Did you take any pictures of the frame after you cut it? Would love to see them.

Good morning guys. Just a quick question. I am thinking of getting a 256 from Peter and was wondering if there would be enough clearance at the chainstays to run a 34 tooth front single blade set up.

Yes, I'm riding with a NW 34T from AbsoluteBlack. Here are some pictures: http://chinertown.com/index.php/topic,184.msg7262.html#msg7262

What crank will you be using?

Thanks for the ideas JohnnyNT

I like to think of my bike as weight weenie on a budget.   

I really like the bike hub store hubs for the price to weight ratio. I am now using the 28 hole 27mm carbon hoops from Iplay with DT Swiss spokes. I really wish I had weighed them

All the bolts have been switched to aluminum or titanium.

My next part change will be the Extralite headset. Has anyone on this site tried the Extralite headset?? Would love to hear how it is working out.

Good to know you are alive and kicking after such crash. There are still some parts in the bike you could make lighter, but overally it's a very nice setup.

Thanks. I would love to hear what parts you recommend to get me in to the low 16 pound range or possibly high 15s. I kind of stopped adding to the spreadsheet so it's not very accurate list of the parts that are on it now.

I was thinking about the headset from Extralite would save some weight. I would love to get the new XTR brakes but would not be happy if they didn't stop as good as the XT brakes I have on now.

Strange, I didn't have any issues with my XTR M9000 with the KMC X11SL chain. I was also using the one up 45 t cog without issues.

I have been using this cassette for a fer months now and love it! It's so nice to have the top speed back! It shifts just as good as the XTR cassette it replaced. I use the 9 and 10 tooth for down hill and single track all the time. I am not standing up mashing on the crank when I am in the 9 and 10 tooth. It's really nice to keep my speed up so when I am approaching another hill I can ride up most of it before I need to shift. Single track sections that were once bumps are now jumps and I find myself using my brakes more. I finally have a 1x that is not a compromise!

I have been using the  IP-FK-052 from IPlay for about a 18 months and love it. I have not had any problems with it, works the same as the first day I started using it. I found a really light axle made for this fork. https://r2-bike.com/SHIFT-UP-Thru-Axle-QR15-for-Carbon-Rigid-Forks

I have been riding my 21" rigid IP 256 for about a year and a half. I am 6'2" 220 pounds, my bike is 16.6 pounds.  I thought I would give an update on how its been going.

I am always looking for lighter parts to try out on the bike.  I had  a response cassette along with the one up RADr derailleur cage mod. I was never really happy with how it was shifting. I finally went with an XTR 11 speed derailleur, shifter and 11-40 cassette. I could not believe how much better the shifting was. I added the one up 45 tooth cog to the mix and it still shifted great, I was using a 32t ring up front. I still was missing the top end speed. I ended up with the e13 9-44t cassette. The hub I was using from Bike Hub Store had interchangeable parts, so I could just get the XD driver which was required for the e13 cassette. I finally had a rage I could live with, and it still shifted as good as the XTR cassette.

I Had no idea how I would like riding a rigid mountain bike, with a carbon seat. I was surprised how much I liked it. Most of my rides are around an hour after work. On weekends I will do longer 2-3 hour rides, and have no issues with comfort. I ride all the same spots as when I had my hardtail. I never did crazy downhill or big jumps so the rigid was perfect for me. 

The axles were the last big weight savings. I am using a Extralite Black lock rear axle, and a Shift Up 15mm thru axle that is specifically designed for the rigid carbon fork. Both axles come to 69g. The front axle that came with the rigid fork is 82g. The rear that came with the bike was even more. I had purchased a lighter one on ebay that was 70g, but still double the weight of the Extralite rear axle.

As far as durability of the 256 I have only had one crash, and I was more damaged than the bike. In October I was on my usual after work ride going down a hill around 38mph and lost control. I don't remember the ride that day or anything for the next 5 days. I was in a medical induced coma for the first 3 days with a diagnosis of diffuse axonal brain injury. Lucky for me I have a heard head and was out of the ICU in 6 Days. The doctors thought I would be recovering for the next year learning  to walk and talk again. After a few weeks I was back to normal, with a few small breaks (face and ribs). The front rim was cracked, I am guessing from hitting one of the wood steps I was suppose to jump over. I called Jason and ordered a new rim. I had one other chip, on the frame but it was very small and just barely noticeable. The bike was ready and I was riding again in December.

I am not sure if I like this bike so much because it's a great bike or because it's a good bike that I built AND is functional. Purchasing a frame and building a bike really makes me appreciate so much more than just the ride. I have learned so much about bikes going through this build. I am a car mechanic, and have a great place to work on my bike. I have been purchasing bike tools as I need them. I enjoy helping my friends with their bikes, and showing them how to maintain them.

I love my rigid bike! I feel like It is complete, there is nothing I want to change. I am sure when I am older (I am 43) and start to feel the aches and pains from years of riding I will go back to suspension. For now I am just gong to enjoy the ride.

Has anyone tried the Extralite Shimano axle on their 256? I would love to see a picture of it on a 256.

Titanium will be real close to lighter than aluminum. And alot stronger.

Assuming comparable geometry of the nut, aluminum would be the lightest, with a density of 2.74 g/cm^3, titanium is 4.5 g/cm^3 - 66% heavier, and steel is 7.6 g/cm^3. Just make sure you don't get it made out of osmium, 22.57, or double that of lead!

Good to know! I found a steel nut at work and it was 10g more than the whole 15mm axle. I should have the titanium nut in a few days, I will weigh it and let you know. The aluminum nut that is on now is only 5 grams.

I found some titanium ones on ebay!! Not sure on the weight though. The aluminum nut on my ip265 is less than 8 grams. I am still happy to have something to try that is not steel (49grams).

I will still be looking for a aluminum nut but now I am not in such a rush.

Thanks for the idea Vipassana. My wife just quit as GM of a aerospace machine shop  . She has a lot of connections with shops that could do the work.  I just thought I would be able to find something easily, WRONG.

Nothing close on that site. The steel ones weigh more than the axle

I cant believe I cant find one

So I purchased a Fox Kabolt 15mm Axle for my rigid 29er fork on my IP-256.  I didn't think I would have such a problem finding an aluminum nut 14x1.5. The nut that came with my 15mm axle from www.xmiplay.com doesn't fit. Does anyone have an idea were I can get an aluminum nut that is 14x1.5?

Thanks!!

Has anyone replaced the bolts that hold the dropouts on the IP-256? I wanted to get some titanium bolts for them. The allen heads are a little bent out of shape on a few. If so where did you get them?

Anyone know the size of these bolts?
