Who fixes their won tubs?

Postby brit66 » Tue Sep 24, 2013 11:10 am

I used to ride tubs back in the 80s when I got my first 'good' road bike (Reynolds 531 steel frame, ah those were the days :)), but I remember buying a new tub each time I punctured... those were crazy times! :shock:

Anyway, I'd like to ride tubs again but being all grown up and money conscious now, I will only do so if I can fix them myself.

So, for those who repair their own, how easy is it? Is it a case oflooking at the odd article/YouTube video and just giving it a go?

I'm not willing to pay someone else and I'm pretty dextrous with my hands (ooh, er missus), so am thinking it can't be that difficult... or is it? :cry:

Thanks

I used to race in the 70s and 80s and always fixed tubs. You find the puncture, cut through the stitching, repair with a patch then resew with a sail hook and yarn. It is a royal PITA. You must have been rich to chuck used tubs away.

I ride road tubeless now.

It is not difficult... but it is time consuming... budget for 1 hour to fix a puncture once you know what you are doing

i save them up, then repair in batches of 3-4, over many days

exact technique is...

open them up where the repairs are needed, have a glass of wine

a few days pass

use some old carcass to patch any bad cuts, have a glass of wine

a few days pass

patch the tubes, have a glass of wine

a few days pass

sew up, have a glass of wine

a few days pass

reglue the basetapes to the tyres, have a glass of wine

a few days pass

glue basetape ready for use, have a glass of wine

i.e. just fit in the next step when there's a bit of spare time, oh, and have a glass of wine

I love tubs

They're so mysterious

All I do is when I get a puncture I put Tufo extreme sealant into the tub...pump up and go and it's good for another 5/6 months...and even stops me getting new punctures and I don't have to take the tyre off...simples.

I tried that - the sealant would blow out at anything over about 70psi...

I suppose it also depends on the size of the hole. But yes, sealanet is a temporary repair, which can outlast the life of the tyre or not, but it is still not ideal. Patching the inner tube is the long term solution

No chance I'll ever repair a tub, I couldn't even finish reading that post!

I started repairing tubs when I was 12... self taught, its a piece of cake. As long as you use the correct needle and threat, plus a sail palm or decent thimble, its easy.
Don't let anyone tell you its mysterious or difficult, its neither.

I found it really easy. I use dental floss as thread as I find it pulls through easier due to the wax on it.

I use some Kevlar thread that I got a few years ago as a free sample from Dupont.... 8)

Thanks all for the tips. I thought I'd be put off by but it doesn't look like rocket science does it.

I like the thought of tubular wheels for their strength and lightness... and changing punctured tyres easily. Apart from repairing them, the only other slight downside is carrying a spare as I know they don't exactly pack down small. I suppose a spare and some sealant is the way to go.

a light tub folds up almost as small as an inner tube (that's a conti inner tube on the right, credit card size thing in the middle for scale), i carry that plus some tufo extreme, one lezyne matrix tyre lever to help get the old one off, a valve core tool so i can squirt in the sealant

It's one you didn't pay for... they are often broken and need fixing

Ooh, I had no idea they could be that small these days. :o Mine were like tractor tyres I seem to remember, although they were cheap and it was 25 years ago. :cry:

bear in mind this is just a get-me-home tub, not one i'd want to ride on a lot, 'proper' ones like a lovely veloflex carbon don't fold up that small
