new bike day - I hate inner tubes

Wow is this what roadies do on new bike day? Sounds like a chore.

Looks nice

i can do shits that weigh 1lb and you are worried about 150 grams

get a life man.............. ;o)

nice bike

No problem with inner tubes here! Were you using levers to refit? If so practice your technique, no levers..
Nice bike though!

no I bought an alu bike over a carbon one. The weight of the bike isn't an issue, the inaccuracy is.

Put another tube in and it was fine. Not had to put a tube in a tyre for god knows how many years and certainly not one as small as the road tyre.

The weight of the bike isn’t an issue, the inaccuracy is.

Every single component of that bike will have upper and lower weight tolerances given to them by the manufacturer. For some of them, it might only be 2-3%, for many, it's more like 8-10%.

The fact your bike is only 150g (well, let's call it 200g as the small size frame and slightly smaller components would add up to about a 50g weight saving from experience) over the (always very optimistic) quoted weight is actually pretty impressive I'd say! It's within 1.5% tolerance anyway, which is far closer than any of the individual components will be measured to...

This is the feeblest "my bike is heavier than it should be" thread I think I've seen in a very long time on STW!

Lighter wheels coming tomorrow.

And as of tomorrow, your disappointment will no longer even be relevant anyway!

New wheels are quite nice looking. 1595g Vel RL28 from sigmasports. £171 black Friday with an extra 10% off. Stock wheels level 1 are 2005g.

Got TAXC rollers coming tomorrow. operation get fit will be in full effect.

So you decided against the light wheels then? 🤪

@tthew Couldn't find any lighter for the price I paid. I did look.

There's got to be 150g of spacers under that stem.

Is a lighter bike better for rollers then? Like the thing with the aeroplane on a treadmill?

Sweet bike too.

I don't know which is more worrying... OP weighing the parts of his bike, or Ton weighing his shits:-0

Wait until you weigh the wheels and find out the measured weight is without valves and rim tape. I think you're looking to be disappointed again.

@thebunk

less effort to lift the bike onto the rollers

That is very heavy for an a road bike though isn't it. I recently bought a steel frame and fork Cinelli Tutto plus and admittedly it doesn't have gears but everything on it is cheap and heavy (only really wanted the frame and it was an insurance replacement bike).
After building up some new wheels (which still are not light at 1860g) and swapping a few parts with stuff I already had it weighs about the same as your bike. And it feels like a tank compared to the 6.4kg bike it has replaced.

As for inner tubes, the original tyres/wheels couldn't be tubeless so I tried some X Tubo tour tubes which apparently are pretty much puncture proof (only for 30-50c tyres though). 2 months later and so far so good and even though I now have tubeless rims and tyres I am still using the X Tubo tubes.

That’s not a horrendous weight for a stock bike. Looks nice.
My winter bike, carbon Trek Domane with 105, that was over 9kgs stock. About 8.5kgs now.
My Planet X Tempest is supposedly 9.3kgs…. Will weigh it later with bottle cage and pedals. My money is on it being closer to 11kgs…I’m in the process of replacing the stock parts on the Tempest. Reckon I can get it down to just about the advertised weight and that’s with very light wheels, Zipp carbon bars, stem and seatpost.
I do really enjoy the tempest, but riding it after my 7kg summer bike is a bit tough.

That is a little heavy but it sounds like a lot of the weight is in the wheels and tyres.

I think my caad12 disc is about 8.4kgs with di2 Ultegra and Hunt 4seasons road wheels / GP4000s in 25c.

With the standard wheels it was probably a lot closer to 9kgs and the frame is only meant to weigh about 1150g (mine’s a medium).

What rollers have you ordered?

You might want to keep the stock wheels/tyres/tubes on for roller duties as you'll be looking for ways to increase resistance! Heavier wheels/slower tyres/lower pressures can be a useful way to eke out some more resistance from a set of basic rollers.

For all the fuss about the weight and expense of new wheels, you could go much faster on the road if you hadn't set the bar and stem up in the least aerodynamic position possible.

That is very heavy for an a road bike though isn’t it.

I dunno.

I have a hi-mod carbon Boardman with tubeless carbon wheels & seatpost which weighs in at 8.2kg, with a comparable disc groupset.

The extra kilo-and-a-bit for stock wheels and alu frame seems reasonable.

I think disc brakes have just added a bit of weight to all road bikes.

Aye, but you can't buy a different shaped body. Speaking as a man who is apparently (according to his physio) quite flexible for a 39 year old male cyclist, I still have my bars reasonably high on my road bike, because that's what shape I am, longer legs, shorter upper body.

So assuming the position of the bars is 'fixed' then you might as well focus on gains elsewhere, aero wheels, whatever.

edit:

I think disc brakes have just added a bit of weight to all road bikes.

Yep, 9-10kg seems par for the course now for bikes up to and including £2.5k it seems. I think Trek were pushing one of their Emondas (the endurance one) at over 10kg for £2200 (this was a year or two ago right enough, I just randomly remember that example).

weighing his shits

doesn’t everyone go on the scales before and after a big job?

With the length of those shifters you must be able to save 50g on a shorter stem? Stick wheels are an easy 300g saving. Mine will be sub 8kg with a lighter fork and no mudguards. Some of those alloy steerer forks come out at 600g and another 300g can be lost with a full carbon upgrade.

Difference in frame size is seldom a big weight difference.

Shifters … ok. I read shitters at first

With the length of those shifters...

It has to be said, Shimano Hydraulic brifters really are the most fugly component on any road bike.

I have one of those, it's a white/red colourway from 2019. Nice bike, fairly comfortable. The 105 groupset is still going strong after 3200 miles. Currently sporting some mudguards and Conti GT's for a bit more protection in the winter.

@stcolin Its the same frame and forks as far as I can tell. What mudguards you using? Doesn't look like you get much clearance for tyres with MG on.

@TiRed Forks are full carbon.

@munrobiker Set up for comfort

@13thfloormonk Tacx Galaxia Advanced Roller Trainer from startfitness

Got some new tyres. Goodyear F1 tubeless from probikekit. £67 for the pair. New saddle coming too as the one on the bike is painful. Really happy with the bike although my fitness is shocking.
