Looking for a light and fast tire/tube combo for hill climbs. Did a search but everything I found was quite old.

Veloflex record clincher (22mm width 145g weight) + Vredestein latex tube (47g claimed, mine were 49g/50g on the kitchen scale) = under 200g combination, super low CRR.

I wonder how long before a puncture though.

Doesn't matter, it's only for hillclimbs.

I used to use vittoria track stuff bitd.

Thanks for that. Yup just for hill climbs. What about Conti Supersonic?

I've heard the Ultremo ZLX tyres feel really really fast, but are way over the claimed weight of 150-160g. Also, all the marketing material around them always emphasizes that they aren't very puncture resistant.

Missed that bit. Veloflex sounds perfect. There are some very light continental tyres and they end up being the same weight.

Surely tubular will be lighter still due to the rims.

Personally, bad experience with lightweight tubes as not being as durable.
Get Kenda standard tubes and enjoy fewer punctures.

Races are typically 3-10 minutes long. It's hardly a high risk.

Unless you are already tied into clinchers, i'd be looking at tubs, nice light, low profile rim (carbon if budget allows) then some track tubs.
If you are clinchered up already, some sort of lightweight open tubular. Challenge, Vittoria or Veloflex and a latex or supersonic type tube. Maybe go a bit larger and softer (25/90PSI) to give yourself a bit more traction when it rains!!

Conti Force/Attack or even Attack/Attack could be a good "heavy" alternative, they are about 185g but have the same puncture resistance as a GP4000s and basically the lowest rolling resistance in the business, which might trump the extra 40g.

I've been running these with Latex tubes on the normal road bike without problems this season.

conti GP supersonic 20mm are 140g.
Veloflex open record 20mm are 130g.

However veloflex sprinter tubs are 210g and with the weight saving of a carbon tubular rims (can be as low as 250g) then tubs would be lighter.

Also a fixed gear hubs are all more weighty than a geared hub. Although a fixed gear hill climb bike is quite appealing. ridea do the lightest fixed gear hubs that I know off and then there is Mach.

Another vote for Conti Attack/Force and latex. Roll great, mid weight and extremely durable. Having said that I have a pair of 23 Supersonics with latex on a 23mm wide carbon 38 China rim and I love that combination.
