That time for new rubber and interested to know what people ride on.

Since starting road cycling over last 5 years ive always used 25mm tyres, my last bike came with 26mm S-works turbo tyres, but thinking of going back to conti gp5000’s.

Ive read a lot about 28mm maybe being more comfortable and a wiser choice these days, especially on british roads, but then generally was happy with 25mm when i used them.

In terms of my riding style I dont really race but do the odd sportive, and do like to push myself and break strava segment times etc., so looking for good performance as well. does 28mm suffer performance wise at all?

Also not going to fit until through worst of winter – but looking to buy soon if i can.

Interested to hear opinions! Thanks.

Is that because of the lockdown ban on group rides?

Ride 25’s most of the year

Ride 25’s most of the year and find they are nice and fast for me giving me thr grib I need. I do ride 28’s on my wet weather/winter bike because I just want some more rubber on the ground to help with greasy roads and also have slightly better protection against potential punctures.

Hard to comment if my 28’s are slower or not because the bike I ride them on is Al frame instead of Carbon, so naturally it’s a slower bike.

You can’t make a simple comment about tyres without airing your obsessive and often offensive views on heavier people (views which in this instance are totally wrong, if 28mm tyres are only for fatter people why are so many pros riding and winning on them?). Keep on doing it and I’ll keep calling you on it until you follow your own advice by growing up and stopping calling people with weight problems “fatty”.

I use 32mm GP5000s and think they are fantastic. If your frame can take them, I don’t see any downside. 

On a downhill segment that I must have ridden 0+ times, I set a segment PB on my first time with the GP5000s. It’s one of those where you pretty much roll down and let gravity take you so I’m convinced it was all the tyres. 

I’ve had one puncture in about 4000km, however, I can caveat that with the fact I’ve been using the bike less for communing over the last couple of years and may be more selective of when I ride.

Conti GP5000’s all year round

Conti GP5000’s all year round for me, 25’s but if there was room in the frame I would use 28’s

I’ve raced on GP5000 in 28mm
I’ve raced on GP5000 in 28mm width (I’m 70kg before we get on to any kind of rider weight debate 😉 )and it wasn’t the tyres holding me back! I’d probably buy either 25 or 28 depending on which were cheapest or available at the time. Or as others have suggested the ones which fit your frame clearances and wheel width. GP5000 are a fantastic tyre, I think they felt noticeably better (faster/easier rolling) than the Hutchinson Fusion and Vittoria Corsa’s I had on othe bikes.

I wouldn’t go as far as 30mm GP5000 as I know it’s a different sort of tyre but the Spec Roubaix tubeless I have in 30/32 is somewhat sluggish and seems to lose the zip of a narrower road tyre.

I mostly ride on rough roads, so I’m on 28s. I’d probably fit 32s if my bike would take them.

The performance difference between 28s and 25s is going to be tiny, so if you’re not racing I wouldn’t worry about it. Max pressure for my tyres is 115 PSI, so it’s not like I can’t pump them up as hard as I want to on the rare occasions when I ride on smoother roads.

I have 32s – they are great
I have 32s – they are great for the potholes and general uneven roads here.

The roads I ride are so
The roads I ride are so broken and potholed that I am thankful to be on 45mm tyres at about 2.5 – 3 bar. When, occasionally, I am visiting other regions where the roads are better, I just pump the tyres up a bit more. I’m not sure whether there is any penalty for having fatter tyres, but I am sure that I would break something, either the rims or myself, if I was riding on skinny tyres.

Lots of tyre comparisons for rolling resistance and also durability.

I ride 25s at 115psi. Not too worried about comfort.

So 32mm and 37mm are for real PORKERS, are they? FFS.

Just because you use 25mm does not mean wider tyres are only for overweight people. My teenager daughter rides daily on 37mm tyres but weighs about 35kg.

I think it depends on quite a

I think it depends on quite a few factors: 
-Current rim widths, external and internal.
-Do you have the clearance to fit a bigger tyre? Remember it’s not just about width but height too so check clearances at the seat tube (I fell foul of this when I tried fitting 30mm). 
-Also, what weight are you? If you’re on the lighter end then I’d stick with 25mm as the lighter weight of the tyres would be more beneficial.

Like that “fatty” (your word) Colbrelli taking Paris-Roubaix on 30mms, or the 15/25 teams in this year’s Tour de Flandres who used a minimum 28mm tyre? Your sad obsession with banging on about other people’s weight is extremely disturbing and would appear to indicate underlying psychological problems – or maybe you’re just plain spiteful and judgmental.

I stick with 25mm tyres, don’t see any upside to 28s, think 28mm tyres are designed with the more “rotund” in mind. I also have a bike with 23mm tyres on and to be honest even that isn’t too bad.

Often find gp5000s are on offer at probikekit by the way, they do flash sales fairly often and their normal gp5000 prices are competitive in any case. Last time I bought gp5000s I think a pair were about 65 quid on a flash offer.
