Interesting short article on comparative tyre rolling resistance. I’m probably going to try Tubeless again via the new Schwalbe One Tubeless with Finish Line Sealant (that is guaranteed to not go off). Mainly as I’m planning an even next year in Nice where it is likely to be a) hot and b) have 3 v long downhills and I’m a bit concerned about heat buildup on the downhill braking and supposedly Tubeless is less prone to overheating blowing the tyre off the rim. Well, according to the Schwalbe blurb anyway.
Both wheel sets on my bikes are tubeless ready. And the Pirelli Cinturatos https://www.bicyclerollingresistance.com/road-bike-reviews/pirelli-cinturato-velo-2018 I’m currently riding can be ridden either tubeless or with tubes. Part of me wants to go tubeless simply out of curiosity. But the other part of me doesn’t want to deal with the hassle of sealant.
Yup – I gave up 3 or 4 years back as I was picking up punctures that would not seal and was noticing that the sealant was forming Coral clusters (clumps) fairly quickly. So I’m hoping that the sealants have moved on since then. Also hoping that the lates Tubeless Tyres may be a little more puncture resistant. I felt that part of the problem I had back then was that the Schwalbe One of that year were pretty sticky rubber. The ride running Tubeless was fantastic but round here we get a lot of little stone flakes in the… Read more »
If puncture resistance rather than rolling resistance is your priority, you should take a look at the Pirelli Cinturato. I’m riding them with tubes and have been very happy with how they’ve held up, i.e., no flats. Per the link in my previous post: As promised by Pirelli, our tests confirm that the Cinturato TLR sets a new level of puncture resistance. On top of that, the Cinturato also offers a very high tread thickness of 3.7 mm where competing tires generally come in at less than 3 mm. All this comes at a cost of a 40% higher rolling… Read more »
I’m after best balance between Rolling and Puncture with min Rolling being the bigger benefit.
But if you roll faster but still puncture/flat, then what price speed?
Ha Ha! True – that’s where risk and probability somehow factor in!
My latest acquisition … Kuat Transfer 2 rack for my wife’s car.
My current car is based on getting my bike(s) in upright with only the front wheel off – more secure when travelling with a bike. I didn’t want and SUV or MPV and discovered that I could manage to get 2 bikes upright in the back of a VW Golf estate. I had to take the seat post out in my previous Saab but found the Golf just works if I take the rear floor/shelf out. The benefits of being a short-arse!
I’ll take some photos in the next few days.
I need this for when we take family trips and I want to take bikes. I can get two bikes inside my wife’s car (on their sides with the front wheels off), but that won’t do if there are three of us with luggage (and my daughter’s and my golf clubs!) My car is a Saab 9-2X (small sport wagon) and I have Thule roof rack on it for carrying bikes.
My previous car was a Saab 9-3 Sportwagen too. Great car but decided it was time for a change after 120,000 miles. It was starting to get a bit pricey to run but was still a great engine (twin turbo diesel).
My 9-2X is affectionally called a Saabaru because it’s actually a Subaru WRX platform that was Saab-ified. Made only in 2005 and 2006. Considered by many a “unicorn” car with something like only 5,000 or so of them made. Mine has low miles (less than 125,000 and 14 years old!) and is great running condition. Body (mostly paint which is crap) is a little rough around the edges. And I had something hit my front bumper and cracked it. Unfortunately, no more replacement OEM front bumpers in the supply chain. So mine is “race taped” repaired (with red duct tape… Read more »
I don’t think those were ever sold over here. I did see one in a concept car Ad some years back and thought it looked really interesting.
Here’s a pic of my little red wagon. To ensure that this post is within the rules, with bikes on the roof rack.
My latest for PEZ … review of the Wahoo ELEMNT Roam. https://www.pezcyclingnews.com/technspec/wahoo-elemnt-roam-review/
I recently changed from a Garmin 800 to the ELEMNT. I would probably have gone with a ROAM but it was just in the gap when they were in short supply. I too really like the ELEMNT but the comments I have is that it does seem to loose GPS signal quite easily in trees. Maybe this is common to other units but the ELEMNT maybe just announces it a bit too quickly. On a long ride last weekend I was losing signal when my mate on a new ROAM was not. I have also noticed it going of route… Read more »
Oooooo – is it nearly Christmas………..Stelbel Part 7
That’s some nice kit! The bibs looks great. Not sure about the jersey with clouds or the arm warmers, but I’d wear the rest – and I tend to go old school – blocks of color, rather than patterns.
These are probably more to your liking: https://reggie.bike/collections/the-de-boss-series
I don’t know if kit counts as tech, but my latest review for PEZ. https://www.pezcyclingnews.com/technspec/reggie-kit-a-ride-on-the-wild-side-clothing-review/
Looks good, only part I don’t like is the Camo mix on the arms warmers. As I’ve said before, I hate Camo gear with a vengeance!
I guess sunglasses count as tech. My latest for PEZ. https://www.pezcyclingnews.com/technspec/scicon-aerotech-sunglasses-review/
They look pretty good. Not too big. Some of the ski goggles style that are being worn these days just don’t rock my boat at all.
Like this?
Yeah I was thinking of the Yates’
I like a bigger frame on my sunglasses so some Oakleys (Sutros) and 100% glasses work great. But those Scott ones are a tad too much IMHO.
I am 5′ 9″ and ride a size 54 Pinarello Marvel frame. The 120 mm stem that came with the bike is too long for me and I experience lower back pain when I am in the saddle for more than an hour. I am thinking that a 100 mm stem is the correct size for me. Short of a bike fit, is there any good way to tell what the correct size would be? I have to order on line as the stem graphics are older and the new ones wouldn’t match the bike. I base the 20 mm… Read more »
A couple of rough guides I’ve come across are: 1. You don’t want your arms locked out straight when on the hoods, rather you want to be able to comfortably have a slight flex at the elbow without being prostate on the Top Tube. It’s not easy to assess without having alternative Stems to hand but you can experiment a bit by seeing where your hands sit comfortably on the bars just short of the hoods. 2. The other is with your hands on the top of the hoods and a slight elbow flex, look down at the front hub.… Read more »
Thanks @Teocalli. If you are comfortable on a 90 with a Pina frame I would guess that a 100 is about right for me. The 120 is definitely too large for me.
Teocalli’s rough guides are just that and a good starting point. But this is really why a proper fitting can be so important. Everyone’s body dimensions and flexibility are different. I’m 5’8″ and my old school Hollands steel is real frame is 53cm with a 54.5cm top tube. I use a 120mm -17 degree stem with a 10mm spacer above the (threaded) head set. My more modern carbon Felt FC is 54cm but with slightly sloping stop tube that’s 54.5cm horizontal equivalent. With that, I use a 110mm -17 degree stem (slammed on top of semi-tall ~8mm head set top… Read more »
Rick, ask around at a local shop or other cyclists. Stems are one thing that they are likely to have a few used ones kicking around. Borrow a 100mm stem and give it a shot. If that works, buy one that fits aesthetically. I have multiple bikes and run 100, 120, 130mm stems depending upon frame geometry. These are all determined once I get my saddle in the same position on each bike (I use the same saddle on each bike too). The nice thing about modern (not quill) stems is that switching them out is a breeze and doesn’t… Read more »
My riding impressions blog post on Continental Grand Prix 5000 vs 4000 tires for Irwin Cycling.
Here’s a bit of recycling (pun not entirely intended). These Fixings and Fasteners come in a decent weight resealable bag that is just about the right size for a cycling pocket. Need to buy some longer screws but a packet of screws is still cheaper than a purpose made cycling pouch!
I had to re-read that – my first thought was why do you need to carry fixings and fasteners in your jersey pocket? For a long time I was using a zip lock bag, now I have a dedicated cycling pouch.
Thank goodness for UCI rules………….
Barf.
http://www.cyclingnews.com/news/mechanical-on-poggio-ruins-degenkolbs-chances-at-milan-san-remo/
At what point does a marketing gimmick become stupid? Didn’t work for Aqua Blue, doesn’t seem to be working for Trek. Did Degenkolb’s bike have a chain guide/catcher fitted? Crazy.
I saw him bouncing the bike with the chain off but didn’t spot he was on a 1x. Not sure how bouncing the bike would have got it back anyway. If he didn’t have a chain catcher I’d have thought he should have been able to get it back on as he did also reach down. So maybe it did have a chain catcher but still came off.
Mads Pedersen was using this on the cobbles with no apparent problems, and it works in cyclocross and mountain biking, so there should not be any reason for it not to work on the road. This season will be very instructive actually because the riders have a choice here (unlike at Aqua Blue since the 3T frame was 1x only). If we don’t see any Trek riders on 1x in long and flat-ish races later in the year (excluding time trials probably) then there are presumably some real problems with the 1x setup of the group.
I’d have thought that it was less likely to be used on long flat(wish) stages where having the right gear with closer ratios would be more important. Also potentially more likely to be used on TTs where typically a reduced set of gears would not be a problem. I’m also assuming that they would use splittable cassettes to set their own ratios – assuming the rules permit that vs standard shop bought ranges.
If I recall, the early noises last year from Aqua Blue riders were that this was fine on the flat-ish stuff (perhaps surprisingly) but the jury was out for climbing. This was after training camps with the new bikes but before any races. I have heard several others say that they got used to the bigger jumps easier than they expected (and in any case, that’s one thing an extra sprocket really does help with). Also 3T, among others I expect, have been making 1x specific cassettes to deal with range and closeness issues for specific terrain. We might see… Read more »
Squeaking jockey wheels – any advice beyond taking them out, cleaning and refitting?
Take out clean and refit or replace with ceramic bearing ones such as BBB who make some reasonably priced ones.
Pics of my Hollands with Irwin AON TLR 38 carbon wheels. What do y’all think?
Finally got them there! Nice and still with the down tube shifter for the front mech I see.
Though how do you find the different shape of the hoods when riding on the tops?
Yes. I love being able to manually trim the FD.
Modern hood shape along with the they blend with compact bend bars is more comfortable. Feels like you’re riding on top of them. The hoods on my Hollands (circa early 90s) are narrower and it feels like you’re reaching “down” into them. Especially with the shape of my ITM handlebars. But still comfortable enough.
Pictures seem to be fixed now. Let me know if you have any more issues!
Picture still not fixed! there’s no seat stays!
The BB and Chainstays are so stiff they are not needed. All built out of Graphene……………..
chuckp – seems to be a permissions thing – they screwed up a pile of permissions in an “update” last night as the files seem to load somewhere but are not visible in the Media Library. Grrr – will get my tech mate to investigate.
I’m not seeing anything. Maddening!
Yup – bear with me. Looking into it. Really pissed off with my Service Provider!
Ugh – just found something else that is not right behind the scenes. All is not well still with the fix for last night’s cockup of the site. Grrr…….
We’ll see what tomorrow brings!
OK so we seem to have found that my SP has set the Media Directory to Root access! I don’t have access to change that back. So have sent them (another) stroppy email. As you say, we’ll see what tomorrow brings. Hopefully they will not kill the site again overnight……..
Same as before.
Same as me … nothing … nada … zip … zero … the big bagel.
I suppose I could’ve put this in Photos, but decided Tech instead. My circa 1990 Hollands 653 Reynolds custom frameset that used to be my race bike way, way back in the day has gone Full Monty retro-mod. Put my Irwin AON TLR 38 carbon wheels on it when I found out you can use the spacer for a 10-speed cassette on an 11-speed freehub to run 8-speed. I also put on white Marque bar tape (BTW, I’ve decided of all the things bike maintenance related, I hate doing bar tape the most). Drivetrain is a bit of a mash-up:… Read more »
The photos didn’t post for some reason. Trying again.
@teocalli – I don’t know if it’s me or the site, but my photos aren’t posting.
I tried to post in photos and I got a message saying file exceeds maximum file size. Will try to make them smaller files and see if that works.
Let’s see if these pics post.
And they don’t. WTF???
Hmm – I’ll check. My SP had t rebuild the site this morning after they screwed it up last night and I did spot a few hangover issues…….
My latest for PEZ. Review of veloToze gloves and shoe covers. Perfect for the Classics and Belgian spring. Bring on Omloop!
https://www.pezcyclingnews.com/technspec/velotoze-not-popsicle-toes-or-fingers/
I love my Velotoze shoe covers, never tried the gloves though. Will have to check them out.
Not quite the finished product…going to lace up some Boyd Carbon 28mm deep tubulars for it to be on display with at NAHBS, but had to toss some wheels on her and take her for a spin!
Sweet!
Real men ride pink! Love it!
Virtually all of my fleet have some sort of pink involved!
Agreed, I must have 3 pink poloshirts, 1 pink rugbyshirt, pink dressshirts, pink tie, pink t-shirt (just got a pink karaoke shirt as well). No pink socks yet (old school rules, no worries ChuckP!). But 2 pink cycling jerseys. Bikes are pink-free however, mmmm.
Test riding Continental Grand Prix 5000 tires today. Irwin asked me to do a riding impressions write up for them.
Tacx to be acquired by Garmin. Some interesting thoughts here from DC Rainmaker.
The build begins…now I just have to wait for parts-
Wow, that’s nice! I have Bixxis on my short list for my next road bike, so I will be very interested in this build.
