Here's a look at a new Moulton SST build that I just finished up from a frameset . This is a 20 speed with 56/39 11/28 gearing set up up as a quick flatbar bike with SRAM trigger shifters and SRAM Force derailleurs.. the front derailleur employs YAW technology which angles the cage on shifts allowing for more chain room when at extreme angles.. basically quiet when severe crosschaining takes place..

The SST frame differs a little from the TSR series in that it has stainless steel dropouts front and rear instead of painted chromoly.. also uses true 130mm road spacing with typical road dropouts as opposed to 132mm TSR spacing (a compromise spacing which can accommodate road or mountain hubs and has angled dropouts which can allow the rear wheel to be moved fore and aft a few millimeters so that hub gears can be used more easily). The SST has a progressive front suspension spring standard as well as a true 31.6 mm seatpost as opposed to the 31.8 of the TSR.. the front derailleur mount is also adjustable so that the angle can be fine tuned for the application .. the frame is also a bit lighter.. this fully built up SST is roughly 10.3kg .. a similarly built TSR would be closer to 11.5kg .. went for a 20 mile shake down ride yesterday and am very pleased with it..

These are like 4500.00, no?

Wow,...just,...wow,...

They can run $4500, depending on the components selected.. the SST pictured above could be had for a little more than a stock TSR-30 ..

I would guess that all the components are sourced and installed by none other than yourself, thereby cutting costs, & creating the excellence we see in this thread? It's a dang fine bike, sir. Gorgeous!

Did you build up from a frameset alone? If so, what do they ask for a frame only?

BruceMetras

Thanks, I enjoy building almost as much as riding..

Right now in the USA, they can only be sold as complete bikes with warranty etc. I don't know about Moulton distributors in other overseas markets ... might be different in Australia.

Sweet bike Bruce.

Very interesting Bruce and especially the the features of the Front Der. The ability to adjust the mounting is overdue and I know someone who constructed his own in order to give him the ability to do this.

Is it me or is the Rear Der a medium cage? It does seem very close to the ground as I found when trying a similar one albeit with 17" wheels. As has been suggested in another thread, would a Shimano Zee not do the job whilst giving greater clearance?

How would someone in the US buy a Moulton, other than Portapedal in Phoenix? Are there equivalents to a TSR 2 or a TSR 9?

Here's the current USA Moulton Dealer List

The SST could be built up as a 1x(2 through 11 speeds) if specified .. I chose a double up front as I was familiar with how well the adjustable front derailleur mount worked from having built up a few SST's, and that a double gives most people enough range for a sporting bike..

The picture is a little deceiving as it's shot looking down at the rear derailleur, so looks like it's practically on the ground .. in actual fact, the bottom of the pulley cage is above the brake surface of the rim when vertical.. if I were to remove a link or two, it would have a more horizontal plane.. I've never through the years had a ground strike on a rear derailleur, but I'm exclusively riding my little wheel bikes on pavement.. I also like the SRAM 1:1 actuation ratio components ..

The Shimano Zee specs list a 25t max capacity .. I'm running 34t on the above bike..

There is a option but it would not give you the aesthetics.

As mentioned in the Capreo thread the 3 pulley Suntour derailleur looks pretty good and would do the job but are apparently very difficult to find.

Apparently this comes with two specs....something I've never heard of.

"With two spec options that enable a typical MTB cassette (11-32,11-34,11-36) or a close ratio road cassette (11-23,11-25,11-28), Zee is ready to handle the needs of enduro and DH racers."

I'm wondering if it will solve my particular problem.....it's either the above...or a leg transplant from a younger person.

BruceMetras

The Zee is primarily for 1x systems .. hence the 25t wrap capacity 11/36= 25t

Which problem are you trying to solve with 369mm wheels?

onbike 1939

I need really low gears and am running a 53/39 chain-set with a 9-28t cassette at the moment. I'd like a yet lower geaar but having tried a 32t sprocket I run into difficulty as this would seem to require at least a medium rear der. which comes down below the braking surface of the wheel.

BruceMetras

You could compromise your almost 98g/i to something more in keeping with older legs .. if you could get by with high 75 to 80g/i you could run a modified Capreo (9/32 or 9/34), short cage derailleur and a single 40 or 42t up front .. nice and slick ..

Other obvious option is a Schlumpf Speed Drive (1.65 overdrive) or even the less expensive Patterson 2 speed crank (1.6 overdrive) .. then you could run your stock Capreo, short cage derailleur and still have sub 20g/i to mid 80's ..

Thanks for the Moulton dealer list. I do get to Denver once in a while and would love to actually ride one before spending lots of money and not being happy with it.

Hardly a week goes by where someone with a spare $20k doesn't come by the shop and order up a New Series Moulton.. I'm probably the major reason why Moultons are in such short supply worldwide .. a never ending flow of cash to Marin County... life is good... I enjoy living on my boat also..

Didn't they tighten up on the live aboard sewage dumping practices of Anchor Out Sausalito Richardson's Bay crowd?

Thanks. I'm going to have a hard think about this.
