Current Projects chat and miscellany

Pop in and take a look at our Seta Giz, I'll even get it down off the wall if you want to have a look. It's pretty light (sub 7kg)

How did you get on? 27/14 was a bit heavy in places, but I really couldn't be arsed to get involved in a sprocket swap for just one ride. If we have more fresh powder over Christmas, I'll stick a 15 or 16 on there.

Yeah was pretty good really. No massive climbs, but a few short ones and only failed on one in Burnham Beeches where the snow had be trampled into a very bumpy surface by walkers, lost traction and then was screwed. For plowing through powder it was still slightly hard work in places, but I think it always would be, was able to keep up a decent cadence so as to make it sustainable. The real killer was the trampled snow, but that was more because of how bumpy it was so tried to keep in the powder where possible.

Project for my girlfriend.

My road bike is getting a new 'cockpit' and finally completing my DA 7700 group set with my new leavers. Anyone got a 27.2 Dura Ace seatpost they want to sell me? And a black Fizik?

About to finish my everyday bike. Unknown frame (Cinelli BB, Columbus SLX tubing). 105 and Ultegra throughout. Just need 27.2 seatpost and seatpost bolt, anyone got anything?

Gizmond, Mack lightweight l/f hubs + mavic open pro's?

@snoops, is that this frame? http://www.retrobike.co.uk/forum/viewtopic.php?t=110134 if not, might give some more info.

Nice! Looks proper man-sized too!

Cut down the steerer! Nice hubs.

Maybe a 5mm or so, but no more than that.....
I like a flat bar 3 degree back sweep.....
All my bikes are the same ;-)

i love zen rings...

@Superjoe - Me too that ring is 45t, seem a bit hard to find here in that size.

People always think my bars are wide too, about 52cm

'Bout the only angle shot you can't see how wide your bars are...

52cm. That is pretty wide for a road bike.

Gizmond, Mack lightweight l/f hubs + mavic open pro's?

Do you know the weight of the Mack lightweight hubs?

Was thinking American Classic track hubs to IRD aero rims with CX Rays, which should be about 1450g the pair, but not would prefer 28 spoke rear if the Mack hubs are in the 180g ballpark.

Dolan Seta 1.1kg (with headset and seatclamp)
Carbon Fork 360g
Carbon Seatpost 200g
Omnium 800g (with 3/32nd ring)
Conti Supersonic tubes 2x50g
Veloflex corsa 22 tyres 2x 180g
chain 300g 3/32nd
cog 50g 3/32nd
DA SPD SL pedals 260g
SLR stripped saddle 120g
Carbon stem I already have 110g
EC90 TKO bars 230g

I doubt that a Seta is 1100g even without the headset.

Veloflex Corsa 22s are a bit more than 180g, mine were 398g for the pair

Avoid Supersonic tubes, they are light but shit. Latex ftw.

Omnium @ 800g? Only if you can find a chainring made from Helium. I think my sis-in-laws Omnium came to about 1kg with the stock ring. If you want light, I'll sell you my TA cranks, 728g for cranks, BB and all bolts.

Mr dolan was kind enough to weight a frame for me, 1068g including clamp for the one he had to hand. Might have under estimated the headset weight quite a bit.

I am not set on omniums just an idea, but there are plenty of other crank options below 800g. My road FSA carbon ones are way under 800g with chainrings, bolts and BB. No 1/8th stuff though, the chain is just to heavy.

Thanks for the offer of the TA's but I'll pass, I want the bike to look good too ;-)

2nd what MDCC said .. Challenge Superlite Latex Corsa Tube 65g average on the ones I've weighed if your worried on the weight of Latex tubes

my Corsa 20's were 187 and 189 btw but they where early ones with the fading labels so I'm not sure if the construction has been changed slightly since then?

great project gizmond!!!

Might have under estimated the headset weight quite a bit.

About 60-70g for an integrated headset.

KMC X9-SL chain should be about 230g for a track bike, and for track use you could get away with an alloy sprocket at 1/3 the weight of steel if you find yourself close to your target weight. Some little things that make a difference are seat clamp, basic ones are heavy and light ones need not be expensive, and headset adjuster/fork bung is a place where you can cheaply shave off 30g. For a weight weenie fixed, I'd probably go for a bolt on sprocket just because there are some light front disc hubs which can be hacked, whereas the only vaguely light track rear hub is the AC and it's a bit limiting being 24h only

MDCC, which front disc hub would you use in that scenario?

I'm just considering a wheelset myself, so I'm interested to know. I certainly don't need 32 spokes in my wheels as I am a short and skinny guy.

(I feel like I've been asking you to do my research for a bit, but I can't resist asking since you've already thought about it).

MDCC, which front disc hub would you use in that scenario?

With the proviso that I wouldn't, as I'm not in the market for a weight weenie fixed bike, but M5 and Extralite have disc fronts in the 100g area, M5 in 32h only but with conventional spokes, Extralite in a choice of drillings but with the hassle of straight pull spokes.


I haven't looked at either in detail to see how tough the hack would be to convert them to 120mm bolt on fitment. Either way, you're looking at close to £200 for a hub and probably another £100 to get the custom axle + fittings made

Cool, thanks for the info. Alloy cog and X9 SL chain. Added to the list. :-)

Just to be clear, it is not really for the track, otherwise I would just go with light carbon tubs and be laughing.
It is for 'training' and generally riding some miles on. I will probably give it a few laps, but the PX is nicely set up with the SRMs and a full compliment of nice bits to use on the track.
