulton a fair weather Bike.

Only you can answer that question! If you like your bikes to be fastidiously clean but don’t enjoy cleaning them, then a spaceframe Moulton probably is a fair weather bike. For myself, my bikes are tools not jewels, so I give my Moulton’s a wipe or hose down when they get too mucky, but otherwise ju...

Re: Tyre Pressures for Comfort

This is the best tyre pressure chart I've found anywhere :- https://www.renehersecycles.com/tire-pressure-take-home/ Pressures in the chart are per wheel load,most bikes(other than tandems)tend to be 40 to 45% front and 55 to 60% rear depending on riding position Me too. And the middle table of thi...

Re: I need an obsolete 52t chainring ( 122mm BCD )

I’ve had no problem sourcing 122bcd chainrings from eBay - there are two 52t rings for sale on there at the moment.

Getting a response from Hilary Stone - now that’s another matter altogether...

Re: Has anyone changed Moulton AM to 16 inch wheels?

Not my bike, but here is someone’s 16 inch AM conversion. There’s a folder of pictures on Flickr showing the conversion process. BizarreLy, they’ve used Kojak tyres on the conversion when they’re the only ones easily available in 17” :D

Re: What do you get if a Raleigh twenty collides with a Moulton Mk3 ?

My guess would be that the bike in Brucey's first post is just a mk3 Moulton that's been retrofitted with 20" wheels. There were known prototypes but they all featured front suspension. I think this is a garden shed hack. Interesting though nonetheless No, the prototype I mentioned didn’t have...

Re: What do you get if a Raleigh twenty collides with a Moulton Mk3 ?

There was genuine Moulton 20 prototype that was a cross between a Mk 3 and an R20 - I don’t know if the bike in the picture is it but it looks awfully similar. It was one of several prototypes designed by Dr Moulton at Raleigh’s request after their takeover of Moulton in the late 60s.

Re: Moulton - rim size

The whole buying bike then slowly swapping every component is something that a lot of cycling enthusiasts, especially if we do a fair few miles. Indeed. I’ve noticed that a lot of Moulton bashing that happens on this forum quote the modifications that Mick has made to his TSR as a reason the bikes ...

Re: Tyre pressure, are we living in the past?

Just to mention, I have 27" hookless clinchers (Weinmann) and inflate the 1& 1/8 Michelin Select tyres to 85psi without any problems whatsoever, had no issues cornering at speed even with my near 100kg on board, never felt they were going to blow off the rims even though the tyres are quit...

Re: Moulton - rim size

I may have opined before on this forum that I worry that the revolutionary days of Moultons are all in the past, and all we will get now is refinements and rehashes of existing ideas. I hope I'm wrong. I fear you are right. There hasn’t really been anything new or revolutionary from Moulton in the ...

Re: My Moulton TSR - a love story?

+1 But whatabout chain tension? And how does the sprocket wear? The TSR has a unified rear triangle so chain tension isn’t an issue, but all of my roadworthy Moulton’s (a TSR, an AM, an APB and a Mk3) are all being run fixed and I’ve not any chain tension dramas. I’ve also not noticed any out of th...
