My primary goal was to build a fast version of the Moulton TSR and to keep it as light as possible while using components that still harmonized with the frame:

I used the following components:

Alex moulton TSR frameset
Tune MAG 170 and 70 hubs
Schwalbe Durano tires
Tune Big Foot crank
TA Axix Bottom Bracket
MKS - Royal Nuevo Pedals
Highpath EGGring custom oval chainring (54 teeth)
Sram XO cassette 10x 11-36
Sram XO 10x Rear Derailleur
Sram 500 TT Shifter
Paul Thumbies for Sram
KMC X10 SL chain
Brooks B15 Swallow Titanium saddle
Tune Starkes Stück seatpost
Nitto - Bullhorn Bar RB-018
Dia-Compe 287 V-Brake Levers
Moulton Rear Day Bag Carrier
Moulton Rear Day Bag

Total weight without Bag Carrier and Bag and Pedals is around 10kg.

Very nice actually. It just feels great to have fast race tires with 110 psi but anyway being able to ride on uneven surfaces comfortably thanks to the suspension. Also does the frame feel very warp resistant thanks the the space frame construction.

The geometry feels very comfortable to me but still has a sports-feeling to it. The only disadvantage I see compared to a normal race bike is the extra load for the suspension and the movement of the front suspension when out of the saddle.

I also like the gear ratio with the 11-36 cassette. Of course I don't have as many gears inbetween like with a standard 2x10 race set but the band width is the same and I don't have any overlappings.

It's nice to see something different! Very interesting.
How does the suspension behave on normal, fairly smooth roads? especially the front. Any up/down oscillation?
Were you able to buy just the frame?
It seems to me that the Moulton frame comes in only one size; could you measure the effective TT (and if you know them, head/seat angles...)?
many questions, sorry...

I don't feel the suspension on smooth roads as far as I can tell, but I don't have that much experience yet for the simple fact that I completed it a few days ago.

I got the bike in November when I was in London over the weekend. There is a frameset for £ 900.- and the TSR9 bike with all parts for £ 1200.-. The frameset is for caliper brakes and the complete bikes is equipped with V-Brakes. I took the complete bike for the simple fact that the frameset was not in stock and I wanted to ride it during the weekend. Now 4 months later the only part that is still from the original bike is the headset and the bike is worth aprox. 4 x more then the original sales price :-)

Can you hint me to a site that explains me how to measure the TT?

Thanks!
effective TT is the horizontal distance between the axis of head tube and axis of seat tube, measured high on the head tube (but that doesn't matter if the HT and ST are parallel).

The top tube measures 56cm.

Thank you. Please report back about the ride once you have ridden it more.
